wifi

Does anyone know how to determine the active network type at the specific moment: 2G , 3G or WiFi . For example, at a specific moment there could be enabled 3G , but the used network type could be 2G . The SCNetworkReachability interface can help you with that. Basically, you create a so-called reachability reference and then call SCNetworkReachabilityGetFlags on it to get information about the connection. The returned flags include kSCNetworkReachabilityFlagsIsWWAN , which tells you whether you are connected via WiFi or the cell network. AFAIK it cannot be used to tell the difference between

This is what I would like to do : => IF WiFi is enabled AND active, launch an intent (in fact it's a WebView that gets its content=>the instructions of my app on the web) => IF NOT, then I would launch another intent so that I don't show a WebView with "Web page not available ... The Web page at http://www.mywebsite.com might be temporarily down or it may have moved ..." I tought initially to use if(wifi.isWifiEnabled()) but that does not say if the Wifi connection is ACTIVE or not. It says only that the user has turned the switch on. The device may or may not be connected... Is this correct ?

my app accesses the internet and i just want to detect whether there is a connection either via wifi or via carrier data network or not apple has made an example for that "Reachability" https://developer.apple.com/iphone/library/samplecode/Reachability/ i think it just detects the wifi and not the carrier network can anyone tell me, whats the best to be done to detect if there's a connection ( any type of connection ) Appreciate ur help! That sample is exactly what you need. Look at Reachability.m. it'll tell you whether you have any connection, and then tell you what kind of connection you

In the android application that I'm designing, my service only needs to be running when the device is connected to the router (via WiFi obviously). I'm really new to android, and what I've got so far has taken me forever to Achieve, so I'm really hoping for some pointers. My service is set to start up when the phone starts up. Also when the Activity is launched it checks whether the service is running - and if not it starts it. I'm just wondering what code I can put into my service to make it turn off if the WiFi state is lost - and what code I need to make the service start once a WiFi

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
