  1. STS Enhancements Presenter: Tom Phillips

  2. Overview • Initial concepts • Market requirements • International standardization • Enhanced functionality • The way forward

  3. Historical roadmap • Working group constituted (August 2002) • User requirements collated (Feb 2003) • Concepts formulated (Oct 2003) • STS Standardization commenced (2004) • STS Enhancement reformatting (Nov 2005)

  4. User requirements • Backward compatibility • Existing one-way token transfers • Unit credit transfer • Meter specific management tokens • Numeric & Magnetic card token technologies

  5. User requirements • Bulk data transfers • Meter configuration tables • Tariff tables • Feedback information • Consumption feedback data

  6. User requirements • Meter feedback data • Meter capability • Default consumption feedback • Specific detailed information • Meter status • Customer profile information

  7. User requirements • Dual key management • Facilitates zoning • Simplifies field maintenance • Assists management

  8. User requirements • Token carriers • Numeric • Magnetic card • Dallas iButtons • Smartcards • Wireless / PLC carrier technologies
