  3. U.S. FCC Update • FCC SDR Definition: “A radio that includes a transmitter in which the operating parameters of frequency range, modulation type or maximum output power (either radiated or conducted), or the circumstances under which the transmitter operates in accordance with FCC rules, can be altered by making a change in software without making any changes to hardware components that affect the radio frequency emissions.” (47 CFR. Sec. 2.1) • Particularly suitable for shared use bandwidth • Updated FCC Cognitive Radio Report and Order (March 2005) • FCC continues to be favorable to cognitive radio and to evolve its rules GSC: Standardization Advancing Global Communications

  4. History to Date • 2001 – FCC adopted changes to the equipment authorization rules to accommodate SDR • 05/2003 – FCC workshop • 12/2003 – FCC adopted Notice of Proposed Rulemaking and Order to explore uses of cognitive radio technology to facilitate improved spectrum access • 11/2004 – FCC approved first SDR: Vanu, Inc. wireless GSM base station • 03/2005 – FCC adopts rule changes for smart radios. • 05/2005-07/2005 – Several petitions for reconsideration/clarification filed GSC: Standardization Advancing Global Communications

  5. ITU-R Activities • Approved: • ITU-R Working Party 8F: Draft New ITU-R Report M.[IMT.SDR]: “The impact of Software Defined Radio [IMT.SDR] on IMT-2000, the future development of IMT-2000, and systems beyond IMT-2000” • ITU-R Working Party 8A: Draft New ITU-R Report M.[LMS.SDR]: “Software Defined Radios in the Land Mobile Service” • New Work: • Tasked WP8A to produce a consolidated SDR report based on above and with further input from Working Parties 8B (radars), 8D (mobile satellite systems) and 8F (IMT-2000 and systems beyond IMT-2000). • Above reports will be withdrawn upon the adoption of the consolidated report. • WP8A has begun process of developing new report and liaisons with the other working parties.

  6. Desired SDR Terminology • For in-vehicle use, to address the mismatch between the lifecycles of vehicles and communications technology: • Software Reconfigurable Radio: A software defined radio that (1) incorporates software-controlled antenna filters to dynamically select receivable frequencies, and (2) is capable of downloading and installing updated software for controlling operational characteristics and antenna filters without manual intervention. GSC: Standardization Advancing Global Communications

  7. Key SDR Applications • Land mobile systems, including IMT-2000 • Wireless Access Systems (WAS), including Radio Local Area Networks (RLANs) • Public Protection and Disaster Relief (PPDR) • Intelligent Transport Systems (ITS) GSC: Standardization Advancing Global Communications

  8. Software-Reconfigurable Radios and ITS • In-vehicle safety requires in-vehicle data communications units (DCUs) that can remain connected for the vehicle’s entire service life • Software reconfigurable radios can improve DCU logistics and affordability • Facilitates low-cost software reconfigurability • Minimizes the need to physically replace hardware • DCU software must be • Updatable • Remotely downloadable • Able to support multiple data communications capabilities • Adaptable to new protocols and frequencies GSC: Standardization Advancing Global Communications

  9. SDR Challenges (1) • The timing of market opportunities/practicality is still uncertain • Standards development needs to be accelerated, particularly for vehicle use • Regulatory issues abound • Will continue to be an issue as widespread commercial deployment and use evolves • Devices must be licensed for multiple radio spectra • There are international regulation and political implications • Existing radios in vehicles must be licensed for new spectra and protocols GSC: Standardization Advancing Global Communications

  10. SDR Challenges (2) • Technical issues remain • Smart antennas, security for software download, etc. • Compatibility between devices and network infrastructures • Scalability • Security • Dynamic radio configuration – interoperability in multiple networks needed simultaneously • High data rates for next generation platforms • Must meet the social need for vehicle safety radios that work 25 years after design starts GSC: Standardization Advancing Global Communications
