  1. Wi-Fi Alliance Issues inWLAN Roaming Serge ManningIETF 58 - RADEXT BOF

  2. What is Wi-Fi Alliance? • Wi-Fi certification • WLAN equipment (access points, PC cards) • Focus on Public Access • Commercial WLAN systems in the public space • Market Requirements Document (MRD) • To lead to Public Access certification of Wi-Fi products. • Status • MRD in progress. • Estimated Completion: Dec 2003 – March 2004.

  3. Wi-Fi Alliance Market Reqs Document • Background • Support for WLAN security: Wi-Fi Protected Access (WPA) • WEP vs WPA vs 802.11i • WPA does not require hardware changes • Universal Access Method • “Browser Hijack” • User enters username and password • MRD Addresses • Coexistence • Very important to support UAM and WPA simultaneously • MRD recommends set of standard attributes for UAM and WPA. • Network Discovery • Requirements may impact attributes • Prepaid Support • Using existing attributes • Set of Use Cases Certification • WFA will certify support of attributes in the access point

  4. Use of Vendor Specific Attributes • MRD currently uses WISPr VSAs • Available in http://www.weca.net/OpenSection/downloads/WISPr_V1.0.pdf • Hot Spot Location • Geographic area, location name • Operator Identification • Name and type of WLAN operator • User Bandwidth • Minimum and maximum uplink/downlink bandwidths • Would like to migrate to standard attributes • Developed in RADEXT

  5. Wrap Up • Role of WFA • Determining market requirements (define the problem) • Pull together a solution across multiple operator types (not GSM, CDMA, or WISP specific) • Generate test plans and certify equipment (enforcement) • Role of IETF – RADEXT • Develop specifications that recommend one way to solve a problem • Eliminate confusion when different solutions exist. • Attributes • WFA would like to point to IETF documents for lists of WLAN roaming attributes.
