LONDON Iridium Satellite has appointed Cambridge Consultants as a strategic wireless technology development consultant to help it evolve the design of its ground-based terminal equipment. The consultancy has assembled a multi-disciplinary engineering team with expertise in satellite communications to work on the multi-million dollar program.
Cambridge Consultants is developing next-generation radio frequency (RF) hardware and software to enhance the functionality of Iridium terminals. The focus will be on moving much of the radio functionality into the digital domain using advanced digital signal processing (DSP) techniques. This will provide Iridium with greater performance and flexibility.
Cambridge Consultants is also adding features to Iridium's advanced packet-based data communications capability. These will extend the performance of the Iridium network in application areas such as supply chain management and remote monitoring. The new capabilities will appear on Iridium's forthcoming '9600' data modem.
In a recently completed 14-month development project Cambridge Consultants updated elements of the Iridium handset's RF, analog and digital circuitry, and provided a foundation for future enhancements.
