I was wondering if there is a way to manipulate the emulator to simulate telephony signal strength changes.
I would like to test code that uses TelephonyManager.listen() with LISTEN_SIGNAL_STRENGTHS.

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.
My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.
It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.
At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.
So, the my questions are...
Does the signal strength apply to the data signal or just the voice signal?
Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?
Is anyone else having signal strength and/or data service issues?
Should I exchange the Moment for another Moment or will I likely experience the same issue?
I'm writing an android application that collects cell signal strengths. I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths. To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback. It works, but not very well. It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers. I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better. The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths? It seems odd to me that the functionality of the neighboring cells is better than the current cell. Am I missing something here?I would also like to directly call a method from the telephony manager to get current cell strength, as opposed to a listener, if possible. If anyone knows how, please let me know.

View 7 Replies View RelatedI'm guessing that the GPS hardware in most Android phones is the same or close. If it makes a difference I have the Moto Cliq XT.I'm going hiking tomorrow and will be using Google's My Tracks program. I've tried it twice... the first time I could not get a signal despite being out in desert with nothing to block the signal. Next time I was in the mountains and once I had a signal, it was rock solid. Worked like a charm. But I did not want to take a chance and held it in my hand the entire time. I'm wondering if anyone has tried it while the phone was in their pocket. Any issues with sat lock on? This would be much easier. I also can't imagine that you'd not be able to use GPS while the phone was in your pocket as it's not really possible to have it in your hand all of the time.

something like: int signal = getPhoneSignal();
I am on Verizon network and was looking to get a Samsung Fascinate. I looked at the signal strength a 2 different stores, and both store Fascinate phones were about -10dBm higher than my 8320 Blackberry curve. Can I use this as signal comparison? Would I lose the ability to call in theory before the blackberry? I sometimes spend the weekend in a rural area where the signal strength is sometimes marginal on the blackberry at over -105 or so dBm is why I am asking.
View 3 Replies View RelatedI know that it's possible to determine the data connection type (WIFI/or cellular) through Android, but is it possible to determine the cellular connection type and strength?
I have an app that downloads some images and I have found that on GPRS or on 3G with weak signal that this download process slows up the app unacceptably. What I want to do is say that if you have either WIFI or a strong and fast data connection then download; otherwise display a default placeholder image.
I want to change the network signal strength programmatic-ally in android..Even though signal is full i want to make it 50% or even 0%. Friends is it possible..?
View 1 Replies View RelatedI am working on Android platform 2.1 and trying to make an app that can get the Bluetooth signal strength from remote devices. It seems i should try to read the 'RSSI'
something like : int rssi = intent.getIntExtra (BluetoothDevice.EXTRA_RSSI, Integer.MIN_VALUE);
But it just keep returning the latter default value.
Did anyone ever manage to get the value of RSSI? Do we need to pair the device before getting the RSSI?
I have some doubs about the Signal strength icon display as below:
1) Is it possible to change the signal strength icon?
2) Which is the API/method dealing with the icon updation in the status bar , based on the signal strength values received by the phone from the network?
I'm writing an app to monitor detailed radio data coming off the phone that I'm sending back to my own server that is collecting this information from a number of different devices. The purpose is to analyze the data from all devices, and generate a kind of "real-time network coverage" pattern.
The data I'm looking for is "Eb/No". From what I understand this is interchangeable with the term "Ec/Io". My first approach lead me to the new Signal Strength (http://developer.android.com/reference/ android/telephony/SignalStrength.html) support in Android 2.1. This is great, however you can only get Ec/Io values for "CDMA" and "EVDO" networks. My problem is that I'm on ATT, where I'm "WCDMA".
I was hoping Android would give me the "CDMA" values from Signal Strength changes (since "WCDMA" is somewhat similiar to "CDMA"), however the update has the gsm flag set to true, and it's giving me values for the gsm signal strength and gsm bit error rate instead.
For example, in my PhoneStateListener:

View 1 Replies View RelatedI am building an application reading the signal strength of each available WiFi access point. I've written code like:
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
// Get WiFi status
WifiInfo info = wifi.getConnectionInfo();
textStatus.append(" WiFi Status: " + info.toString());
// List available networks
List<WifiConfiguration> configs = wifi.getConfiguredNetworks();
However, I have two problems:
In debugging, configs only contains one connection. However, I can see that there are several APs available in the system's wifi setting. i.e. configs is an incomplete list. I don't know how to get the signal strength in Wifi Configuration. I am using HTC Hero and Android 1.5.
Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5?
I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value.
Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.
I need some clarification on API docs.
http://developer.android.com/reference/android/telephony/SignalStreng... getSignalStrength() indicates: "Get the GSM Signal Strength, valid values are (0-31, 99) as defined in TS 27.007 8.5"
[url] getRSSI() indicates "received signal strength or UNKNOWN_RSSI if unknown For GSM, it is in "asu" ranging from 0 to 31 (dBm = -113 + 2*asu) 0 means "-113 dBm or less" and 31 means "-51 dBm or greater" For UMTS, it is the Level index of CPICH RSCP defined in TS 25.125"
So, for 3G UMTS networks, does the SignalStrength class not return the same value as the NeighboringCellInfo class ? What are the chances that each RIL implementation is sending something different ?
Has anyone see negative value for signalStrength on UMTS networks as is possible for RSCP index values ?
I'm trying to determine location via bluetooth beacons and while I can discover and find all of the devices around me, when I try to grab the EXTRA_RSSI that's supposed to come through it doesn't work.
Here's the code I'm using and I get a 0 every time.

First I want to acheive battery status and signal strength instantly. For Battery Status, we can use SystemProperties.get ("status.battery.level_raw") to get current battery level. This class is not in SDK reference, but we can see this function is used in BatteryService and other fields. I use it successfully But for Signal Strength, I only find the way to use onSignalStrengthChange(int asu) which only gives us an "asu", new version seems to support onSignalStrengthsChange(....). But now, is there better ways for exact signal strength?
View 7 Replies View RelatedThere is a site Cellreception.com that tries to aggregate cell phone reception from users who bother to leave reviews. But data collection can be made much more easier, even passive:
Make an app that sends the phone's GPS location and the 2G/3G signal strength of the current provider in that location, to a centralized database, aggregate the results, and make them public online.
Nth Signal seems to be an app like that, but I can't find it on the market, and the reviews on Androlib are not good.
In an attempt to conserve my battery I've been switching between GPRS & 3G. I only switch 3G on when I need it e.g. browsing the web. Sometimes though, depending where I am, the GPRS signal is better than the 3G so I end up switching back. Is there an app that will show 3G signal strength?

This is my first Sprint phone so I don't know if it is the service or not. I came from ATT and never had these issues with my iPhone before. I am a little concerned about whether I exchange phone or am I going to just have to give up on Sprint.
