I'm looking into sat broadband access for a colleague. Does anyone
any experience of the performance of the 2 way systems. I'm interested
in the latency as this will be used for VPN access. What is the
ping time of somewhere like www.yahoo.com ?
Im not a satellite user but the laws of physics alone prevent you
ping less than about 280msec theoretical minimum. The reality is
far higher. It'll remain that way forever assuming einstein is correct
A two way system would be twice that surely, unless my maths has suffered
in this heat !
For each ping, data travels both ways then the return ACK travels both
ways. 4 x 22300 miles, I make that 89200, over half a second assuming
186000 miles per second in free space ?
