LONDON Femtocell pioneer ip.access is likely to be the first to market with a high capacity device for enterprise use that integrates picoChip's picoXcell PC312 SoC.
The PC312 HSPA+ femtocell SoC will support eight users, with simultaneous voice and data services, offering 64QAM modulation and 3GPP Release 7 features.
"At ip.access we are dedicated to solving in-building access problems for mobile operators," said Steve Mallinson, CEO of ip.access (Cambridge, England).
The PC302, the first in the picoXcell range from picoChip (Bath, England), that targets residential femtocells, is already shipping in volume. Earlier this year, picoChip said another femtocell developer, Ubiquisys (Swindon, England), will use the part.
The PC312 is pin-compatible with the four-user picoXcell PC302. This feature, allied with low power consumption that eliminates the need for a heatsink, allows manufacturers to develop a range of residential and enterprise products that offer low cost, low power, small size and high performance.
The new device builds on picoChip's field-proven modems, including the existing PC8219 eight-user solution, launched earlier this year with the backing of two major players in the femtocell market.
picoChip says its designs are incorporated in products that are involved in some 40 field trials of femtocells amongst 20 carriers.
The latest device integrates added features such as security and timing, and satisfies the new functionality requirements of 3GPP Release 8 for a Home NodeB. The PC312 supports the Femto Forum standard FRMI interface, and includes a glueless interface to many radios, including those from Maxim, ADI, Lime Microsystems and Bitwave, among others.
The device can support up to 21Mbit/s HSDPA together with 5.7Mbps HSUPA on a single chip that integrates PHY, RNC stack, synchronization, network listen and Radio Resource Management functions.
It includes a 3GPP NodeB modem, ARM11 processor, cryptographic engine, high-speed accelerators, and peripherals to support HSPA+ FAP requirements.
The SoC integrates all of the baseband processing requirements from digital samples to and from RF, through to network interfacing, enabling a very low system bill of materials cost and component count.
