Clearwire Demoed in SF
Posted by Sam Churchill on September 11th, 2008At the CTIA show in San Francisco this week, Clearwire installed four three-sector WiMax cell sites around the Moscone convention center for a 15-minute driving demo and pulled up Portland’s live traffic cameras.
Clearwire chairman Craig McCaw said that upstart WiMax operators can take on much larger rivals such as AT&T and Verizon Wireless due to their 2.6 GHz, reports Unstrung.
“The repurposing of 2.5GHz spectrum has given that opportunity to us, Don Quixote, to tilt at another set of windmills.”
Clearwire’s time division duplex (TDD) technology will allow “rich data” for users and spectral efficiency for the operator, McCaw says, as it uses one channel for broadcast, compared to two channel frequency division duplex (FDD) networks that are used today and will be carried over to long-term evolution (LTE) deployments.
“Why take up half your spectrum when you’re downloading a movie?” says he.
Sprint’s Dan Hesse also said open access will help Sprint cut the subsidies it pays on users’ devices. This has always been a big part of the reasoning behind Sprint’s XOHM WiMax network: Subsidies can get cut while prices fall as more device makers go broadband.
The show started with a well-attended keynote session, a discussion among cellular CEOs from Verizon Wireless, T-Mobile and Sprintas, as shown in this RCR News video.
