The Dragonwave would be my first choice too, but they are not in the 5.8GHz band.
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
We love the PTP600 platform and it works very well for our needs - as good as any path profile has shown us. Depending on the height of the tower, you can handoff via copper or via multimode fiber (someone said it doesn't do multimode, we do it all the time with their "fiber kits" from Motorola). In all of our installs we use multimode and if the tower is short enough use cat5 as a backup connection. I'm not 100% on the MTU size but I'm pretty sure it supports at least "mini-jumbo". We are going to be pushing MPLS type traffic carrying VPLS paths across PTP600's this year and when we looked at any challenges we didn't find any on the surface....

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?

Bridgewave isn't bad either - you can get to 1.25Gbps with some fiber handoff.

Hi All,
I need a wireless bridge solution that allows to pass jumbo frames over a distance of 3 miles, using the 5.8 GHz band. The original solution was a Proxim 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
