Maybe someone can direct me to a previous post, but simply, I'm looking for the fastest wireless link I can set up (bridging). I have two LANs (separate buildings) that are 0.4 miles apart that I want to bridge together.
I've set up past links using Buffalo WHR-HP-G54s running Tomato Firmware. I get low latency with 25Mbps max of throughput (with semi- parabolic grid antennas - 24dBi). Given that Buffalo can't sell wireless equipment due to an injunction, I cannot go that route again. Besides, I'd like to go faster.
I've thought up some ideas on ways to leverage standard 802.11 equipment. Some thoughts:
- Channel bond A & G radios in a dual-radio bridge, such as the Cisco Aironet 1240 (no success there yet).
- Run two bridge links and bond the two links at each end with a capable switch (Cisco calls it "EtherChannel).
- Bridge with 802.11n (Draft 2.0). I understand that some of the new technologies of N still are effective in narrow focused beam configuration (24 dBi SPG antennas) over G. Maybe use antennas that have broader coverage if MIMO can be taken advantaged at that distance.
- Full-duplex (Not to spec, I know) / transmit on 1 antenna, receive on another (with difference polarization). Or use multiple radios, one that transmit on 5 ghz, but receives on 2.4 ghz (is that even possible?)
I'd like to hear of some (better) ideas, especially what has actually worked. I can probably spend a $1000 on each end for the radios if I can get better speeds.
Thanks,
Michael
