  6. What is SDR? • An efficient solution for introducing wireless devices and services that can be enhanced using software upgrades. • A key to providing consumers with a wide variety of services built around wireless Internet access. MExE Presentation: 29 March 2000, London, UK

  7. SDR Benefits • Reduce time to market. • Reduce the number of product platforms to develop and support. • Introduce product and service architectures that can be systematically scaled to higher data rates and user densities. • Enable over-the-air product upgrades, service upgrades, and bug fixes. • Differentiate and customize value-added products and services. • Offer access to advanced digital services and seamless roaming on any wireless technology. MExE Presentation: 29 March 2000, London, UK

  8. SDR Adoption Timelines Infrastructure: <2001 Initial limited use by commercial cellular infrastructure manufacturers and military/ aerospace equipment manufacturers 2001… Increased commercial, civil, and military use, driven by the development and initial deployment of third generation commercial wireless systems and the need for multi- service capabilities in civil and military markets 2005… Widespread adoption by most manufacturers as core platform User Terminals: <2001 Many R&D efforts worldwide, little commercial usage 2001… Initial usage to meet growing demand for multimode, multiband product platforms for 1G and 2G commercial wireless market, as well as civil and military markets 2003… Increased usage to add 3G commercial wireless capabilities 2005… Widespread adoption and movement to SDR as baseline design Other Products: <2001 Fielded applications in various radio/ wireless products 2001… Increased usage in wireless and non-wireless products as SDR technology matures 2005… Potential for widespread utilization in products receiving/transmitting in 100MHz range MExE Presentation: 29 March 2000, London, UK

  13. SDO=Standards Development Organization Member Inputs Does SDO exist for Concern and Need? Identify Technical Concerns and Standards Needs Identify User Needs N SDRF seeks SDO to accept owner- ship Y Y Industry Inputs SDRF Delivers “Standards Recommendation” Document N SDO Considers Input in Standards Activities SDRF Develops “Standards Recommendation” SDO Develops and Releases Standards to Industry SDRF Releases “Standards Recommendation” to Industry SDR Forum Standards Process MExE Presentation: 29 March 2000, London, UK

  14. SDR Forum Domains SDR Forum work to date has recognized 3 major domains: • Base Station • Fixed, multichannel, high power • Mobile • Vehicular, dynamic networking • Handheld • Small, light weight, very portable, battery operated, radiation constraints MExE Presentation: 29 March 2000, London, UK

  15. I I I I I Optional Link Processor H/W MSG Process & I/O Antenna INFOSEC RF Baseband C C C C C Routing C C C C C C SDR Mobile Architecture • Modular hardware and software • Open H/W and S/W interfaces defined by SDRF APIs • Hardware reconfigurability and software programmability Voice Data Multimedia Flow Control Network Control Source: SDR Forum Technical Report 2.1, November 1999 MExE Presentation: 29 March 2000, London, UK

  16. SDR Handheld Framework • H/W and S/W implementations defined by manufacturers • Hardware reconfigurability and software programmability • SDR Forum focus on download protocol, messaging and capability exchange, and security/ regulatory aspects MExE Presentation: 29 March 2000, London, UK

  17. SDR Software Download Issues • Regulatory • Type approval • HW/SW compatibility • Authentication • Integrity of downloaded code • Network Interoperability • Security/ Fraud/ Encryption SDR software download encompasses all of the issues encountered by MExE in defining mobile client/server systems, e.g. for e-commerce MExE Presentation: 29 March 2000, London, UK

  18. Regulatory Activities • SDR Forum prepared White Paper on SDR commercialization roadmap for FCC, SDR Forum delegation presented recommendations to FCC Commissioners and Chairman in Washington DC,11/99. • FCC Notice of Inquiry (NOI) on SDR released 3/17/2000, accompanied by joint FCC/ SDR Forum press conference. • “Through this inquiry, we seek input to help evaluate the current state of SDR technology, and to determine what changes to the Commission’s rules are necessary to facilitate deployment of this technology”. • In addition to FCC, active participation in SDR Forum from European, and Asian regulators. • FCC will also support SDR Forum in definition and implementation of commercial SDR experimental testbeds. MExE Presentation: 29 March 2000, London, UK

  19. SDR Regulatory Issues • SDR requires equipment authorization agencies to certify combinations of hardware and software for compliance with relevant rules. • Such authorization can be carried out using same approach as used in today’s hardware testing, so long as software can be “sealed” to prevent tampering during the download process. • Approved hardware would then check “seal” to verify its authenticity before installing the software and allowing it to reconfigure any of the hardware elements in the user’s device. • Electronic encryption techniques already being assessed (i.e. by MExE) for mobile e-commerce transactions and other secure mobile services are expected to be robust enough to provide the necessary security.

  27. Three-Tier SDR API Model SDR Forum Technical Report defines the following 3-tier API model: • Tier 1: Functional (messaging) – key to SDR framework Describes messages, associated parameters, and expected responses required to initiate and effect S/W download from source to user • Tier 2: Transport Describes protocol used for download of code, including scheduling, error detection/ correction, fail/ retry mechanism, etc. • Tier 3: Physical Defines physical interface between download source/ server and user terminal Ongoing development of detailed message syntax, data structures, passed parameters, status information, capability/ configuration table structure and content.
