"Software Defined Radio" solution for GSM/EDGE base-stations

Octasic announced its first Software Defined Radio (SDR) platform for GSM, EDGE and EDGE Evolution Base Transceiver Station (BTS) applications. Vocallo BTS is the first product of Octasic's wireless program that uses its Digital Signal Processing (DSP) technology.
True SDR capability enables mobile communications system implementers to dynamically reconfigure and upgrade wireless systems purely on a software basis. This has benefits, including cost of ownership, ability to respond quickly to changing market dynamics, such as the introduction of EDGE Evolution, lower development costs, and a time-to-market advantage.

The Vocallo BTS Digital Signal Processor integrates a Layer 1 base-band for up to 12 GSM carriers or 6 EDGE carriers or any combination. All this is achieved by consuming less than 1W (or 80 mW per carrier). Vocallo BTS' power density figure is a direct result of Opus, Octasic's asynchronous DSP core technology. Elimination of the clock tree also brings benefits in chip size.
The product is supported by the company's graphical Integrated Development Environment, which provides the product with a full suite of Layer 1 GSM, GPRS and EDGE modules. These modules are available as a 3 GPP compliant, source code reference library. Demonstrating both the efficiency of the toolset and the control capability of the DSP, reduced Layer 2 and Layer 3 code also runs on Vocallo BTS.
