RE: Wireless Ethernet bridge

["Paul Stewart" <pstewart () nexicomgroup net>]

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....

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?

Thanks
