SDRs provide wireless communication components whose trans¬mit and receive characteristics are realized through specialized software running on programmable platforms. The benefit of allowing a single communications platform to be rapidly reconfigured for multiple, highly-diverse communication is to multiplex receive and transmission signals of different encodings on many frequencies (each combination is called a “waveform”). SDRs handle waveforms programmatically are used in fundamentally new ways for multiple domains (e.g. C4ISR, Internet of Things, Robotics, Space, etc.). Sup¬porting several waveforms inside the same device eases bug fixing, enables field re-configurability, allows mul¬tiple data transmission standards to be supported simultaneously, and helps improve the security and integrity of communications. Any communication task can be realized instanta¬neously by uploading/downloading appropriate software that defines the necessary waveforms allowing rapid reconfiguration and upgrades of Over-The-Air Reprogrammable deployed equipment and use of Smart Antennas. This webinar’s purpose is to provide background and solicit interest for a revised version of the OMG Software-Based Communications Domain Task Force (SBC/DTF), called the Secure Network Communications (SNC) for Software Defined Radios (SDR) Working Group (WG).
