Wi-Max is Perfect...Theoretically

by Mark Evans on Tue 19 Apr 2005 03:27 PM EDT | Permanent Link

Perhaps the quote of the day from VON Canada comes from WaveRider Communications CEO Charles Brown who said that "Wi-Max is perfect because it doesn't exist". While having great promise, Rose argued there are still many challenges facing the technology as inter-operability issues, high equipment costs and inconsistent quality of service. I'm sure these are the words that Clearwire CEO Craig McCaw wants to hear given he's trying to build out a Wi-Max network in 100 U.S. cities. The sense I get about Wi-Max is there is plenty of excitement but it's not quite ready for prime time from a business perspective. As a result, demand for equipment has been stifled as businesses struggle to determine how to use Wi-Max and make money from it.

Alvarion seems to be trialing a lot of WiMAX-ready gear in Europe via Siemens/Alcatel OEMs.

It appears that WiMAX is a lower cost, higher bandwidth, packet oriented solution for wireless deployment that will give traditional microwave links a run for their money? Running on licensed frequency is a good thing.

Airspan is also doing something in Japan I believe... while only a press release for now, the intent was " The Yozan MetroZone will deliver high speed IP connectivity, and support Voice, Video and broadband data services. "

WiMax is also more suitable for anyone outside of North America. Outside of a few remote areas, the value of WiMax is limited. We have "Cable and "DSL." Building wireless data infrastructure in the US is sucidal. Look at Cometa. Look at the Paul Allen's WiFi investment, Metricom. Look at look at - what does it take to learn from our past?
