Re: [WISPA] making 5ghz link work with more power

Re: [WISPA] making 5ghz link work with more power
I realize that you state that you cannot go with any bigger antennas, but you might be able to fix this situation with the same size antennas if you go with a more focused beam. You state that you are running 24db panels. Panels generally have a pretty wide beam width. If you switch to a parabolic of similar size, you would probably gain at least 3db on each side of the link. - Larry -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Kurt Fankhauser Sent: Tuesday, March 16, 2010 8:49 AM To: 'WISPA General List' Subject: [WISPA] making 5ghz link work with more power Have a 5ghz 1mile backhaul, its near-LOS.

Re: [WISPA] making 5ghz link work with more power
Consider testing some mimo 'n' gear...such as ubiquiti ... you should be able to get the 60+mbps range you are looking for. You did not say how long is the link ? (we have 2 rocket m5 w/2ft dishes, on a 8.7 mile link, with not a clean LOS, the radios are turned down in power to 20dbm, 20mhz channel, (chain0=71-73dbm/chain1=70-74dbm), the wireless side is TX/RX = 117Mbps/117Mbps.. thruput testing shows 50+Mb/s). The only stickler would be that currently the dual-polarity antenna's are not quiet in the 24db range.. they have 2ft dishes, 29db Nanobridges 10inch dish (very narrow beamwidth). should be available in the US 30-60 days. or wait for the Powerbridge M (built 2x2 Mimo, dual polarity 24db pannel)... about 90-120 days.

Re: [WISPA] making 5ghz link work with more power
I have one 12 mile link running the new 27dbi AirGrids as a backhaul. My signal is -70 although I've been lazy and haven't fine tuned one end yet. I'm able to transfer a clean 70+ mb/s on the link. Both ends are 100 agl, one end is 60 feet lower than the other, lots of trees but still a good link. Dump the panels, go to a parabolic type antenna. The new dual polarity Ubiquiti dish is coming out soon, may be worth the effort to try them.
