Hello Adam,

Good information to know.  Yes, our experience with VL was some time
ago...well before 5.5.26 for sure!  

I can't believe I'm saying this, but we may have an application for a VL
deployment in a desert at some point.  We're looking for a PtMP system with
AES256 and I'm pretty sure VL has it.  Not sure if there are any other PtMP
products out there with AES256, but if a vendor reads this and has such a
critter feel free to send me information off list.

Best,



Brad

Hi Brad,
Alvarion firmware 5.5.26 and above have some decent mechanisms to deal with
noise and flooded RF environments. However, the clients need to have a
decent receive level (roughly -65 or better) if the noise floor is higher
than -90 in order to keep traffic flowing decently. There are a couple other
mechanisms internally to the radio such as Noise Immunity controls and a few
others. 5.5 and above is almost a requirement when running Alvarion VL
equipment. Anything below 5.5 doesn't show noise floor or RSSI (they only
show SNR, which is just weird).
