I take it by spatial diversity you’re meaning traditional FDD frequency diversity, versus antenna physical spatial separation.
Matt, The B5 allows two frequencies to be used that are split anywhere between U-NII-1 up through the U-NII 3, but it runs TDMA on both frequency sets (not separated TX/RX). So technically speaking there is TX/RX going on in both frequencies actively, and the payload is load balanced across them automatically (it looks like one IP link to your network at all times). The nice advantage to a TDMA based frequency diversity approach, is that when interference comes on any portion or the entirety of one of the two frequencies, we’re able to keep operating on the clean frequency TX/RX and continue to adapt and re-establish the secondary channel (or drop the channel if that’s your preference). One feature we added, assuming you want to run in our auto modes (entirely up to you how automatic or manual the radios operate), both sides live exchange and coordinate their constant spectrum scanning info to pick channels that work for both sides cleanly (to avoid picking channels that the other side cannot support). Regarding antenna movement, individual polarizations should continue to operate during a signal fading on the other one as well as benefiting from the dual frequencies, so it should observe similar functions in that regard so long as you’re within the beamwidth of swaying. Also helps that it’s a very compact shielded antenna and radome for it’s 25 dBi gain spec. Cheers!

The primary reason, is the ability to have split TX/RX frequencies. Due to competitors, we cannot always find the same clear channel on two sides of a link. Does Mimosa support this? Also, we deploy in locations where the antennas move, sometimes a lot. The PTP series works very well with spatial diversity to improve performance during constant signal fading on one polarity then the other. How does Mimosa's products handle this? _______________________________________________ Wireless mailing list Wireless@wispa.org<mailto:Wireless@wispa.org> http://lists.wispa.org/mailman/listinfo/wireless
