Keep informed about picoChip
The Centaur physical layer (PHY) Centaur from Cambridge Consultants is a full GSM / GPRS / EDGE / E-EDGE (Release 7) Base Transceiver Station (BTS) Physical Layer (PHY) reference targeted at picoChip’s highly integrated baseband processors, and supported by a comprehensive test framework.
It enables manufacturers to very quickly develop extremely low-cost basestations, whether for residential femtocells or cost-sensitive macrocell applications.
It can be used to implement a GSM femtocell, either as a dedicated system or integrated with picoChip HSPA solutions, or as a fully featured picocell or microcell. The complete BTS has a small footprint so that, for example, and a number of modems can be implemented in a single PC203 to implement a powerful multi-channel basestation.
Cambridge Consultants can also provide support services to assist with the integration of the PHY into products.
