Scope of the Project

The scope of this project is to develop a higher speed PHY extension to 802.11 operating in the 2.4 GHz band.

The project will evaluate the possibility of taking advantage of the provisions for rate expansion that are in place on the current standard PHYs.

The 802.11 MAC defines a mechanism for operation of stations supporting different data rates in the same area. The current 802.11 standard already defines the basic rates of - 1 Mbit/s and 2 Mbit/s for both Frequency Hopping (FH) and Direct Sequence (DS) PHYs. The two rates are supported by having same header for both rates with length and rate information passed in the header at the lowest ("basic") rate; then the body of the packet is transmitted at the rate chosen and with the corresponding modulation method.

The header structure of the two PHYs already supports passing rate information up to 4.5 Mbit/s (in 0.5 Mbit/s increments) for FH and up to 25.5 Mbit/s (in 0.1 Mbit/s increments) for DS. The proposed PAR targets further developing the provisions for enhanced data rate capability of 802.11 networks.

The 802.11 MAC incorporates already the interpretation of this information and the computation of expected packet duration even if the specific station does not support the rate at which the packet was sent.

The 802.11 MAC is compatible and will accommodate the higher PHY rates.

Compatibility with 802.11 MAC

The 802.11 PAR mentions that the MAC will be capable of operation in the 1-20 Mbit/s range. The 802.11 MAC will be reviewed for its capability to support rates up to about 10 Mbit/s targeted by the extended modulation methods.

Data rate

The data rates targeted by this project are at least 3 Mbit/s for FH PHY and at least 8 Mbit/s for DS PHY.

Radio Spectrum Availability

The proposed extensions will operate in the already allocated 2.4 GHz ISM band, in which 802.11 is already defined.

IEEE P802.11 will correspond with regulatory bodies worldwide in order to try to assure that the proposed extension will be applicable geographically as widely as possible.


The purpose of project 802.11a is also for higher data rates, however, that project is for operation in the 5 GHz band, whereas this project is for operation in the 2.4 GHz band


The Working Group will adhere to the IEEE patent policy.
