802.16 Future Areas

IEEE 802.16eWill 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.

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

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.

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)

Source: IEEE P 802.20™ V14

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.
