Public Safety Communications

In public safety communications digital radios using Software Defined Radio (SDR) technologies including data communications such as maps and video are increasingly taking over from older analog technology radios. This is because of a number of factors:

  • Interoperability is the major driver which is cited by public safety agencies, when they specify new radio systems. The historical fragmentation of different public safety radio systems for police, fire, highway patrol, ambulance and other emergency services often makes for a nightmare scenario for inter-agency communication, as demonstrated by events such as September 11, 2001. As a result programs such as Project 25 and TETRA were initiated to drive improved interoperability into field radios.
  • Congestion in communications is another major driver for SDR technology adoption in public safety radios. In highly impacted radio scenarios, the equipment needs to be able to adapt to ease congestion.
  • Reconfigurability is seen as being key for public safety agencies who are looking for reconfigurability to add new services. Most players recognize that the future will bring new data applications into the public safety arena, but nobody can predict exactly how the data will be used. As a result, public safety agencies desire a radio which is reconfigurable and future-proofed.

New public safety radio equipment sold in the marketplace (both in terms of base station infrastructure and field radios) is very rapidly adopting SDR technology. A typical public safety radio utilizes programmable baseband processing, which includes channel encoding/decoding, modulation and demodulation, as well as encryption and other functions.
