Learn about SDR
With the exponential growth in the ways and means by which people need to communicate—by data communications, voice communications, video communications, broadcast messaging, command and control communications, or emergency response communications—modifying radio devices easily and cost-effectively has become business critical.
Software defined radio (SDR) technology brings the flexibility, cost efficiency, and power to drive communications forward, with wide-reaching benefits realized by service providers and product developers through to end users.
SDR is a communications device that uses software and hardware that can be programmed and adapted to the environment in which they need to operate. The use of SDR technology allows new wireless features and capabilities to be added to existing radio systems without requiring new hardware.
