AlcaLu CTO calls for new basestation chips

CUPERTINO, Calif. – Tomorrow’s wireless networks need chips designed mainly for a new class of small-cell basestations that will serve the growing capacity needs of mobile data users. But just where the money needed to build the new networks will come from is unclear.

That was the message Marcus Weldon, chief technology officer at Alcatel-Lucent, delivered to several hundred processor designers at the annual Hot Chips conference here.

“We are in a radical transition to a capacity-driven world served by Wi-Fi and small cells and away from a coverage world” using macro cellular basestations, Weldon said. “All the new chip set designs will have a focus on metro cells with a smaller emphasis on macro cells,” he said.

“Small cells are the only way to get 80-fold factor in additional capacity that will be needed,” he added.

Weldon predicted as many as 500 million tablet computers will be sold each year by 2017. They will, along with the rise in smartphones, drive the 80-fold increase in mobile data next-generation wireless networks will need to serve.

The needs are rising at a time when carrier’s data revenues are relatively flat and their voice revenues are falling. He suggested carriers will look for ways to charge per connection and per service, especially for new ways of shifting into the digital realm traditional “analog” jobs in banking, health care and other domains.

“We are in a staring match between content and network people where no one has figured out the model to build the network with the money in the pot,” said Weldon, pictured below. “It’s the entire digital economy wallet we should look at,” he said.
