SOFTWARE DEFINED RADIO
NEW TECHNOLOGY USING SOFTWARE (COMPUTERS), RATHER THAN HARDWARE FOR TRANSMITTERS AND RECEIVERS TO CHANGE OPERATING PARAMETERS, INCLUDING FREQUENCY, MODULATION, AND POWER
RADIOS QUICKLY CHANGE TRANSMIT FREQUENCIES AND FORMAT
DESIGNED TO ALLEVIATE POTENTIAL SPECTRUM SHORTAGE AND SPUR MORE EFFICIENT USE OF BANDWIDTH
WILL ASSIST INTEROPERABILITY, PARTICULARLY FOR PUBLIC SAFETY AND BETWEEN FEDERAL AND LOCAL OFFICIALS
