6. Scope of Proposed Project: `To develop a High Speed (about 20 Mbit/s) PHY for use in fixed, moving or portable Wireless Local Area Networks. The PHY will be used in conjunction with the 802.11 Medium Access Control (MAC). The 802.11 MAC will be reviewed to assure its capability to operate at the speeds targeted by the project.`

7. Purpose of Proposed Project: To create a high speed wireless access technology suitable for data, voice and image information services. This technology should be beneficial for improved access to fixed network LAN and internetwork infrastructure (including access to other wireless LANs) via a network of base stations, as well as creation of high performance ad hoc networks. The project will focus on communication techniques which use the spectrum efficiently and enable a high aggregate throughput, as well as high speed for an individual network.

Supplement to a High Speed Wireless LAN PHY PAR

6. Scope of the Project

To develop a High Speed (about 20 Mbit/s) PHY for use in fixed, moving or portable Wireless Local Area Networks. The PHY will be used in conjunction with the 802.11 Medium Access Control (MAC)

Radio Spectrum Availability

Currently 802.11 supports rates of 1 and 2 Mbit/s rates in the 2.4 GHz ISM band. Since the inception of 802.11 things have changed both in a regulatory arena and regarding the needs for higher transfer rates.

Specifically, in the US, FCC released 300 MHz in three 100 MHz subbands in the 5 GHz region (ET Docket 96-102) for an unlicensed use with high speed Local Area Network communication services. The structure of the new regulations encourages communication at speeds of about 20 Mbit/s. These rulemakings are evidenced by subpart E - Unlicensed National Information Infrastructure Devices in Part 15.4xx. In Europe, the CEPT has recommended the use of spectrum in the 5150-5250 MHz band for so called HIPERLAN devices in CEPT Recommendation T/R 22-06.

Given the regulatory changes (as opposed to 15.247 which was the basis for 802.11's work), it becomes feasible to develop efficient high speed modulation methods to address the 20 Mbit/s speed range. The scope of the proposed PAR is to propose such modem technology and methods as to take advantage of the new regulations. The modem technology will be examined with respect to propagation impairments typical of both indoor and reasonable range outdoor environments. The tradeoffs between spectral efficiency, immunity to interference and implementation complexity will be taken into account to address the need for high aggregate throughput in densely populated environments.

IEEE P802.11 has actively corresponded with regulatory bodies worldwide in the past in order to encourage spectrum allocations to allow its standards to be applicable geographically as widely as possible and plans to continue these activities.

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 intent of the effort of this PAR is to examine rates beyond the 20 Mbit/s range. The 802.11 MAC will be reviewed for its capability to support such rates. In addition, the MAC will be reviewed to examine its capability to support the data, voice and image services intended in the rulemaking.

The 802.11 MAC relies on a Clear Channel Assessment (CCA) mechanism in the Physical Layer for avoiding collisions with other transmissions. The CCA for the new Physical Layer will be developed to ensure fairness with respect to participating stations and ensure operation in presence of other types of radio devices operating in the environment, according to the spirit of the FCC rulemaking.

The proposed PHY with 802.11 MAC will meet Quality of Service as detailed in 802.11 PAR.
