wifi

I need to understand how Wifi triangulation basically works. The scene is as portrayed in above diagram. Inorder to implement wifi triangulation, I need a minimum of 3 Wifi hotspots and their positions. The setup: 1. For simplicity, let's assume I have a 1 sq-Km by 1 sq-Km area, and I have 3 Wifi hotspots in this area. The coordinate system is as follows: 1 corner of the square area is (0,0,0), and the diagonally furthest corner will have coordinates (1,1,1). All position determination is to be done relative to this coordinate system alone (for simplicity, I don't want global xyz coordinates).

I was just wondering if it is possible to set up a data transfer tunnel between an iPhone and a Mac using the Wifi hardware present on both devices? My main objective is to transfer data from my iPhone to my Mac through an app along an ad hoc wifi connection. If there are any other methods you would like to suggest, then please do. Looking forward to your replies. Thanks! A.K. You can make use of Bonjour, via NSNetServices and CFNetServices APIs. Basically: Create a server on the Mac Announce the server via Bonjour Browse Bonjour on the phone and resolve the bonjour service. Establish

I have been running some testing with wifi proxy settings on a Motorola Xoom with Android 3.2. So first of all, it is a big step forward comparing to 2.x releases. now if you set proxy, most of the apps automatically get it (in 2.x, only builtin browser uses it). So I tried things like yahoo finance, bloomberg, etc. and they all going through proxy fine. What I don't get is some browsers like firefox, Opera, will not go through proxy. Any idea how they did that. Basically in my app, how can I decide if I want to use proxy or try to connect directly. Based on my testing, if we don't do anything

This is for a tweak , so the target is jailbroken devices, and not the app store. I have tried hooking different methods in the SBWiFiManager but they either are called when the wifi strength changes (so continuously) or after quite delay after the network has changed. Is there any other way to get a notification (or another method to hook) went the wifi network changes? I know you can get the current SSID with public APIs now, but I need to be told when it changes. Nate One way to do this is to listen for the com.apple.system.config.network_change event from the Core Foundation Darwin

I have to connect my app with server using either wifi (if it is available), or gprs (if wifi is not available). Here is my code to check the connection availability public static final boolean isConnectionAvailable(Activity a) { ConnectivityManager cm = (ConnectivityManager)a.getSystemService(Context.CONNECTIVITY_SERVICE); State mobile = cm.getNetworkInfo(0).getState(); State wifi = cm.getNetworkInfo(1).getState(); if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING) { return true; } if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State

I want to write an application that it can record the wifi hotspot's location we are accessing and display them in map. But the problem is - how do I get wifi hotspot's location? I think I can use the wifi signal to get the wifi hotspot's location, but it may not be very accuracy at first time. And if there is no other solution, I could record the location of GPS when access wifi hotspot at the first time. You'll not be able to find the hotspots location and you'll not be able to determine the direction and distance from your current position to the actual hotspot. The hotspots don't report

I am trying to connect to wifi through python and linux terminal but in both cases it is not working with me. For python, I am using this library https://wifi.readthedocs.org/en/latest/scanning.html scanning and saving the scheme is working fine but whenever I type this line of code scheme.activate() and I get no output Any ideas what is wrong with the library and if you have used it before or not?? I tried also to connect to WiFi networks using the CLI. I Googled and found that I should do these three statements 1- iwlist wlan0 scan // to scan the wireess networks 2- iwconfig wlan0 essid

I am trying to find out how I can list all of the available wireless networks in Python. I am using Windows 8.1. Is there a built-in function I can call, or through a library? Please kindly show me the code which prints the list. You'll want the subprocess module and a windows command: import subprocess results = subprocess.check_output(["netsh", "wlan", "show", "network"]) A little extra to just get SSID's. results = results.decode("ascii") # needed in python 3 results = results.replace("\r","") ls = results.split("\n") ls = ls[4:] ssids = [] x = 0 while x < len(ls): if x % 5 == 0: ssids

I want to transfer some data between PC and a mobile phone with WiFi. This is how I get the WiFi IP address: String ip = String.format( "%d.%d.%d.%d", (wifiInfo.getIpAddress() & 0xff), (wifiInfo.getIpAddress() >> 8 & 0xff), (wifiInfo.getIpAddress() >> 16 & 0xff), (wifiInfo.getIpAddress() >> 24 & 0xff)); new Recive().execute(ip); This is the code about sending a message to the PC: Socket socket = null; String message = "test\r\n"; protected Void doInBackground(String... urls) { try { Log.i("ip", urls[0]); socket = new Socket(urls[0], 2468); toserver = new DataOutputStream(socket.getOutputStream
