We have used the 2.4GHz version of the Exalt radio - the EX-2.4i. We were fairly happy with it. The latency and jitter was great for a TDD radio, better than any I have seen. It was very reliable from a data-forwarding perspective. The management interface was nice when it worked, but the HTTP interface would lock up after extended periods of operation. We also got unusable values from some of the SNMP error/discard counters. In the end we took it out due to the need for more bandwidth and some issues with intermittent interference (to be expected in 2.4GHz). If the specs meet your needs then it would probably be a good solution.

The motorola PTP 600 seems thus far the most valid solution. We want to remain on ISM bands, because we don't want to take the burden of renewing the license with FCC every x years ... we need something that once installed requires the least maintenance effort possible. We already have antennas and cables that work with the 5.8 GHz spectrum. There's a distance of 3 miles between the two antennas and there's LOS available. The copper handoff could be solved with a media converter ... I am also proposed an Exalt EX-5i at 200 Mbps. Does anybody have this hardware installed and can share any experience had?

The Motorola PTP-600 has a 2000 byte MTU, but doesn't do multimode handoff. What radio to get will come down to what you are willing to give up -- if you are willing to drop the 5.8Ghz band and go with 11Ghz then the Dragonwave is for you -- the new Horizon Quantum is amazing (and pretty inexpensive when I priced it out) Bridgewave isn't bad either - you can get to 1.25Gbps with some fiber handoff.

The original solution wasaProxim Tsunami GX 200, but unfortunately it doesn't go beyond an MTU of 1536 bytes: we need at least 1544 bytes, ideally between 4470 and 9212 bytes MTU. The handoff should be MM fiber, the desired throughput 200 Mbps. Thanks, Stefano
