  1. OUTLOOK 802.20 Broadband On the Run

  2. Overview • Wireless Infrastructure • Broadband mobile wireless access protocols • 802.16 • 802.20 • 802.16 Vs 802.20 • Technology stand in market • Products and their costs. • Conclusions

  3. Wireless Infrastructure • Wireless communication no longer means mobile Plain Old Telephone Service • Integration of media and services • IP based control protocols are much better than the combination of circuit and packet technologies in use today. • SIP (Session Initiation Protocol)- IP based multimedia services • Broadband technology is needed to provide foundation for future Wireless multi-media networks

  4. The Wireless Space Source: ICBN 2004 Kobe Japan

  5. Mobile Broadband Wireless Access (MBWA) • Unmatchable capability of wireless medium-mobility • MBWA • An efficient packet based air interface that is optimized for the transport of IP based services. • Goal: Provide affordable, ubiquitous, always-on and interoperable multi-vendor mobile broadband wireless access networks • The MBWA Study Group • 802.16 • 802.20

  6. 802.16: Fixed Broadband Wireless Access: Wi-Max • WAN technology that can beam broadband signals up to 30 miles from a cell tower. • Frequencies from 10 to 66 GHz • Future • Basis for ubiquitous, continue mobile wireless connectivity-802.16e. • Bandwidth • 75 Mbps of bandwidth for 2 to 3 miles.

  8. 802.16 Future Areas • IEEE 802.16e • Will allow seamless handoffs between base stations. • Providing true mobile broadband connectivity. • Development needed to 802.16 protocol. • Aims basically at throughput than mobility. • 802.20 is developed to cover the mobility part of the 802.16.

  9. 802.20 Mobile Broadband Wireless Access: Mobile-Fi • Broadband on the Run (up to 250 km/hr, 155mph) • Standard Air Interface for Mobile Broadband Wireless Access Systems Supporting Vehicular Mobility - Physical and Media Access Control Layer • Still being developed • Led by companies such as Flarion Technologies and ArrayComm

  10. 802.20 • The IEEE 802.20 standard should form the basis for systems that support seamless integration of the three user domains - work, home, and mobile, with various scenarios. • The 802.20-based air-interface (AI) shall be optimized for high-speed IP-based wireless data services. Source: IEEE P 802.20™ V14

  11. 802.20 • How will the standard operate? • Flarion plans to support 802.20 MBWA using Orthogonal Frequency Division Multiplexing (OFDM). This multiplexing technology divides a single high-speed channel into multiple parallel low-speed channels that do not overlap.(1) • Motorola Proves 300Mbps possible using OFDM(2)

  12. 802.20 • Will operate in licensed bands between 500 MHz and 3.5 GHz. • Ranges of up to 15 kilometers (km) are likely at peak data rates of 1 Mbit/s per user. • PC card interface with devices must be used. Source: IEEE P 802.20™ V14

  18. 802.20 Products on the Market • Nextel selects Raleigh/Durham/Chapel Hill, NC region for 802.20 trail, participants will get the technology free, if selected. (3) • T-Mobile is conducting wireless broadband trials in Holland using 802.20 equipment. (4) • Flarion is working with the District of Columbia to deliver a showcase network for public safety and first responders, completed Sept 2004. (5), (9)

  19. Who is Using 802.20 Now • Motorola and Flarion installs first of its kind wireless broadband data network for police and fire in Washington DC(5) • No full scale deployment to consumers at this time

  20. Who will be Using 802.20 • Every industry tends to gain from mobile broadband, but an immediate need exists in industries that employ large sales forces such as insurance, pharmaceuticals/health care and real estate. (5) • Wireless broadband benefits will not be realized unless a LAN-like experience in the wide area environment is offered. (5)

  21. 802.20 Market Analysis • By 2006, 46% of American Households will have broadband connections. • The dramatic uptake of cable and DSL shows that for wireless data to succeed, the same attributes must be offered: • Broadband speeds (1-1.5 Mbps typical user experience) • Low latency (less than 50 ms) • Similar pricing (6)

  22. 802.20 Market Analysis • Companies will be able to reduce some of the overhead and operational costs associated with large, centralized headquarters and call centers, as well as costs associated with travel and remote access to the Internet and corporate LAN.(5) • The 9-11 Commission recommends a national wireless high speed public safety network. (7)

  23. 802.20 Market Analysis Applications intended for low latency, QoS and broadband speed • Internet Gaming: smooth, predictable controls, timely feedback • Internet messaging: keeps flow of conversation in-sync • VoIP: natural pace of conversation, no strained waiting • Video Conferencing: less dropped frames = less jitter

  24. 802.20 Market Analysis Main selling point of 802.20 mobility problem: The majority of Americans prefer to drive their own car. How will they benefit from mobile internet connection? Source: Bureau of Transportation Statistics – www.bts.gov

  25. Competing Technologies & Products • 802.16, A standard for fixed wireless connectivity being considered for use in a mobile environment • 3G / 4G • The future of Wireless Broadband is still up in the air (8)

  26. Devices that 802.20 will affect • Cell Phones • PDA's • Laptops • WLAN's

  27. Hype Cycle for New Technologies • Hype Cycle Stages • Technology Trigger • Peak of Inflated Expectations • Trough of Disillusionment • Slope of Enlightenment • Plateau of Productivity Source: Gartner Research

  28. Is 802.20 All Hype?

  29. Conclusion • Provides the user an “Always-On” experience • 802.20 also supports broadcast/multicast • Not yet launched into the market • If there's success in the 802.16 market, it will definitely mean good things for the 802.20 market • 802.20 maybe a direct competitor to third-generation (3G) wireless cellular technologies.
