Picochip, the leader in femtocell SoCs, already has products based on its architecture in operator trials in the metro network. VP of marketing Rupert Baines pointed out that there is a basic difference of approach that will drive different economics for the dedicated femto designs compared to the TI approach, coming down from the macrocell. Picochip, Broadcom and Qualcomm (and in LTE Mindspeed and DesignArt) are "all emphasizing complete solutions, optimized silicon and bundled PHY software," he commented. "TI and Freescale are selling DSPs. They may be somewhat focused, but they are general purpose. They talk about software, but it is nothing like the investment that we or Qualcomm talk about when we talk about software."
This benefits a firm like Ubiquisys, which has its own software to offer partners, but many firms, Baines believes, will be looking for a full solution. He also argues that the femto specialists "get economies of scale from residential, that funds the variants for outdoor / public access - here I think TI and Freescale will have trouble."
Ubiquisys' small base stations will ship in the early part of 2012. They can be mounted on walls or street furniture in metrozones or public spaces, and promise performance of up to 150Mbps in LTE, or 64 calls/84Mbps in W-CDMA. They will use SON techniques to work with the existing macro network and will use commodity internet connections to reach the mobile core.
"Our infrastructure SoCs, based on our unique KeyStone multicore architecture, set new standards in combining processing power, economics and system energy savings," said Brian Glinsman, TI's general manager of communications infrastructure, in a statement. "Through our collaboration with Ubiquisys we are creating the blueprint for the small cell revolution."
