  1. Boeing Wireless & Mobility For UW Class on Wireless “Supporting static systems is the degenerate case of mobility and multihoming!!!.” Robert Moskowitz

  2. Agenda • Wireless and Mobility Status • Simple Requirement • Wireless Work Items for 2003 • Next Generation Wireless LANs • Location Enabled Network Services (LENS) • DHCP++ • Measurements for 802.11 and then 802 • Cellular Data to 802.11 Seamless Mobility • WLAN Context Transfer • Wireless Security • Mesh Networks • Layer 2 Routing and Context Transfer Protocols (CTPs) • Host Identity Payload • Big Picture

  3. Wireless and Mobility Status • 1200 Access Points • 60 Foot Cell 802.11b Deployments • Aiming for 802.11a Deployments

  4. Simple Requirement VOIP Over the Wireless LAN!!!!!!!

  5. Next Generation Wireless LANs • Next Generation Wireless LANs • Switch in the closet • Seamless 802.11 Management and Roaming • IEEE 802.11a • Generations 2 and 3 of 802.11a • Technology changes needed for these generations

  6. R Boeing Campus Boeing Wireless Mobility Model Level 4 - National/Intl Low Speed (19.2Kbps) Level 3 - Regional Low Speed Wireless (56Kbps) Level 1 - Personal Area Network (.5-10Mbps) Level 2 - Campus High Speed Wireless LANs (1-100Mbps)

  7. Location Enabled Network Services • Location Enabled Network Services • Vision and Architecture for LENS • Integration of LENS into Network Infrastructure • Triangulation Technologies • Signal Strength Technologies
