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.

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). On 4/24/10 8:05 PM, "Brad Belton" <[email protected]> wrote: > Agreed.
