Detect Internet connection Speed

[Satheesh Kumar <satheeshrulzz@...>]

I am using Lua to develop a mobile appication.

Is there any function ( in lua sockets or other) to determine the speed of the device's internet connection?

Or should I just download a file and calculate (bytes/time)

I need to detect if the device's internet is 2G or not..
