  1. Agenda Item: 5.8 Software Defined Radio (SDR) and its Application to PPDR Communications ISACC

  2. PPDR Communications • Interoperability is a continuing challenge for PPDR Communications: • Security • Flexibility • Connectivity (mobile and fixed access) • New Applications • Sharing of infrastructure • Bandwidth

  3. SDR • *Software defined radio (SDR): A radio in which the RF operating parameters including but not limited to frequency range, modulation type, or output power can be set or altered by software, and/or the technique by which this is achieved • Radio functionality previously confined to fixed hardware implementations, continues to migrate towards software reprogrammable radios, which can be reconfigured to adapt to changing communications protocols and frequency bands • Evolution to SDR will have effect on spectrum efficiency, utilization and allocation in general • Impacts of SDR in military systems, emergency response, medical imagery, automobile sensors, commercial wireless systems and more • Many aspects of SDR, including detailed technical specifications for software download to wireless devices, are being developed by the ITU-R and other standards forums *Current ITU-R definition in Working Parties 8A and 8F

  4. SDR and PPDR • SDR can facilitate interoperability in several ways. • Bridging between air interfaces, RF bands and group affiliations • User enabled equipment according to specific requirements • Device reconfiguration to enable overlays and smooth legacy upgrades on existing systems without disruption • May reduce cost to public-safety wireless systems such as maintenance costs and cost to upgrade • SDR can lower total cost of ownership of public-safety wireless communications while also improving system responsiveness to interoperability issues

  5. ITU-R • Studies on the use of SDR technology and it’s applications to PPDR are being conducted in the ITU-R • WP 8A • Application and implications of SDR to land mobile systems, including public protection and disaster relief • Issues on efficient use of spectrum using SDR techniques, frequency sharing issues relating to SDR and general technical issues • WP 8F • Increasing use and implementation of software in a radio network and terminal and the potential implications to the future development of IMT‑2000 and systems beyond IMT-2000 • High-level technical aspects such as the latest areas of research and the state of technology development. Market aspects are also considered • ITU-R cooperating with other forums to enhance the work on SDR

  6. SDR-Forum (SDRF) • The SDRF Special Interest Group on Public Safety • developing report “SDR Technology for Public Safety” for September 2005 • based on responses to RFI “How SDR Technology Can Meet Public Safety Communications and Interoperability Requirements” • Developing ‘SDR public safety strategy plan’ - includes the potential business case for SDR within the public safety community

  7. New Canadian Initiatives on Public Safety • Public Safety Communications at 700 MHz • Broadband Public Safety at 4.9 GHz • http://strategis.ic.gc.ca/epic/internet/insmt-gst.nsf/en/home

  8. Public Safety Communications at 700 MHz • Canada has designated new spectrum for emergency first responders at 764-770/794-800 MHz • October 2004: Designation of spectrum for public safety and further consultation on technical and licensing considerations • this is the 2nd frequency band designated for this use in Canada • Supports new communication technologies and opportunities for interoperability between Canadian first responders such as police, fire, EMS • Also harmonized with United States to allow interoperability between public safety users in the Canada/US border area

  9. Broadband Public Safety at 4.9 GHz • Canada has new primary allocation to mobile service in the band 4940 - 4990 MHz and designated its use for fixed and mobile broadband applications in support of public safety • Support a wide variety of applications for public safety and provide sufficient flexibility to customize user’s operations • Applications may include: • local cellular coverage of cities using BB technology to distribute in a fixed or mobile mode: • automatic high speed file transfers (e.g. transfer of maps, building layouts, EMS files, missing person images etc) from emergency sites to mobile units • traditional fixed point-to-point and point-to-multipoint microwave operations, ancillary to public safety mobile operations to support backhaul or backbone communications links.
