Summary of Proposed Text for Radio Measurement Requests and Reports January 2003 Summary of Proposed Text for Radio Measurement Requests and Reports Daryl Kaiser (Cisco Systems) 12 March 2003 Daryl Kaiser, Cisco Systems Daryl Kaiser, Cisco Systems

Proposed text specifies changes to 2003 draft January 2003 Proposed text specifies changes to 2003 draft Duplicates portions of TGh and TGe where needed Management frames with Action subtype Measurement Request and Report information elements Introduces new Action category: Radio Measurement Defines five radio measurements, allows more to be added Beacon, Frame and Hidden Node are completely new CCA, RPI Histogram format identical to Spectrum Mgmt category However, RPI Histogram measures only non-802.11 energy Daryl Kaiser, Cisco Systems Daryl Kaiser, Cisco Systems

Defines a different type of measurement: non-synchronized January 2003 Defines a different type of measurement: non-synchronized Spectrum Management (TGh) uses time-synchronized measurements Requests stations to start measuring at a specific time Requires AP to suspend downlink traffic to off-channel stations Radio Measurement (TGk) defines non-synchronized measurements Facilitates broadcast measurements without traffic storms Stations randomize the first requested start time by at least 4 ms Does not require AP to suspend downlink traffic Stations issue power-save notification when measuring off-channel Daryl Kaiser, Cisco Systems Daryl Kaiser, Cisco Systems
