Latency depends mainly on the modulation scheme, as it does on cable and
DSL.
Packet loss, unfortunately, is more common than not and is directly
related to
oversubscription. I was lucky in that both systems I used (a local ISP
using
Canopy as well as ClearWire when they first moved in) were not
oversubscribed
and I rarely encountered packet loss though my speed would vary quite a
bit.
The Canopy was real nice because it was sold as a business service so
day speeds
were bad but at night I was pretty much the only person on the segment
so I would
get over 2 megs/second down AND up!
Hmm.. My experience with Canopy is that its rock solid day or night. The way it works each subscriber has a guaranteed time slice to transmit their data so the amount of traffic hitting the AP shouldn't degrade an individual subscriber.
