IEEE-SA Standards Board Bylaws on Patents in Standards
6. Patents
IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either
a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or
b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination
This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period.

Proposed Title (02-798r7)
Draft Amendment to STANDARD [FOR] Information Technology-Telecommunications and information exchange between systems-Local and Metropolitan networks-Specific requirements-Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Enhancements for Higher Throughput
Jon Rosdahl, BJ Consulting

27. July 2003
Proposed Scope (02-798r7)
The scope of this project is to define an amendment that shall define standardized modifications to both the physical layers (PHY) and the Medium Access Control Layer (MAC) so that modes of operation can be enabled that are capable of much higher throughputs, with a maximum throughput of at least 100Mbps, as measured at the MAC data service access point (SAP).
Jon Rosdahl, BJ Consulting

28. July 2003
Proposed Purpose (02-798r7)
The purpose of the project is to improve the wireless local area network (LAN) user experience by providing significantly higher throughput for current applications and to enable new applications and market segments.

18.Additional Explanatory Notes: (02-798r7)
Item 12.
The scope of the MAC and PHY enhancements assume a baseline specification defined by and its amendments and anticipated amendments a, b, d, e, g, h, i and j. The enhancements shall be to support higher throughput. The amendment shall not redefine mechanisms in the baseline that do not pertain to higher throughput.
Some of the modes of operation defined in the HT amendment shall be backwards compatible and interoperable with a and/or g.
Existing standards are typically designated by their peak physical data rates. For example, a has a peak data rate of 54Mbps. This amendment has chosen to use a performance metric of throughput measured at the MAC data SAP. This amendment seeks to improve the peak throughput to at least 100Mbps, measured at the MAC data SAP. Depending on the scenario, this represents an improvement of at least 4 times the throughput obtainable using existing systems.

18.Additional Explanatory Notes: (02-798r7) (cont)
In order to make efficient use of scarce spectral resources in unlicensed bands, the highest throughput mode defined by the HT amendment shall achieve a spectral efficiency of at least 3 bits per second per Hertz for the PSDU.
In the process of formulating this PAR, it was found that there are multiple user scenarios. Accordingly, the task group will undertake the following steps:   1. Identify and define usage models, channel models and related MAC and application assumptions. Initial usage models envisioned include hot-spot, enterprise and residential; others may be included.

2. Identify and define evaluation metrics that characterize the important aspects of a particular usage model. The evaluation metrics may include but are not limited to the items listed in Table 1, provided as an illustration of the format.
3. Develop a technical requirement specification.
4. Define a process for evaluations.
The impact of an HT device on the operation of a legacy network shall be comparable to that of any other legacy device identified in the baseline defined above.
