Proposed Evaluation Methodology Addition

1. Proposed Evaluation Methodology Addition Date: 2010-01-21 Shu Kato, NICT

2. Abstract • This document proposes an additional clause to the Evaluation Methodology document for better co-existence of proposals and the existing systems in the same band Shu Kato, NICT

3. Proposed Addition • Proposers shall describe mechanisms by which coexistence of an 802.11adAP and other 60 GHz systems and standards in the band • Add clause to section 2 or 4 for FR Req08: • Proposers shall describe mechanisms by which coexistence of an 802.11adAP and other 60 GHz systems and standards in the band is covered by the proposal. This should include coexistence with IEEE 802.15.3c. Thosemechanisms may include energy detection, preamble detection or the use of some universal mode to communicate between the 802.11ad AP and the devices of the other 60GHz systems and standards.  Once an interferer is detected, the 802.11ad AP should avoid interference through the use of beamforming, use of alternate available channel or other means to coexist. If the 802.11ad AP and the devices of the other 60GHz systems and standards operate co-channel, the performance of the coexistence mechanism can be measured by the effective throughput of the device in the presence of the interferer operating within the band.

4. Conclusion • This document has proposed an additional clause to Evaluation Methodology document for better coexistence • The proposed clause reflects the comments received on the doc. IEEE802.11/1160r3 • The proposed clause will not force any burden but ask the necessary mechanisms of co-existence Shu Kato, NICT
