Reconfigurable Terminals for SDR

SDR in the handset
Perhaps the most significant issue wireless-system manufacturers face is the lack of compatibility in worldwide communications standards. The lack of a universal standard requires handset manufacturers to produce multiple models with differing electronics and programming for each standard. For users, the lack of commonality means that a handset probably won't work if you are traveling internationally.
Software-defined radio has the opportunity to address these problems. SDR is used to describe wireless handset systems that provide software control of a variety of modulation techniques, band operation, communications security functions, and waveform requirements of current and evolving standards over a broad frequency range. SDR handsets can be dynamically programmed to reconfigure operations for better performance, richer feature sets, new services to the end user and new business for the service provider.
SDR handsets require an operating system that can be scal...
