Sdr adoption timelines

SDR Adoption Timelines

Infrastructure:

<2001Initial 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:

<2001Many 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:

<2001Fielded 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

Sdr handheld framework

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


Sdr software download issues

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


Regulatory activities

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


Sdr regulatory issues

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.

Sdrf download protocol

SDRF Download Protocol

  • Initiation: download request initiated by user terminal or source device/server

  • Mutual authentication: between download source device and user terminal

  • Capability exchange: to ensure terminal can accept, install, run downloaded code

  • Download acceptance exchange: source provides information on certification/type approval of code, download procedures/schedules, installation procedures, billing and licensing options, etc.

  • S/W download, integrity test: in-line integrity testing, retransmission requests

  • S/W installation: may be initiated by user terminal or source device

  • In-situ testing: test vectors downloaded with program code

  • Non-repudiation exchange: confirm successful installation and activation

  • Activation and billing

MExE Presentation: 29 March 2000, London, UK


Sdrf download api model

SDRF Download API Model

  • SDRF Download API forms the interface across which all programmable functionality of the terminal is defined.

  • Applies to both functional definition at time of manufacture, or in the field by an authorized user.

MExE Presentation: 29 March 2000, London, UK


Three tier sdr api model

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.

MExE Presentation: 29 March 2000, London, UK


Software download scenarios

Software Download Scenarios

Software download scenarios under development to determine SDR Forum framework:

  • Implications on API designs, including capability exchange features

  • Regulatory implications, including network integrity, security, billing, and licensing/type approval issues

  • Implications on new standards (e.g. 3G cellular) and modifications to existing standards to accommodate software download
