WiMax may be dead in the water, due to a lack of interest from the
service providers already -- in my humble opinion. The service
providers already in place, are doing point-to-point last-mile services
on 5.3 and 5.8 GHz and have a huge install base they won't want to drop.
Examples of the equipment they're using:
Trango Wireless, Motorola Canopy
Unless the manufacturers of those example systems above make a WiMax
product that inter-operates with the existing management tools for
managing subscriber units on those other widely-deployed systems, WiMax
doesn't stand a chance in anything but new deployments, because the
install base is fairly fixed in many areas now.
Of course, there will be plenty of new deployments... we'll see if they
can compete with the existing providers in areas that already have coverage.
Around here we're starting to see the "second stage" of wireless
broadband services. The little 802.11 companies are being eaten up by
the guys who did their RF equipment "right" with the 5.8 GHz equipment,
and point to point high-speed licensed microwave backbone links.
Their networks are being yanked out and replaced with these much more
I remember seeing early stuff where small companies were taking the
Lucent 802.11b routers and stuffing them in NEMA boxes -- but we haven't
seen those on towers around here in a couple of years.
The 5.8 GHz providers are using panel antennas and "sectorizing" their
sites, just like cellular.
