A UK outfit PicoChip has released a chip designed to form the baseband for public-access femtocells. The PC333 supports 32 channels of simultaneous voice and HSPA+ data, MIMO antenna scheme, soft handover and the Local Area Basestation (LABS) standard.
So far PicoChip's chips, the PC302 and PC312 are suited to residential systems, the PC333 has been designed for small basestations at urban hot-spots, city-centers or public access. It can manage 120-kph mobility and +24-dBm output power for greater than 2-km range.
The PC333 can support 32 channels and more than 400 smart phone users at the same time. Two of the devices can also be cascaded to support 64 active channels.
It uses a 65-nm process technology is due to sample to some customers in the next quarter. No word on price yet.
