This app will show quite a bit of info on both cell and wifi signals, and will also show you which cell tower you're connected to on a map. I'm in a building with a cell booster and the map is showing both the booster and the tower it's connecting to.
On the "RAW" tab it shows power in wattage. Mine currently shows the cell signal is at 630 fW (femto watts) which is crazy small, like 0.00000000000063 watts. Femto is 10^-15.
( #*2263# ) <-- on dialer. Switch to a different LTE band and see if you get better speeds also.. I use the app. https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&referrer=utm_source%3Dgoogle%26utm_medium%3Dorganic%26utm_term%3Dnetwork+cell+info+lite&pcampaignid=APPU_1_uo39XIOEF4KOsQXM5ZqYDA to check signal strength, and speedtest.net or fast.com for speeds.

Network Cell Info app let's you check what 2G/3G/4G/LTE band you're on, and more.
It's called Network Cell Info Lite. And yeah, perhaps you're right. Roaming registering as Freedom. If you look at the map, there are dots all over the east coast/Canada so you might be right..

That's a good shout if you're on the fringe of 5G I wonder if it's hopping between bands and losing connectivity.
You could actually get a technical view of what's happening with this App; https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
I used this at work for a cellular project recently.
edit: I don't notice any issues with reception but my country hasn't really rolled out 5G yet so I've not even been in an area that provides it.
You might want to install some cell-coverage apps, like Network Cell Info Lite or CellMapper, just to get some more concrete info...
100% true!
But the dialer code might not be present in all version - so people could also use a program like Network Cell Info Lite or some other similar.
And you can also see how in some cases by moving on a lower network type (down to 3G/2G) you might actually gain a lot in signal strength (which will lower battery drain).
Ok so what I did has fixed the issue. So if prior to the update your phone had WiFi calling it will still be on, however they have now hidden the options for "prefer WiFi over network" so by installing the app it opened the hidden options.
This is what I used https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
And this opens your options back up.
What you have said about *#800# no longer works for the option you need unfortunately (or at least the option I needed).
Try changing 'Network operators' from automatic to manual selection of a Nationwide roaming 'partner' - the list once it's generated won't display who's who, just the RAT (LTE and WCDMA) for each. You can confirm which provider with Network Cell Info once you're registered on a site.
Both Bell and Rogers serve the Blue Mountains area, Bell has more towers. You may have to experiment with each provider and RAT; WCDMA may give the most reliable inbound connection. Let us know how you make out.
Be sure to switch back to automatic selection when you head home.
RBT could make interop smoother and more reliable (eg. seamless handoffs), but... RBT. They won't do anymore than the minimum required where Freedom's concerned.
Download this and see how close in signal strength your wi fi is to your cell. https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_US
Download this app and check which network band your global phone is using.
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Also check your phones model number and then compare the band info on a site like gsmarena.com
I use this app. Network Cell Info Lite ....It will show you what band, and will map the tower you connect to along with singnal strength. It has helped me solve connection issues and give me some ammo when I talk to my carrier.
>is a cell network monitor and measurements log tool (4G+, LTE, CDMA, WCDMA, GSM). It provides also WiFi info (beta).
I use it to diagnose what's going on with my phone when it can't get a signal and view the handshake process. I paid for the pro version and I love it.
Also, I love Substratum (app themeing) and can't live without it. I'm refusing to upgrade my Pixel to Pie because I don't want to lose Substratum.
​
Grab Network Cell Info Lite and it will give you the carrier info on the Raw tab. For example, if it says the operator is 720 then you are on Rogers. If it says 220 then you are on Telus. These aren't the only operator numbers for these carriers. For a more complete list checkout Wikipedia.
sprint has always been a pretty useless network. if you have an android phone, download the app named Network Cell Info to see what tower you're on & a lot of useful stats.
if the problem only exists in a given area (one or more towers) then you can report that to the service provider - more detailed information means a faster resolution.
What's LTR? Where are you located?
Use an app like Network Cell Info Lite to see if the device is indeed connecting to the closest tower properly.
Were you in an airplane vs a jet airliner? I've tried many times in an airliner, and never had success. Could never get a signal. I talked to an ATT engineer once and he said tower antenna are pointed in a N,S,E,W direction, not vertically, although there's leakage. He also said algorithms handing off from tower to tower are not programed to work at 450mph. I've been on flights before where I could receive and send email, but thats all done through a local network on the aircraft and routed through satellite comms.
Using this app, I've checked it taking off from Detroit and Chicago. Always seemed to lose the signals completely around 10,000 ft.
There's an app I forgot to mention yesterday that I used to find out where the nearest tower to me was (when I had awful Rogers reception). It let me know the closest tower to me was all the way at the Woodroffe Farmboy, when I'm in RSS. Now the Virgin tower is within spitting distance.
The tab you'd be interested in switching to if you get that app will be the map tab all the way to the right of the screen. You can also stand a little bit in each part of your house and it will give you numerical and colour coded readings as to the signal strength. Really useful even for a free app.
There are several. I've used this one in the past... https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Opensignal is another..
https://play.google.com/store/apps/details?id=com.staircase3.opensignal
Search cell tower mapper on playstore.
Find one that works for you.
No problem at all.
If you're on iOS you can check which band you're currently connected to under the field test mode you access through your phone's dialer, see instructions a little down this page.
If you're on Android, you can get similar info with dialer code "*#*#4636#*#*", going to phone info. It's hard to sort out on this screen so I usually recommend grabbing an app instead, this one tends to be my go to.
I have an android phone and used this app:
Network Cell Info Lite & Wifi - Apps on Google Play
It showed me the cell towers and where the signal was best. A parabolic reflector should help you focus on the tower you want (and block the other). Of course, your mileage may vary.
Are you using an Android or iPhone?
If you're using Android, download Network Cell Info Lite (https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_CA&gl=US)
See what band you're connecting to
If you're connecting to 2, 4, 7, 66, 71, these are high bands with very small footprint.
Ideally you want to be connecting to 5, 12, 13, 17, 29, 31 (high band, wide range).
Network cell into https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite here is an app that Nic Hawks (Grisle King) mentioned to analyze existing 5G coverage to assist in 5G hotspot placement. This doesn't answer your question but it's a related tool.
I get absolutely terrible coverage on my Pixel 6 Pro as well. However I blame Google and Mint.
The fist thing to do is to check your signal strength:
- Network Cell Signal Lite
- or Settings -> About Phone -> Sim Status (Choose your Mint SIM) -> Review Signal Strength - Chart
I live in a pretty bad spot for most providers but even when I get into places with better signal, my phone will sometimes run like crap - Exclamation mark by the signal bar, super slow data load times...
At my desk, in the office at my house I am getting -115 dBm which really really sucks.
Ubiquity нямат lte router + antenna в едно. Можеш отедлно да ги вземеш ама там по-добре да отидеш към рутери които по лесно се сетъпват. Mikrotik имат и друга антена която бууства до -21db. Но като цяло не ако не си tech savvy, забрави за Mikrotik.
Директна видимост не е задължелна. Повече те интересува стабилността на сигнала което може да се види с app-ове като този
Are you able to get on your roof and see if you get some signal up there? If you could install Network Cell Info so I can get an idea of how strong the signal is and what band you're connected to that would be even better. If there's at least one bar you could get a cell booster instead of the network extender, as it's a glorified signal repeater instead of a micro cell tower. I would need to know how strong of signal you get and how large your house is before I could recommend a specific model. They're not cheap, but it's your only option if you're not a direct Verizon customer.

Mungkin bisa dicek dulu status tangkapan sinyalnya menggunakan aplikasi Network Cell Info Lite & Wifi atau Opensignal - 5G, 4G, 3G Internet & WiFi Speed Test di Android?
I like your positive energy.
Ada kenalan yg bekerja d perusahaan mitra Telkomsel/Indosat sebagai perawat tower the real BTS, dia bilang, jika ada gangguan, laporan dr Telkomsel/Operator lah sebagai acuan utk melakukan aksi, misal recalibrate antenna, memastikan aliran listrik normal dst., kalau mau langsung ke team dia, bisa, tp harus nungguin dia datang ke site, atau tanya orang disekitar site, dan bagaimana kamu tahu tower terdekat yg terkoneksi dg HP mu?
Download Network Cell Info Lite di PS
Oia, 1 trik dr dia, jaringan 3G atau UMTS /HSPA/HSDPA etc, coba d pakai, krn 4G sudah over crowded, biasanya sih kamu sendirian d jaringan itu.
Passing around the good little trick, semoga ~~menantu~~ membantu
I totally missed the part of this post where you're a technician - nice! Are you on Android or iPhone? I have a great Android app i use to give me details on my LTE connection, we could compare numbers, see if we can figure out whats going on. The app on Android is called Network Cell Info - https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_US&gl=US
I don't know if its on iPhone or not.

Here's the app I've been using to determine which band the handset is connecting to:
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Does this occur with wired AA at the same spot? I asked because about 3 yrs ago, some users in official AA community forum reported AA always disconnected at the same spots along their daily route where he knew cell signals changed from 4G/3G to any 2G variants. I've not been following the case or actively looking out if this is still a current bug. Sadly AA network status icon is not accurate else you could simply monitor it. I suggest one of you as pax use an app like Network Cell Info Lite to actively monitor as you pass by these areas to see if it's related to cell tower/station switching, not necessary just switching to 2G or blind spots where there's no coverage.
If it's not related to the above, what about Wi-Fi connection itself? Automatically connect to open network and automatically switching network settings are 2 settings off the top of my head that may cause WiFi switching.
If it's also not due to this, perhaps you've passed by an area with strong signal interference?
Have a look at this thread also related to wireless AA disconnection though yours is limited to known location.
Northwestern Ontario, basically as soon as I get a few KM out of a city centre, I'm on one of the mentioned 700MHz LTE bands. Band 4 is AWS 2100/1700 MHz. Towers typically have a few frequencies on them since the higher the frequency the more bandwidth available but the lower frequency bands go much much farther and penetrate buildings/trees better.
You can use the tower map to determine if the towers in your vicinity have 700MHz antennas on them and that will rule out if you're missing out on connectivity or not. Make sure to check Bell towers in the east as that's what we connect to with Public. Which bands in particular is a bit harder to determine. You can ask a friend with an Android phone on either Bell, Telus, or any of their subsidiaries to run an app like Network Cell Info in various locations around you and it will display which band(s) the device is connected to at the given time.
Tower Map: https://www.ertyu.org/steven_nikkel/cancellsites.html Network Cell Info: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Try to go to SIM card manager and set your SIM(s) to 3G/2G and see if that makes a difference. Maybe use https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite to check levels easier. There is also a separate big difference if you have 2 SIMs (but in my tests Samsung had by far the best handling of that).
Use an app like this to locate the tower you're connecting to within and outside base.
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
In my case, slow throughput wasn't due to congestion but a combination of distance, phone defaulting to high frequency band 66 which is suboptimal for propagation and tower surrounded by trees. After locating the tower and standing next to it the throughput was significantly better.
On the back glass, i had "DUOS".
In my settings the model number was "SM-N960F"
BUT, on the back glass: "SM-N960F/DS SAMSUNG"
Other things i can see, in "Network Cell Info Lite" app
Device + Sim tab : and i see SIM1 Info and SIM2 Info
I've been to that page, but those codes don't have the info.
I found this app which seems a little more in line with the feature I'm trying to get, but it also may be that LG doesn't show that info like Samsung did and the best I'm going get is one band being shown
https://www.cellmapper.net/map and network cell info lite helps me get the goods on my service.
Turns out I'm not using the nearest tower that I could be, due to terrain.
I got an amplifier that has a roof antenna and a little guy inside, and pointed the directional roof antenna towards my good tower. Get -85 dB now and great voice quality. Going to drop my landline once this covid thing ends (I might need to fax stuff between my doctor and work)
Yup on Android there are quite a few, I use Network Cell Info https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite and Cellmapper https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper
Maybe you could try this. Put the sim in your working phone and run this app - https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
See what band it's using for 2g/3g. Then look up your Oneplus phone band list and see if it's supposed to support it. Maybe it just doesn't support those bands.
I see. If you're using cellular data, then you can still do something about it. For example, moving out of the way of concrete buildings blocking the signal. See also apps like this one that allow you to debug how stromg your signal is.

Also this app shows current uses band
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
If you have any model other than G960U, then you’re missing the new frequency for Band 71 (600 MHz). If it’s T-Mobile branded or unlocked from Samsung, then you should be good.
Check here https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_US and you’ll see what band you’re connected to.
I’m not familiar with Samsung but you can search and see if there is a way to force the use of Band 71. (Someone may see this and help?).
I was having issues like this years ago, and it turns out I was connecting to someone’s home cell spot and they had horrible internet. Does this happen everywhere?
PS: Former Navy CTM2 here. Thank you for your service!
Sorry but even if the phone doesn't support the band 20, you can use 4g. Band 20 is mostly used in rural places. With this app, you can see which band your phone is using that moment.
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
> Sprint phones will never display they are roaming, or an R, while on T-Mobile
If you say so. Our carrier unlocked Pixel 2 and carrier unlocked Moto G6 devices beg to differ.
I have an app that shows me the bands, and our Pixel/Moto devices clearly shows an 'r' next to the LTE upper right corner when on TMobile.
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
You can check current band using a tool like Network Cell Info. I'd be curious if you could confirm whether my theory is correct, everything I have read and understand it seems to be the case but no official word yet, also no contradictory information as of yet either.
In EU, B20 is only used outside the city center in small villages.
If you live in a big city you should have no problems. ;)
But if still in doubt there is an app called Network Cell info lite.
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
The app connects to towers and tells you what band of LTE it’s using.

OP, download Network Cell Info Lite and share a screenshot of the gauge. I'm skeptical that this is AT&T actually throttling because your upload and download are so close. On Verizon, my upload was 7x better then my download.

I just got the Pixel 3a xl a couple of weeks of a go. I came from a 5-year-old Motorola Droid. Incidentally, I heard some time ago that Motorola had the best Radio/Cell signals.
I have a weak cell signal in my place -110 -120 DB. However, I have never had any complaints from anyone about my cell going "in and out".
I now have had 3 people tell me that "I lost you". So this Pixel 3a doesn't have the cell strength of the Motorola, but then, I doubt if any phone does.
I have since enabled wi fi calling which is better but a friend told me that she thought my voice didn't sound as clear or crisp as with the old phone.
Pisser for home use.
However, my work signal is -70 DB or so, and no complaints there as of yet.
​
Here is the tool I used to measure cell strength. https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_US . See if you are in a weak cell area. If not and still problems then that is a different story.
>I've never used preferred network type in the history of smartphones.
Well my S5 G900M klte LineageOS 15.1 is Lte capable but where I live when @ home the LTE signal strength fluctuates all the time between -95 & -65 dBm as seen in > About phone > SIM status which consumes battery while in Preferred network type GSM/WCDMA it's an excellent solid -50 dBm. (The lower the number the better)
You can also use an app like Network Cell Info Lite for example to check the signal quality besides the signal bars on the status bar.
I included some screenshots of it in this XDA official LineageOS 15.1 S5 kltexxx thread S5 SM-G900P LTE Problem.
So when connected to Wifi especially @ home GSM/WCDMA or just GSM (2g) is better to extend battery life while out & about GSM/WCDMA/LTE is better for internet speed and Wifi is one of the current triggers available in LineageOS 15.1 > System profiles.
AWS-1 (Band 4) is part of AWS-3 (Band 66), being blocks ABCDEF of the ABCDEFGHIJ.
Freedom Mobile has began to use MFBI (Multi Frequency Band Indicator) in parts of its network, so it is possible you are seeing the signal bars on these devices being similar due to this change.
^(As there are no standards for signal bar visualization, each company will differ how field strength is displayed. dBm/dBµ is the actual measure of this property, which is displayed by the options below.)
You have an Android device, so install an application like Network Cell Info Lite or LTE Discovery to see what Band you are actually connected to, at those instances you are doing comparisons.
The Apple device will need to access the Service Menu to view these details by typing *3001#12345#* into the Phone/Dialer app. Serving Cell Info under Field Test will show Band Info and Signal Strength.
If you're not rooted, this app helps (which is what I use): https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
If you're rooted, the best app for you is: https://play.google.com/store/apps/details?id=com.qtrun.QuickTest
Turns out O2 has started to roll-out Band 3 towers in some urban areas, I would assume Stanstead is among those. Your device supports band 3, it doesn't support band 20 which is used by O2 for UK wide coverage (and urban indoor coverage).
You can install cell info and confirm that you are on one of London's band 3 towers: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
If you are actually able to use any of O2's band 20 (800Mhz) LTE network with your Mi6, please, by all means tell me where you bought it. According to all accounts, no such Mi6 exists (yet) but if it does - I'll buy one in a heartbeat.
the one I'm using now is https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite I'm sure there are better ones but this was the first I stumbled across that didn't seem like ad-infested spyware at first glance.
There are a lot of apps (for android at least) that will show you what band your phone is on - some of them are kind of ad-ridden but i've been using this one: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite I don't know if it's possible to get the info on an iphone, but maybe.
Interesting. Thanks for the followup. I've driven around the American West a lot and I use Network Cell Info Lite to see towers around me and find a suitable camping spot for the night when there's limited cell reception.
Just installed the 4G LTE Cellspot, and downloaded this, which I should have done a long time ago.
I'm not sure what android and iPhone use to calculate their network bars, but, I think it involves rolling dice.
Our old signal strength was abysmal, around -115 to -130 dBm. Now the worst I can find is around -90 in the basement.
Since my wife isn't home yet, I'm not 100% sure that it's fixed, but, I am solidly 99% sure ;-)
Thank you again for your help!
I would suggest installing this app on your V20 and the Pixel if you still have access to it. https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en
See if you are connecting to the same tower & band on both phones and compare the signal strength. The "bars" as reported by the phone are not a very accurate indicator of signal quality.

Very weak signal but enough to mess with connecting to the actual 'tower'.

https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en I'll just leave this right here...
I can't talk to options 1 or 3 but if you are looking into the viability of a cell booster then your first step should be looking at some signal testing. With Android its relatively easy to do. I would recommend this app for testing:
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_US
Here are more detailed steps and explanations on testing as well: https://www.waveform.com/pages/field-test-mode
If your RSSNR is below 0 dB and your RSRP is less than -120 dBm then a booster likely wont work well and 1 and 3 will be the next best bet.
The booster doesn't necessarily have a hard limit on the amount of phones/devices it can support but from typical experience 10+ wont be an issue.
Also if you like come check out r/CellBoosters I am mod there :)
Thanks a lot for the response! I've read some stuff and made some tests:
Short conclusion: yes, the chip you posted is supported in my town (Santo André, state of São Paulo) by Claro carrier.
Long conclusion:
Accordingly https://www.frequencycheck.com/carriers/claro-brazil and some other sites I've read Brazil use the LTE bands:
B1 (also known as "IMT" 2100 MHz, UMTS protocol)
B3 ("DCS", 1800, GSM protocol)
B5 ("Cellular", 850, UMTS)
B8 ("eGSM", 900, GSM)
B7 ("IMTe", 2600, LTE)
B28 ("APT", 700, I dont known which protocol it uses)
​
I used this table to "translate" the frequencies: https://en.wikipedia.org/wiki/LTE_frequency_bands#Frequency_bands_and_channel_bandwidths
​
The last one (B28) is not on the frequencycheck: its the same frequency used by analog TV (finally deactivated here by 2016, I think). Source (portuguese): https://www.teleco.com.br/areasc.asp
I still couldn't find the official information on carrier site, may be the carrier uses other frequencies not listed on frequencycheck.
​
Accordingly this app:
https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
My current phone (a Redmi 4X, connect throught a Claro simcard) uses Bands 1 and 5, depending the configuration. I couldnt connect to 2G here, Im not sure if its available nor my phone supports this (and I dont care about this right now).
At the risk of being abusive: Claro is starting to implement 5G (DSS) in São Paulo. Does this chip supports this tecnology? How can I find if it does?
I still reading about this, I dont understood which LTE bands 5G uses, or if its even related to LTE.

>Mine is 45,9 (on a lab scale) and I get about 1d of standby and about 2h SOT (not using my phone to much). What do you think?
Everything is relative.
The biggest challenge with scientific experiments is to control all the variables.
Your standby time depends on which S5 model exactly, if using 2g, 3g or 4g, quality & constance of signal received by cell towers & what your phone is doing during it's maintenance windows between 2 doze sessions like if Sync is enabled, Wifi enabled for data, the number of accounts you have setup, pinging to fetch push email, WhatsApp, etc, etc.
See Doze explanations & illustration in Android Developers' Optimize for Doze and App Standby
For example where I live when @ home the LTE signal strength fluctuates all the time between -95 & -65 dBm as seen in > About phone > SIM status which consumes battery while in Mobile network > Advanced > Preferred network type > GSM/WCDMA selected it's an excellent solid -50 dBm. (The lower the number the better)
You can also use an app like Network Cell Info Lite for example to check the signal quality besides the signal bars on the status bar & it includes some logs of the cell signal fluctuation via a graph.
The SOT time depends on the screen brightness & what you are doing while the screen is on. With the Super AMOLED screen of the S5 if there is a lot of black on the screen it will use less power compared to if with a lot of white.
That's why I chose in S5 klte LOS 15.1 > Settings > Display > expand Advanced > Style (Chose system colors) > Dark mode > Black.
And in in Style > Style > Dark & in Accent color Default (the LineageOS Teal) .
In LineageOS 15.1 > Settings > Display > Brightness it shows a percentage & if Adaptive brightness is off then you can compare two identical phones or 2 different batteries in the same phone.
Keeping the screen brightness to the lowest while still comfortable is one of the settins that has the most impact on battery life unless you don't use the phone at all for very long periods.
There is no app or easy method to measure the real battery capacity: how to measure the real capacity of a battery
To extend battery life I use BBS linked in this post in this thread and the buried in LineageOS 15.1 > Settings > Security & privacy > Trust > Privacy Guard > 3-dots > Advanced & swap between the between Location, Personal, Messaging, Media, Device, Run in Background (my favorite), Bootup (love that one too), Root access & Other panels > long-press a given app & grant or refuse some permissions according to your need.
Desktop > Widget > Settings > Privacy Guard and it will create a direct shortcut to Privacy Guard Advanced.
I use it often to check what's loading on reboot as many apps want to start at boot when it's really not necessary when using them only occasionally.

I can't explain why your battery is heavier than Samsung's current 45.2g specs.
Maybe their first gen batteries for that model was heavier? While the S5 was launched in 2014 my SM-G900M was built in August 2015 as shown in DevCheck > System > Manufacturing date.
I like this app if your on Android https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Nice. For comparison, here's another similar app: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Just some words in the beginning. Basically, when you are done with that project you can apply to a job and you will be accepted as well. Your project is on the Bachelor thesis project level if not on a Master thesis project level (that if you also learn the theoretical part of what I'm going to mention). That project will take at least 4 months if not more.
As I have worked with something similar during one of my university courses then I will tell some stuff:
First the part of finding a route between your origin and a destination. If you are going to make it by yourself then you have to read about Traveling Salesman' problem. Basically you need to study graph theory. How to decide the shortest path between point A and point B, what kind of path finding algorithm to use, etc.
But if I'm correct, there is an API for that from Google Maps. So you might not have to invent it from zero and can get the path from the API. But it will help a lot to learn what I mentioned in the previous paragraph.
Then cellular coverage. Get yourself "Network Cell Info Lite & Wifi" app. https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite At first you can just play around with it and look what you can see from different views. Learn to use it and learn to understand what each thing means in the app. There will be A LOT googling. Basically you'll be taking part of a university course while learning cellular networks and that app. To make thing a bit less scary it has a map that shows cell towers on it while you walk around. It shows you the cell towers it can get signal from. So play around with that a bit.
Learn the connection between signal strength and also between the distance from a cell tower. Also I suggest to google+learn how the phone is deciding which cell tower it will connect to. Sometimes when walking around you can see how your phone is changing cell towers. Try to understand based on what it does it.
Now, to cell towers themselves. There are two options:
- You'll be making an app that is discovering cell towers and broadcasting the location of said cell tower to some web service where you'll be saving that data to a database. So at first it can't find any cell towers on a route and is relying on you and other people discovering said cell towers and gathering the information for future use.
- Try to find some sort of data set where is listed the location of different cell towers. Perhaps M2Catalyst (the producer of cell info app) has a data set already. I won't be surprised if their app is already collecting the data and sending to their server. But if M2Catalys has no such data set then try to find the location of cell towers from somewhere else.
Then finding suitable cell towers related to your route from point A to point B. When you were playing around with the app that I suggested you probably learnt (that talk goes for "future you") the connection between signal strength, when and why the phone is changing cell towers and also between the distance of cell tower from you. Also you have to consider obstacles that are blocking cell tower signal. Look into that as well to include it in your calculations. For example in the forest the signal is bad, on the field it is good, inside a building it is weaker. Etc. Look into that.
Getting back to cell towers and your route from point A to point B. You have to learn how to find the shortest distance between a point (cell tower) and a line (your path). That concept falls to mathematics and data mining field. You will need it to tell which cell towers are close enough from your route and which ones are out of your path and you won't be able to connect to them. Imagine a line and then a point outside that line. Keep drawing lines between the point and your route. From certain moment the distance grows too big and the signal breaks between your phone and a cell tower. And you have to do similar calculations for all cell towers and all points in your route. Sure, you can set some maximum length for the drawable line to not go over. For example the length when the signal will break. So it will calculate faster.
So you have to calculate it for all cell towers close to your path (also you have to find out what means "close", how will you define that? Again distance calculation). If all of them are covering your path either with weaker signal or with stronger signal then your path is covered with cellular coverage.
All of that was right now technologies, topics and theory. Now I get to a practical part:
Decide if you are going to use a web application, desktop application or a phone app. If you don't find a data set of cell towers then you HAVE TO make a phone app. If you can access a data set then anything is fine.
For a web application you will need a back end language, its framework, perhaps a database, also some server where you are running your web application (it will not be a static web page) but it can be also your own laptop that is running a web server in it, and from the front end side you will need HTML, CSS and some Javascript library.
For a desktop application you will need either C++, C# or Java. Sure, you can also consider Python for desktop applications but I would pick something from the first three. You won't need a server as the application will be running from your desktop. Perhaps you need a database but perhaps not. Better is to learn database as well.
And for an android app you need either Java, Kotlin, Swift (for iOS), React Native or Flutter. Probably there are more options as well that I don't remember right now. All of these are alternative. If I would be you I would pick either Java or Kotlin, and for iOS I would pick Swift.
Here's the app that he mentions I'm using it to visualize coverage of perspective areas of my customer locations. https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
For an idea of where nearby Rogers cellular towers are located you can check the Canadian Cellular Towers map, link below should be centred on Kentville, but with only Rogers towers active in the map.
You might check the cellular signal strength with an app like Network Cell Info Lite (Android link) or similar to see the raw signal strength.

You need the physical SIM and NO eSIM.
I just went through this myself. My physical SIM got corrupted, so they had me download an eSIM. But that means the DSDS auto-switch functionality is broken.
If you have a physical SIM and no eSIM, Google will silently download an eSIM to your phone that doesn't actually show up in your SIM list. It gets used whenever Google decides a network switch is in order.
See here: https://support.google.com/fi/answer/7540641?hl=en
Specifically, the instructions are:If you add a SIM card after you activate FI with your eSIM and see 2 mobile data indicators, follow the steps below.
- Remove your SIM card.
- Open your phone's Settings app.
- Tap Network & internet and then Mobile networks and then Google Fi and then Erase SIM.
- Reinsert the SIM card.
- Open the Google Fi app.
- Follow the on-screen instructions.
Then you can have a look in: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
If you see two signals, you've got 2 SIMs, even though you didn't manually download a different one.
This is so you still have the ability to download an eSIM from a different provider, or to have a physical SIM from, say, T-Mobile with 1 phone number and an eSIM from Fi. Or, perhaps you're going on vacation and want a local SIM for cheap data, but still want to be able to get a phone call.
The DSDS means "dual sim, dual standby" so it requires the second SIM, but Google doesn't show you the second Fi one. Instead, they're probably downloading secondary eSIMs and erasing them based on the providers in your area. They still need it though, because it maintains a low-bandwidth data connection to the second provider's tower. That existing connection is how they seamlessly switch between the two.
If u/intodarkes is seeing a second signal bar, they need to hit up the link above and follow the instructions.
Edit: If you don't get the second SIM silently provisioned, there's a dialer code to "fix" things: *#*#fixme#*#*
Honestly, no. All the information that NSG(network signal guru) is able to get it can get because of root access. There's a few other CellMapper-like apps on the playstore however they all use the same information that is provided by the Cell ID Api on Android, thus if the API doesn't have information about NR bandwidth (which it's not gonna have without SA 5G), neither will the non-root apps.
Here's a few of my recommendations that are similar but again you won't get anywhere near as much information as you would with NSG.
Northwestern Ontario, basically as soon as I get a few KM out of a city centre, I'm on one of the mentioned 700MHz LTE bands. Band 4 is AWS 2100/1700 MHz. Towers typically have a few frequencies on them since the higher the frequency the more bandwidth available but the lower frequency bands go much much farther and penetrate buildings/trees better.
You can use the tower map to determine if the towers in your vicinity have 700MHz antennas on them and that will rule out if you're missing out on connectivity or not. Make sure to check Bell towers in the east as that's what we connect to with Public. Which bands in particular is a bit harder to determine. You can ask a friend with an Android phone on either Bell, Telus, or any of their subsidiaries to run an app like Network Cell Info in various locations around you and it will display which band(s) the device is connected to at the given time.

This is what I use when I'm looking around the Rogue Siskiyou, Six Rivers and Klamath areas for legal places I can stay. If you find an area you want to explore, look at the laws regarding dispersed camping in that area. Dispersed camping is allowed on public land for a period not to exceed 14 days within a 28 consecutive day period and after 14 days you have to move at least 25 miles to a new spot. But your in luck! There is an endless supply of great free places to stay in Northern California and Oregon. I use Google maps and cell tower maps to find places I can stay and get service to work remotely. There are tons of roads that snake all over the back country here and you can go the whole time without seeing anyone. Be careful and prepared, some of the roads are old unmaintained logging roads that you will get stuck in if it rains and gets muddy! If you need help looking for safe spots in an area, let me know and I can show you what I look for.

According to this site as of June 30, looks like low-band 5G is in some parts of Eugene/Springfield.

This says it was available as of June 29. What I can't find is a list or map showing which towers have 5G in the area. The ones I know of are crowd-sourced and haven't been updated yet.
If anyone is feeling up to it and has an Android 5G enabled phone, download this app and if you notice 5G then open it and see where the tower is. Across the top are menu items like Gauge, Speed, Raw, and so on. Slide it over and click map to see where the tower is then share it here.

Hey OP, I'm back. With data, there are two main standards: CDMA and GSM. This doesn't affect you now because AT&T is CDMA, but CDMA will not allow you to use just any phone so be careful of this in the future if you decide to switch carriers.
Next up is data bands. [Here](https://www.gsmarena.com/xiaomi_mi_9t-9738.php) you can see the bands that the Mi9T is able to use (if you click the network tab drop-down). You of course mainly want to pay attention to the 4G bands.
AT&T uses the following bands:
2, 4, 5, 12*, 14, 17*, 29, 30, 66
12 and 17 are AT&T's main bands. Now as you can see, the Mi9T is not capable of utilizing the main bands. You can also use [this](https://www.frequencycheck.com/carrier-compatibility/9oGQcZ/xiaomi-mi-9t-standard-edition-global-dual-sim-td-lte-128gb-m1903f10g-xiaomi-davinci/at-t-united-states) compatibility check tool, though I find it's usually better to look manually. So the Mi9T will likely work in your area, just not with the best connection. You may also want to look into bands which are most used in your local area, because it varies across the U.S..
To check further, you could download tools such as:
Network Cell Info Lite: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en_US
LTE Discovery: https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery&hl=en_US
I believe these are both available in the Apple app store, but I don't have an iPhone to check/link them. With these you can see which bands you currently use most the time, which may also influence your decision.
Hopefully this all helps! I'm no expert, but my first xiaomi phone was the Pocophone which was basically unusable in the U.S. so I ended up doing a lot of research on the topic. Hopefully this helps you from making the same mistake I did!

Strange, Tele2 only has 4G bands 7,20 which are the exact ones missing on the Chinese version. Check that its the Chinese version before returning.

Many cell network monitoring apps can tell you what network band you are connected to, like network cell info. Network signal guru can tell which bands are supported on the phone but it might need root permissions, so you might want to uninstall the app when you are done.

The bottom antenna might not have been re-seated sufficiently causing signal loss or dropouts.
Review the photos below:

Did you replace the antenna by using all four mounting screws and are they sufficiently tightened?
You might also want to confirm that the dropped signals are actually due to your device and not just the environment you're in. A handy app I personally use to determine radio signal strength is "Network Cell Info" of which has a free "lite" version available for testing.

Folks experiencing slow LTE speeds are welcome to private message me with your situation and I'll try to help you diagnose what could be the root cause. I've learned a lot from optimizing my own LTE signal / speed that can hopefully help you. Please include the following:
1) Your RSRP signal reading when connected via LTE (more info at http://www.ubersignal.com/field-test-mode).
On iPhone, Dial 3001#12345# and press the Call button. It's the negative number in the top left status bar (make sure you're connected to LTE).
On Android, download Network Cell Info Lite (https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite&hl=en). You might find their Maps tab handy as well to find out where the tower to which you're connected is located.
To find it on a JetPack, follow the instructions here for most devices: https://www.verizonwireless.com/support/knowledge-base-209160/. It's under "4G LTE Network" after you scroll down on the Diagnostics page.
2) Your SINR
Not sure if it's possible for iPhone; use links above for other devices.
3) Your City & State and a description of the immediate area (i.e., rural vs urban, indoors vs outdoors, flat vs hilly, etc).
4) The device the SIM Card is inside and whether any antenna or booster is being used (if the SIM is not inside a phone, include how you're connecting to it - i.e., "connecting to my 7730L JetPack from my iPhone 7 via 5GHz Wi-Fi").
5) Your current upload and download speeds, as well as what it has been historically and whether any other variables have changed recently.
