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

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

How will the standard operate? Flarion plans to support 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)

Source: IEEE P ™ V 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.

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

Who is Using 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

Who will be Using 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)

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)

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)

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
