I was reading about WiMAX networks and how they can provide a 30mbit connection to a user 50km away!
Now, I don't have a great understanding of data transfer but I assume inverse power law applies??
Pf = Pi / 4*pi*r^2
At 50km
Pf = Pi / 10^10 * pi
For Pf = 30mbit/sec = 30*10^6
Pi must equal:
30*10^6 * 10^10 * pi = 10^18 bits/sec = 1 EXAbit/sec
Really?! Can they transmit an EXAbit of data per second? How the hell do these things work?!
