Re: [WISPA] STP for redundancy on two panels horiz/vert oriented?
That really only makes sense if the links will have asymetrical bandwidth shaping otherwise you are just wasting capacity. Run them in parallel and load balance them or use the second as a backup. And DP antennas would be a cost effective way to go and would guarantee polarity isolation. Balance the RSL levels on both links and you should be able to operate on the same channel depending on the radio's C/I ratio Bob Sent from my Verizon Wireless BlackBerry -Original Message- From: Andrew MacLeod Date: Sun, 12 Apr 2009 16:45:08 To: WISPA General List Subject: Re: [WISPA] STP for redundancy on two panels horiz/vert oriented? I would concur with Josh. I would use OSPF and run the links unidirectionally that way in essence you get a full duplex link, but still have redundancy should a link go down. Also, why use two antennas? MTI makes a nice dual polarized 23 dbi antenna.

Re: [WISPA] STP for redundancy on two panels horiz/vert oriented?
I would suggest OSPF bridging so you can use both of them as long as they're working, if not then it just uses one.
