The Software Defined Radio (SDR) Forum has extended to Feb. 23, 2005, the deadline for comments pertaining to a request for information (RFI) the group issued in November. The RFI, issued by the Forum's Public-Safety Special Interest Group, seeks specific ideas regarding how SDR technology can meet public-safety interoperability requirements.

Among the things the Forum hopes to learn is how to leverage the investment the military has made in its Joint Tactical Radio Systems (JTRS) program, which was created to help the armed forces migrate from their current radio systems to SDR. While many of the military's requirements are shared by public safety, there are many others that are superfluous and would result in form factors and price points that would keep SDR beyond public safety's reach.

The deadline was extended because several organizations that expressed interest in submitting responses couldn’t meet the original Dec. 15, 2004, deadline. “The SIG decided it was important to include these responses and made the extension,” said SDR Forum spokesman Ken Zeszutko.
