Hi, I'm developing an application for Windows Mobile. I got stuck in the problem that I tried to get all the CellIds and Signal Strength of all the nearby Base Stations of my PPC. I tried the RIL but just could get strongest signal strength of 1 base station (I believe). So my question is that : is there a way or method so that enables me to scan all the nearby base stations with their signal strength? I would appreciate much if someone can help.
Thank you.
Hello Seniors,
Wanted to know that is there any application which will show the signal strength (in some number) of all the network provider in my area.
Say, I have a Vodafone sim and in my area there are 5-6 different operators. So is there any way where I can check that in my house, out of all the mobile providers whose signal is the strongest?
So I am looking for a tool which will check the strength of all and then I can come to some conclusion.
Again, there is no network signal map which is available in my area, so need to depend on some app or some software etc.
Looking forward for your guidance.
Regards,
Anoop.
There is an app called as Network Info II on the playstore. It gives you the strength of the signal for the sim that is currently registered thru the phone on the network.
It wont give for other available networks..
May be somebody else can suggest some other app..

hi all i am losing signal all the time from my network is there any commands or secret menus to look at the signal or change the frequencies in order to get my phone working as it should ?
Is there a way to switch the display signal strength meter from showing 4G LTE to regular voice signal?

This is the link on how to switch the signal meter to show voice strength instead of 4g data strength. This worked great on my old EVO 4g LTE....but the Note 4 doesn't seem to have the same file structure and therefore I am unable to get this to work...any Devs out there what to look into this....That would be AWESOME!!!!

I have been using jio 4g for past 2yrs. The internet connection was good. But for the past 6 months I am facing frequent disconnection of the internet. So I go into flight mode activate and deactivate it again the net connection will be good for a minute and then it drops again to b/S. Frustrated I changed the SIM. But same problem. The bio customer care says it to update firmware! Which was not available and at last they told me to get the mobile serviced. So I swapped the SIM to another mobile and checked. There was no problem in that mobile. Please help me. Whether it is due to SIM or the band problem with mobile. I am using a stock firmware
Ps. Even I resetted, rooted
Set the network type or RAT or network mode to LTE (4G) only, then the phone should stay on the signal even when the signal is low for a second, around -120 rsrp (signal), specifically it should normally follow the parameters sent by the network: qRxLevMin (it is half the rsrp), qQualMin (sometimes, it is the signal quality), sNonIntraSearch, ThreshServingLow (both are ranges around qrxlevmin, one for entry threshservinghigh, one for exit). These parameters should nornally not be followed with LTE (4G) only. But only if the signal drops below the limit for a second. Else, it is a waste of resources, both for you (battery, etc), and the network, though the network can deprioritize cell edge (low signal) users.
To do so, there are extended network modes (for sim 1) in a menu that comes with Android, it is called 4636, Testing, Phone info, Device info, etc. There are apps that open 4636 without root, that offer: mode selections, lte only, anything cellular related that opens 4636.
Hold the phone on its top, not its bottom, for testing, the primary reception antenna should be at the bottom for A 2016, you can check this in *#0011#, it is "ant rsrp diff", it is positive when the primary reception antenna is better, negative when the diversity reception antenna is better, the diversity antenna should in most cases power on when the cellular is in use and start measurement, in contrast to the primary that's just switched on.
The signal can be measured in *#0011#, rssi is the signal strength of the frequency, the signal strength of intra freq (same frequency) neighbors (other cell towers etc) may differ slightly anyway because it's missing a decimal point; rsrp (good maybe at least -120, get it closer to -1) is approximately the signal strength of the cell, it is a few antennas in the long rectangular boxes on a cell tower, note that it is the measurement of the reference signal not the data that is being sent to your phone; rsrq(good maybe at least -15, best -1), sinr (good maybe at least 0, best 40), are signal quality. The "registered plmn" is the currently connected operator (mobile country code and mobile network code), if it changes (different compared to the sim), the signal is low! The "PCI" is the currently connected cell, note that there are only ~500 of these, so to identify the cell you can use both PCI and TAC (region), if the pci changes and the signal strength drops, well, the signal dropped and a reselection is made to an inferior cell, which can then drop data... in this case contact your mobile network operator but they might not make changes if it only affects a few users. You may try to lock band/etc to the good cell that sometimes drops in quality for a second but overall better than the neighbour cells.
Here's a short list of scenarios that can cause problems in connectivity, not all.
1: Low signal, plain old low signal. If the phone can't register VoLTE the bands that can be connected to may be restricted on some MNOs.
2. The antenna is closed and this causes low signal.
3. Low signal of the serving cell, the signal of an inferior neighbour cell matches (above parameters!), the phone changes to another antenna on a cell tower, quality drops and so does the connection. On another cell tower or there are 2 antennas on 1 cell tower, for example 1 facing the azimuth 180 degrees, another 270, the phone being in 215 degrees is unfortunate!
4. The antenna is open and receives interference (and reselections, sometimes good) from neighbour cells.
5. Good signal but it has been echoed a bit too much.
6. Reject causes and others, where the connection has been disconnected for some reason. Probably not in this case! It is viewable in *#9900# > Take cp log > copy to internal sdcard. It is in the /internal storage/log/LitmusLog. Scroll down to the reject cause section, those are error codes.
None of these codes/volte are working: The CSC is not applied correctly! Flash stock rom and open the stock recovery or copy /system/csc/...csc.../system/ to /system/etc/.
I do not recommend anything EFS/PIT, making a backup of efs is OK!
Hi,
I am facing the same problem with a7 2016 with JIO sim.
The mobile is purchased in dubai and when insert jio sim in india, was not able to use volte service.
So I flashed official indian rom. Everything is fine except net speed. Net speed between 1-5am is very fine but in day time speed reduces.
Everytime i have to restart data to use net but after a while same problem occurs.
Tried in both sim trays. I am using single sim in mobile.
Pls provide a solution.
Regards
