23 Adding Brilliance to Information Appliances Using the Wireless Internet 802.11b Wireless Interactive Access to: Job Status Application Codes File Storage

24 Goal: Smooth Handoff by Mobile Device Faced With Heterogeneous Access Network WLAN GPRS CDMA CDPD Internet (802.11b) (CDMA20001xEV) Our Focus: Identify Issues Related to Handoff Between WLAN and WWAN Networks and Implement a Test-bed Ramesh Rao, Kameshwari Chebrolou UCSD-CWC, Cal-(IT) 2 Discussing Field Tests of Birdstep Technology & Ericsson

25 The Implementation is Based on Co-Allocated Mobile IP The Mobile Terminal Obtains a Care-of-Address (CoA) From the WLAN/WAN Network The Mobile Terminal (MT) Informs the Home Agent of the CoA The Home Agent Routes Packets From the Remote Host to This CoA by Tunneling (Encapsulation) The MT Does the Decapsulation The MT Sends Packets Directly to the Remote Host Ramesh Rao, Kameshwari Chebrolou UCSD-CWC, Cal-(IT) 2

31 University Free Nets are Leading to Community Open Access Networks Free Access to Local Information Gateway to Choice of Internet ISPs Ericsson is Co-Sponsor KTH and the City of Stockholm cooperating –Beginning to Deploy Bay Stations in City Discussions on Creating SwedenOpen

32 Rapidly Growing 802.11b Community Wireless Network in Seattle We are using widely-available, license-free technology to create a free, locally-owned wireless backbone. This is a MetropolitanAreaNetwork (not just a "wireless LAN" in your home or business) and a community- owned, distributed system (not yet another service provider to whom you owe a monthly bill).

33 The 802.11b WLAN Node Movement Has Hit Sweden! If you have a broadband or DSL connection in your home or office, buy an access point, hook it up, and you are a node operator. The project grew out of a skepticism towards the claims of the telecom industry regarding the usefulness and success of the future "third generation mobile telephone systems" as the only means to implement "the wireless Internet". We envision a cloud of free Internet connectivity that will cover most inhabited areas. The coverage might be spotty, vary over time, and be hard to control or predict, just like a fog or smog. 369 members as of June 1, 2001

34 Will The Planned Global Rollout of 3G Proceed as Planned? Lack of 3G Global Standardization –Constrains Economies of Scale The Economics of Telecom –The Huge Debt Load –The Investment in 3G Buildout –Is There a Business Case to Recoup? Technological Breakouts –IEEE 802.11 Buildout –3G (Data-Only) Can Deploy Now (CDMA20001xEV) –Will They Skim the Cream of the 3G Market?
