Re: Motorola: WiMAX not good for backhaul
"The reason, Mitoraj asserted, is that while WiMax was "built to do everything well," including diverse applications such as voice, video, and data, it is less effective when used for a single high-throughput application such as backhaul."
Less effective than what? How much "less effective"? Is it a show-stopper, or simply the RF cost of doing business?
"Motorola last year acquired a startup company called Orthogon Systems, a provider of fixed point-to-point wireless systems in the 5.8-GHz frequency band, largely to beef up its backhaul portfolio."
P2P, FSO, etc are obvious alternatives. At what additional cost (and gain) vs. using the WiMax network itself for backhaul?
"'WiMax will fail without dual-mode devices' that work over existing cellular networks or Wi-Fi systems plus WiMax, Mitoraj stated.
That will require the major U.S. carriers, who to date have focused on preserving their existing cellular business at the expense of newer wireless technologies, to open up their handsets and networks to WiMax."
Yup.
