11n requirements but incorporate only a single antenna. 11n making mandatory at least two antennas in an AP, but only one antenna in a non-AP device. 5 Merging of proposals After the failed confirmation vote, a joint proposal effort was started within the task group to merge the two competing proposals. Due to entrenched positions and the large membership of the group, the joint proposal effort proceeded very slowly. As a result, Intel and Broadcom formed the Enhanced Wireless Consortium (EWC) in October 2005 to produce a specification outside the IEEE that would bring products to market faster.
The comparison criteria in Stephens (2004) outlined metrics and required disclosure of results which would allow for comparison between proposals under the same simulation setup and assumptions. The comparison criteria incorporated the simulation scenarios and usage models defined in Stephens et al. (2004). During the development of the comparison criteria, the task group realized that members of the task group did not always share the same definitions for common terms. Therefore definitions for goodput, backward compatibility, and signal-to-noise ratio (SNR) were provided.

Introduction 15 and video content over the Internet or the redistribution of standard or high definition TV signals. 11g primarily through the use of spatial multiplexing using MIMO and 40 MHz operation. To take advantage of the much higher data rates provided by these techniques, MAC efficiency is also improved through the use of frame aggregation and enhancements to the block acknowledgment protocol. 11g. Robustness is improved inherently through the increased spatial diversity provided by the use of multiple antennas.
