Hello,
I'm searching for a Softwaretool for displaying the current available Network (such as HSDPA/EDGE/GPRS).
maybe someone knows such a tool!
You might shorten the standby time, since it'll have to check availability of the network quite often.
yes, but if some software uses a button for getting the current availability of Networks i would not have this Problem.
also the Field strength is an information i have to know!
download the HTC battery display plugin and when you go into the options of it you can view % of network signal as an additional option

what is the difference between these two settings on my N1? i get 3G/H with either setting, and they both switch to Edge around the same coverage areas too. PRL seems to have ever-so-slightly better dBm power readings, anyone else seen this? both seem to have similar network performance too (based on download speeds), should i stick with one or another? which gives better battery life?
TIA!
Hope this helps!!!
GSM Only - Only uses in G/E and never switches to 3G/H. Should have minimal battery usage.
GSM Auto (PRL) - Automatically switches between G/E/3G/H based on the PRL (Preferred Roaming List) for a provider on your phone. Not supported by all providers and may not be supported in certain regions. Should have moderate battery usage since it uses a predefined list to switch.
WCDMA Preferred - Automatically switches between G/E/3G/H based on the best/strongest signal available and is supported by all providers. Has high battery usage since it constantly scans the network for the strongest signal to switch.
WCDMA Only - Only uses HSDPA and will not switch to G/E/3G even if the HSPDA signal is too low. Use this only if you use your phone in a area with good coverage. Should have moderate battery usage.

thank you!! where'd you find this info?
There's a huge thread on this already. Gsm auto (PRL) gives me much better battery life over wcdma preferred but we really don't know exactly why. Both give you 3g and edge access.

i'm discovering the much better battery life as well, pleasantly surprised to be at 70% after coming off charger 11 hours ago!
do you have a link to that thread? i searched before I posted but couldn't find anything of value. xda is a great resource, but sometimes info is difficult to retrieve from old threads. thanks!

I believe the fact that GSM Auto (PRL) uses a predetermined PRL to switch between G/E/3G/H vs. the phone constantly scanning to find the best signal in the case of WCDMA Preferred is the reason for the better battery life.
many thanks for the responses guys, much appreciated!

Hi All,
I have a weird issue. My phone seems to be permantently stuck at "H" (HDSPA), it never switches back to 3G. Does anyone know what the problem could be?
It's sucking up my battery real fast.
I'm currently using a Generic Northamerican R3 rom. My phone is the X1a model.
Help would be much appreciated, thanks.
EDIT: I should also add that "Bands" option is set to Auto (both of them). If i play around i can get it to use Edge only, but thats not what i want. Id like it to work as it should, 3G when data is not being used, otherwise H.
download WMlonglife.cab n setting it..i forget the link..u can googling...
to the OP:
here's some info to let you figure out if you actually have a problem at all or not:
H(SDPA) is a data-extension of UMTS = 3G, E(DGE) is an extension of GSM/GPRS (always data, voice is either GSM or 3G). with band-setting, you just choose between gsm or 3g, if you get edge or hdspa for data depends on what your provider is delivering in that area.
standard behaviour with hdspa is to show the icon only if there's actually data transfered, if not it should show the 3g-icon. but some providers break that standard and will always let the phone show H.
so either you have one of those providers and are just complaining about the higher power-consumption of 3G compared to GSM. then normal power-saving measures come into play, search for them, there's a thread for it.
OR you don't have one of those providers, the symbol should fall back to 3G. this would mean you have constant data-transfer going on, causing higher power-consumption. if that's the case, remember what you installed and set to autostart (skype, irc-client, webradio... - web-stuff running in background)
I have performed many APN, ROM, and baseband experiments and have successfully routed out every variable contributing to signal loss on data, voice, drop call, and signal blackout. I can produce a full detailed on this if anyone wants. Will just take me some time to collect all my data.
To the limits of not be a Dev nor a coder I believe the issue is with how the phone handles frequency changes based on signal strength or data. There must be a code or script that tells the phone to switch to a lower band if the primary band is below a certain strength. If there is it can be changed to allow the band to be switched more effectively automatically if any of the Lowe bands exceed the primary bands signal strength beyond a certain tolerance. Thus insuring a constant signal strenght between all 3 bands that can be used automatically. The function is allready there and in use but it needs to be found and hacked.
This is where the Devs we rely on come in. The above is all theory and is the limit of my knowlage of how it works. Its the Devs that can take this idea and realise it. I am fairly sure this is the direct cause for the majority of our in call problems. I would be more than happy to vigorously test this and offer full reports if given the chance. If I'm wrong and I'm barking up the wrong tree here let me know please. I want to help but I really don't want to lead anyone the wrong way.
Thanks
[BUMP]
Developers (you know who you are) . Trying my best to help on this but it needs to be confirmed at minimum. Really need someone with more knowlage on this.
Thanks in advance oh wise and powerful developers. Consider your posteriors kissed. Lol
Thanks for taking the initiative on this. I have a couple questions:
How did you collect your data? (Not looking for a detailed answer, just a quick rundown)
Did you use a control?
So, im a little confused on what your looking for exactly. Are you asking if there is a way to hot switch the base bands on the fly automatically when signal strength is low?
I am interested to see what you have, but want to fully understand what your looking for.
Colbur
The majority of my data is notes. As a control I used the stock baseband, stock rom. Completely cleaned the phone of any app and used it solely for phone called during the day. I noted the signal strength changes when traveling in and out of various coverage zones. 2g 3g 4g . Made note of how long it took to change then moved again. Seemed very erratic in how the phone decides what signal to use. Couldn't seem to understand why in some cases it would stay on a 4g band when a 3g was twice as strong in the dame spot.
So after changing roms and apn's I cunducted the same experiment with the same average results. Used the same rout and time in stops.
Changed baseband same rom. Same experiment. Got the same average.
Changed baseband and rom again. Again same results.
I think the problem is how the phone decides what band is best at any given time. If its set to pic a band with a higher data rate then it would stick on 4g even though a 3g signal is much stronger. How often it changes is also an issue. Polling to often will drain the battery and depending on how the variables are set it will swing rapidly across bands while in use. It would be great to crack open the files that decides this so we can tweek it to fit our geographic location better.
An update
This specific behavior is in direct relation to the Baseband. While the APN is dealing with credentials the baseband in our case determines the hand shake and frequency from quadrant to quadrant when rolling past towers .
The other eminent and probably the most important is the refresh rate of the network. The more frequent its set to refresh the more it uses battery . If its set to low then you loose signal more often.

I'm assuming that this is going to be for a particular region as where I am, I never have experienced the issues with the phone as others have.
Detailing your region and the exact method you used to test this would be a good idea as well, that way others in different regions can test it out and see if they get the same results.
From what I notice on my phone (CM7.2+, v21E), when the signal strength goes below -110dB on 3G, it switches to 2G. My phone is the P920 so there's no 4G. I think using empirical data with hard numbers is better than using the number of bars as a gauge, since according to the P920 service manual:
In 3G
4 bars: over -88dBm +-2dBm
3-4 bars: -88dBm +-2dBm
2-3 bars: -96dBm +-2dBm
1-2 bars: -104dBm +-2dBm
0-1 bar: 110dBm +-2dBm (at this point it switches to 2G mode automatically)
In 2G
4 bars: over -91dBm +-2dBm
3-4 bars: -91dBm +-2dBm
2-3 bars: -99dBm +-2dBm
1-2 bars: -103dBm +-2dBm
0-1 bar: -105dBm +-2dBm
As seen from the above, there's a pretty large range between each bar of signal so numbers are better I think. Furthermore when you factor in the fact that dBm is calculated in logarithmic form, an increase of -10dBm (-80dBm --> -90dBm) would mean a 10000 fold decrease in performance.
This is fantastic data and a great post. What are you using to log your signal data?
Been using a few maps but I'm uncertain of there accuracy .
The LG stock rom only allows you to use the bars as a gauge of your signal strength. I'm using CM atm, it allows you to display your signal strength in dBm instead which is very helpful for things like this.
Cell tower information sometimes "Unknown" - Issues with Cell Near automation
Hi,
I have both tasker and automagic app profiles which are triggered based on cell tower informations. I discovered that altough my phone shows clear full reception signal and i can make calls, have data connection etc when i look via tasker or any other app that collects cell tower id's it gives a result of unknown. After a while this changes and the phone can again pick up actuall cell tower id's but it often switches back to unknown.
My issue with this is that this basically kills most of my location based automations on the phone and is driving me nuts.
Anyone else have similar issues with their HTC One and if yes know maybe a way to fix it?
Thanks
I may have found the problem (and the workaround). Since the HTC One is an LTE phone and my previous one (HTC One S where everything worked fine) wasen't i tried to change the Network mode from GSM / WCDMA / LTE auto to GSM / WCDMA auto only. Once i have done that the phone immediately was able to identify the cell tower network id. Of course this could be purely coincidental so only time will tell if this actually permanently fixes my issue but so far it seems to work.
I'm running xiaomi.eu 13.0.8.0 on my Note 10 Pro currently, though I'm not sure it matters for this.
When I have the Preferred network type set to "Prefer LTE" my phone locks onto LTE towers with a poor signal, typically around -117 to -123 dbm, ( > 2km away, 0-1 bars). Sometimes calls work, but often I get reports that people aren't able to call me, and if I make a call it may take several minutes of retrying before it finally switches to UMTS or GSM and the call goes through. There is a strong GSM signal close by, but it typically refuses to use it and prefers the unusable LTE signal instead.
Short of setting it to "2G only" is there any setting that would let the phone switch to a usable signal, when LTE is so bad?
VoWiFi might help in this case to get around the problem, but I haven't gotten that working, either.
reset phone settings. prefer it
redmi note 10 pro same device as yours and I know as I am facing another bug, same would U bcz firmware is latest I have debloated many apps from adb pm.... command.
A Bug I know exist most people wont know is about Cellular network Band. It adds jitter in connection.
And I have solution for that one but that require root. maybe not
But Trust me I know problem Thats it we can find solution
To know the problem, It is actual in band selection. If u check it and find a fix please share it here.
I am writing my fix here
---> Download app from Playstore called "Hidden Settings For Android" to see the problem.
---> now search "band"
U have to use little brain and see all three selections name.
---> FUN read this " Two system apps called System settings and Miui System settings have control over band selection. Right!
---> One open settings for band selection and other opens settings for band selection as same as we think but they are different apps and have different data storage settings they override each other if u select one band in one settings and two in another make both their selection buggy.
By default when i didnt found this I was experiencing bad network.
Then I selected same band on both settings and keep them open in background and by network run back to normal * more faster than other devices on same network provider
As soon as I remove both from background, later bug starts to happen again.
Interesting. I ended up getting vowifi working by contacting my service provider and asking them to enable it on my SIM. So I keep the phone in airplane mode with wifi enabled when I'm at home. That's working much better.
I did try "Reset Wi-Fi, mobile networks, and Bluetooth" before, several times, but it didn't seem to make a difference.
