Annex: Scope of original project:

To develop a Medium Access Control (MAC) and Physical Layer (PHY) specification for wireless connectivity for fixed, portable and moving stations within a local area.

Type of medium

The goal is that the MAC shall support PHYs using electromagnetic waves through the air (i.e. radio waves as well as infra-red or visible light).

PHY layer suitable for use with the electromagnetic frequency spectrum as described in the following paragraph will be defined with this standard. If evidence of need and sufficient interest exists other PHY layers will be considered at a later time.

Radio spectrum

Currently the only available unlicensed spectrum is in the ISM bands in the USA provisionally 915 MHz band in Canada and Australia. Test programs are underway in the UK and elsewhere, evaluating license free operation.

The initial effort will be for the ISM bands and to consider the use of additional bands beyond ISM.

However, these ISM bands are already heavily used, and it is felt that service degradation from other users will happen, increasing with time. Therefore, in order to further development of the standard, the 802.11 committee should participate in the development of changed or new regulations for short distance radio services in which all authorized users of any new frequency allocation shall be permitted to radiate only a defined maximum power density. The goal is to provide regulations which allow for an easy approval process for the end-user.

To further enhance the standard the 802.11 committee will undertake to document the benefits of, and make recommendations for international spectrum allocation and use, where possible.

Supported Stations

The standard shall support stationary stations, movable stations, and mobile stations moving at pedestrian and vehicular (local premises environment) speeds. This is to be implemented with one PHY if feasible.


Because the range of wireless transmission / reception may be smaller than the physical coverage area desired, a distribution system designed to provide range extensibility will be addressed as part of this standard.

The standard will include support of the following:

- Basic Service Area (BSA) in which each station can communicate with any other station in the BSA.

- Extended Service Area (ESA) in which each station can communicate with any other station via the defined and managed Distribution System.

- Stations which interoperate in both BSA and ESA shall be defined if feasible.

Possible target environments include:

* in buildings and other premises such as offices, financial institutions, shops, malls, small and large industry, hospitals and residences,

* outdoor areas such as parking lots, campuses, building complexes and outdoor plants and storages.

Note: The definition of performance classes within a PHY may be necessary to support environments with benign or hostile characteristics.
