Is it possible to connect without line of sight

[skone]

I have two buildings about 100 yards apart and I would like to connect them with a Ubiquiti product. The problem is I do not have line of sight. There is a brick house and some trees between them. Would I be wasting me time with a wireless solution or is there any chance I could get it to work? If so, what antenna would be my best bet?

Hello,

I cannot recommend our products for non-LOS operation. Many people have gotten them to work, but I cannot guarantee stability.

Thanks,

I would try with par of Loco 2 13 dBi internal antenna radiosradios. There aren't all that powerful, but they are very inexpensive. If you can at least get a -90 dBm signal, then I'd move up to a $150 PowerStation 2 with 17 dBi internal antenna radio and that will 16 dB to your path. So if the Locos get you -90, then the PS2 will get you -74 dBm.

Has anyone been able to get this to work in a similiar scenario?

I have 2 Nanostation 2's setup with non-LOS, going about 2500 feet, one is zip tied in a laundry room inside my sisters house, the other is hanging on my parents deck :D... There is a large hill in the way and I can barely see the top of my sisters roof from where the Nano sits. Also a large oak tree in the way... Working flawlessy for over 6 months now.

Everybody is rightfully touchy when NLOS is mentioned.... but if you are <1mile you may be impressed with the Ubiquiti gear and what it can go through.

That said, there is not a good way to know unless you just buy the equipment and try since every situation is different.

Mike,

will be that one day, ubiquiti sold NLOS/Wimax-like AP/CPE equipment?

Uhh, propagation is a characteristic of the frequency, not MAC layer protocol.

The difference between WiMax and older systems is that it gives you OFDM, which can equal better propagation because it can turn multipath signals into better signal strength. Of course, 802.11a/g/n are OFDM systems too.

You could use a large brick building as a reflector dish in 3.65ghz. I've seen someone get 5dB better gain over their integrated antenna that way - by turning it around in the opposite direction of the tower, bouncing off a large brick building. I wonder what the FCC regs are on pointing your gear the wrong way are ?

Its the other way around. ODFM rejects multipath signals, "N" uses them.

802.11a /g ODFM is more robust than 802.11b PSK because it has a guard interval to deal with time spreading and to eliminate intersymbol interference (usually caused by multi-path propagation).

802.11n actually takes advantage of that interference and uses the multi-path propagation garbage to add to the base line signal.

I went to an island for vacation this summer. It had that, and I was glad just so I could check on my network LOL.. No towers, no cell coverage, but BPL was awsome to have available. I'm sure not a magic charm, I'm just saying it was nice.

Hold on....Let me duct tape the BPL coffin to make usre it don't open again.
