计算路由信号的功率或数量

Question

I need a function in C++ or Java to calculate the number and power of signals coming from Wifi base stations. This function will help me to find the difference between two positions, of a laptop.

( Note : i am so sorry about first questions , because i have bad english , and this Q came with translator with editing from me).

Answer 1

There is no portable function for that, because it differes HEAVILY across operating systems. In Linux, you can ioctl on the device file, on windows... no idea, sorry.

I think for these kind of questions, google is a good match - try searching for "wireless library java c++", or "c++ wifi strength", play around a bit.
