TTPCom has demonstrated an EDGE module capable of achieving the maximum on air data rate of 236.8kbit/s for a four-slot capable mobile.
The module uses the highest EDGE coding scheme, MSC-9, more than tripling data rates previously achievable with GPRS and elevating the standard for rates over GSM networks. It is suitable for the development of EDGE PC cards, PDAs, embedded modules and handsets and also enables field testing on live networks.
The module is based on TTPCom’s EDGE Protocol Stack and Physical Layer, running on Analog Devices’s Blackfin SoftFone EDGE platform and features link adaptation, incremental redundancy and EDGE coding schemes including 8PSK, all verified under interoperability testing. Modular design enables different radios to be supported and offers flexibility for developers. According to Greg Matthews, TTPCom EDGE product manager, it “fulfils the promise…in both transmit and receive,” of enhanced data rates for GSM evolution.
The system validation process has also included full integration and verification using TTPCom’s GPRS protocol stack, in order to ensure a seamless transition for existing customers.
The module is targeted at the increasing global adoption of EDGE, which is now being looked at as a serious option by some European, as well as US operators.
