Description of original award (Fiscal Year 2005, $419,995)

Virginia Tech's Center for Wireless Telecommunications, in collaboration with Science Applications International Corporation (SAIC) and Innovative Wireless Technologies (IWT), propose to develop a software cognitive engine for public safety applications that will turn any frequency and modulation capable software defined radio into a public safety cognitive radio (PSCR). The cognitive engine will respond to the commands of a properly authenticated operator by configuring the radio for whatever combinations of waveform, protocol, operating environment, channel conditions, link performance, etc., and adjust the radio's settings to deliver the needed quality of service subject to an appropriate combination of user requirements, operational limitations, and regulatory constraints.

The work that the grantee is continuing from FY2005 will extend their development of a cognitive engine that can be used with software defined radios. Further research will be conducted and collaborated with law enforcement agencies. Also some work with developing antennas for a multi-band radio will be completed.


The applicant will continue work on developing a cognitive engine (CE) for a software defined radio. Working with the Virginia Tech Police Department (PD) and the Blacksburg PD, the applicant will further enhance capabilities of the CE. The CE has the capability to enhance a land mobile radio to identify which frequency band it is in, which will allow a law enforcement officer to communicate in an area outside of their radio footprint.
