wireless

I want to get signal strength of this wifi which is connected with my device. This is probably easy. But I am beginner. And It's homework. How to get it? I tried this code. But it doesn't work. registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { final WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); int state = wifi.getWifiState(); if(state == WifiManager.WIFI_STATE_ENABLED) { List<ScanResult> results = wifi.getScanResults(); for (ScanResult result : results) { if(result.BSSID.equals(wifi.getConnectionInfo()

I want to write a real-time analysis tool for wireless traffic. Does anyone know how to read from a promiscuous (or sniffing) device in C? I know that you need to have root access to do it. I was wondering if anyone knows what functions are necessary to do this. Normal sockets don't seem to make sense here. DGentry On Linux you use a PF_PACKET socket to read data from a raw device, such as an ethernet interface running in promiscuous mode: s = socket(PF_PACKET, SOCK_RAW, htons(ETH_P_ALL)) This will send copies of every packet received up to your socket. It is quite likely that you don't really

I'm developing a simple application for the Google Android to turn on and off the wifi or 3g or 2g. I see http://developer.android.com/reference/android/net/wifi/WifiManager.html#isWifiEnabled() that you can see if the wifi is enabled or disabled and also us http://developer.android.com/reference/android/net/wifi/WifiManager.html#setWifiEnabled(boolean) to turn on and off the wifi. I'm wondering if it's possible to do the same for 3G and for 2G/GPRS? I know it's possible because you can turn off 3G and left 2G on. 2G/3G To determine your network type use: TelephonyManager.getNetworkType();

Hello we have developed our first enterprise app recently. We are using the "In-House" option to create the distribution certificate. Client is not using the app yet. But he will be using it soon. Meanwhile i got a question. He will use the app and in future if there are any updates to the app from our side, we want the client to have it updated on his side as well . Like right now I have apps installed on my iPhone. I get update from AppStore saying the XYZ app has been updated. So i install the update. Now if our client is using the app and has saved some data on it(our app uses core data,

What would be the best way to triangulate a wireless network passively. Are there tools available? Algorithms? Libraries? My goal would be to create a relative map of various objects that sends or receive signals using signal strength (DB's), signal/noise ratio, signal phase, etc. from a few location points. With enough sampling, i'm guessing it would be possible to create a good 2d/3d map. I'm searching for stuff in any language / platform. Some keywords: wi-fi site survey, visualization, coverage, location, positioning Thinking about using kismet to gather the data and then process it. Maybe
