  2. Abstract Discussion of concepts to be used to differentiate use case requirements. In the r0 form of this slide set the names of those characteristics had not yet been determined. Tom Siep, CSR

  3. xxx1 • Xxx1 is the number of STAs attempting to establish a link as measured over a one second time interval. • High: more than 100 • Medium: 10 to 99 • Low: 1 to 9 • Link Attempt Rate  • Rate of STA Entry Tom Siep, CSR

  4. xxx2 • Xxx2 is the “busyness” of the wireless medium of the ESS. It is measured as the percentage of time the medium is in use. • High: More than 75% • Medium: ESS is between 75 to 25% channel • Low: Less than 25% • Media usage Tom Siep, CSR

  5. xxx3 • xxx3 is the time the STA is within the ESS range. This time is the maximum available time for establishing a link and exchanging data. • High: • Medium: [discussion point] • Low: • STA dwell time • Time Envelope • Available time Tom Siep, CSR

  6. xxx4 • Xxx4 is the amount time required to establish a link. This includes the time for AP/Network discovery and (secure) Association and Authentication • High • Medium • Low • NOTE: • “link”, “association”, authentication are defined as per 802.11 • We need to agree when to start measuring this time interval (e.g. when the STA enters the coverage of the ESS, etc.) • Link Set-Up Latency • Link Set-Up Time Tom Siep, CSR

  7. xxx5 • Xxx5 is the time required by the use case for application information exchange. In order to make the use case work, Xxx5 must be smaller than xxx3 – xxx4 . • High: • Medium: • Low: • Application Time Tom Siep, CSR
