AT&T’s CTO talks here about the company’s broadband wireless trial in New Jersey: The network will use an early version of Intel’s WiMax chip but will use the official Rosedale chip later in the year.
He sounds about as confused about where WiMax fits among other wireless technologies as just about everyone else in the industry. He draws a comparison to the cellular world, saying that 802.16 has the potential to be a worldwide standard where such a worldwide standard doesn’t exist in cellular because of both CDMA and GSM. While it’s true that 802.16 has the potential to position OFDM as a worldwide air interface standard, a very significant roadblock is the lack of a common frequency to deploy WiMax in around the globe. That means that global roaming, which wouldn’t happen until the next version of the standard is available anyway, is very far away.
He’s very wishy washy on the topic of WiMax competing against 3G and seems to contradict himself. But at this stage in the development of the next WiMax standard, it’s pretty hard to predict how the technology will be positioned in the market.
