I agree with Josh H POL is a must on 900

What does your noise floor look like? C/I?
Have you tried moving from H-pol to V-pol and vice versa?
Could it be self interference (which I think might be the biggest problem
with 900MHz, at least the possibility of it)?
What type of antennas are you using... can you sectorize further or put
higher gain antennas at the clients?
Can you add filters possibly to help with the noise?
How large are your channels? Can you use a smaller channel?
Assuming your sectors are not overloaded... I would assume interference too.
Now I would pitch Canopy... but I'm sure you don't want to hear that :-D

Subject: [WISPA] Tranzeo 900 Latency
We have a couple of sectors of 900 MHz Tranzeo which were running fine
previously but seem to experience enormous latency at times now. I am
talking about upwards of 5000 milliseconds (5 full seconds) for a return
on
a ping. It is intermittent. I am guessing interference but was wondering
if
anyone had seen anything else cause this. We have had limited success in
dealing with interference in 900 MHz previously so we are hoping there
is
something else we can try before completely bailing on the band in those
locations. Any ideas are appreciated.
