Scope of IEEE 802.20

Develop a specification for the PHY and MAC layers of an air interface for interoperable packet-data mobile broadband wireless access systems that:

- operates in licensed frequency bands below 3.5 GHz,
- supports peak data rates per user in excess of 1 Mbps,
- supports vehicular mobility classes up to 250 Km/h,
- covers cell sizes commensurate with ubiquitous metropolitan area networks, and
- targets spectral efficiencies, sustained user data rates and
numbers of active users significantly higher than achieved by
existing mobile systems.

IEEE 802.20 (MBWA) Purpose

Enable worldwide deployment of cost effective, spectrum efficient, always on and interoperable mobile broadband wireless access systems in order to address user needs for:

- Mobile and ubiquitous Internet access
- Transparent support of Internet applications
- Access to enterprise intranet services
- Transparent access to Infotainment and Location services

This specification fills the performance gap between the high data-rate low mobility services currently developed in 802 and the high mobility cellular networks

Broad Market Potential

a) Broad sets of applicability.
b) Multiple vendors and numerous users.
c) Balanced costs

The capability of the wireless medium to support mobility is a feature unmatched by the capabilities of wireline broadband access networks. The mobile capability has proven vastly successful as can be seen from the abundance of narrow-band mobile devices. Mobile broadband wireless access, based on IP mobility, unlocks all Internet content to the general public, potential addressable market is all users of IP - based services and applications. These include:

- Secure Enterprise Intranets and VLAN Services

- Entertainment & Gaming

- Internet and Location Services

Mobile station and terminal equipment are provided by multiple international telecommunications equipment vendors, deployed by international carriers and made available to the end-user community.

This project will achieve cost balance between terminal devices and network infrastructure equipment that is comparable to existing cellular wireless networks and encourage mass deployment of wireless data services. Given that base stations can serve many mobile terminals, the cost of the network equipment can easily be spread over many users. Terminal devices and associated chip-sets are expected to benefit from volume deployment, large-scale integration and an optimized IP-centric design to achieve low cost.
