Airvana not so down with UMB
You know the ultra mobile broadband (UMB), the proposed 4G path for CDMA EV-DO technology, is in question when one of CDMA's biggest backers has its doubts about the prospects for the technology. Airvana, which has historically pushed the envelop on getting the next iteration of CDMA2000 out the door, told Unstrung that it's too early to say what technology will be adopted by operators for mobile broadband, but UMB's future looks fuzzy.
"It feels like the world seems to be moving to LTE, and Sprint has gone with WiMAX for now," Airvana CEO Randy Battat said. "We're not sure what the opportunity will be for UMB. We're less zealous about that than you might expect from the CDMA camp."
CDMA has always held the advantage when it comes to getting higher speed data networks out the door. But the move to 4G is essentially a clean slate for everyone since it's a jump to OFDMA-based networks. WiMAX now has the first-mover advantage and LTE looks to have the economies of scale advantage since it's the GSM migration path.
With Sprint moving to WiMAX, it appears the success of the technology rests on Verizon Wireless' shoulders, and it hasn't decided its path. The chances are high that LTE is the choice since Vodafone and Verizon plan on using the same technology for their 4G networks. We know Vodafone won't flip to UMB, so the choice is between WiMAX (now a 3G standard)--which can be used in the near term to stave off competitive threats--and LTE.
For Verizon, it all drills down to performance, CEO Lowell McAdam said in an interview published this week in sister publication FierceWireless. "The suppliers of that technology would love to get you to declare early on. My view is whether it's WiMAX, Rev. C or LTE, you make the visionaries deliver something," he said. "You evaluate what they deliver and then you decide what fits best in your network ... Technology is technology. There's no emotion about it. Let's see how it performs."
Indeed, a lot can happen before 2010, but vendors need to make the right bets now.--Lynnette

Makes some sense to see Verizon Wireless opting for a 700Mhz based WiMAX system as their new 4G play, assuming of course they can beat Google out of the 700Mhz C Block. With the emerging Beamforming/MIMO smart antenna systems the new technology will dominate the last mile broadband deliver markets.
Just can't imagine them using the 700Mhz to enhance their Narrowband Cell (CDMA based)Network when they can jump out quick with a 700Mhz Broadand Network. They own the Backhaul (their FIOS IP network), the towers, the Biling systems and have the customer base to market to. They will need something to compete with AT&T plans for their 700Mhz network (Aloha Purchase of the Lower Band C Block and bidding on the Lower Band A & B Block spectrum providing them a Nationwide 700Mhz License play.
Sprint/Clearwire may be first to market but they will be handicapped by their reliance on the 2.5Ghz Spectrum (questionable coverage in heavy foliage markets).
