[BAWUG] high latency on wireless links

[Paul Cox]

Hi,

Thinking the BAWUG group would have a great deal of experience in deploying all kinds of links with 802.11 products, I've searched the BAWUG archives looking for clues as to what kinds of latencies you have encountered.

The archives indicate that link layer retransmissions caused by faulty equipment or a low S/N ratio could cause the latency on a particular link to increase from a few milliseconds up to hundreds of milliseconds and perhaps beyond a full second. There's also mention that links in a heavily utilized mesh would also suffer from high latency.

I'm looking for confirmation of these conclusions from those that have first-hand experience with long-haul 802.11 links. I have been unable to locate a list of the links in the bay area along with the latency between nodes. If you could post your observations/data to the list it would be quite useful. Are those running links over huge distances or noisy environments seeing latencies in the hundreds of milliseconds or more?

Thanks,

Paul Cox
