Agenda Data, Voice, and Video doc.: IEEE 802.11-02/474r0 July 2002 Agenda Data, Voice, and Video Diagnostics (non-802.11, 802.11, other APs) Station Table (BSS and IBSS) Link Statistics (counts, data rates, RSSI, link margin) MAC Statistics (channel utilization, total stations, events) Events (auth, deauth, associate, deassociate, current MIB) Coexistence Measurements Richard Paine, Boeing Richard Paine, Boeing

Data, Voice, and Video Data Voice Video Signal Strength BER Delay July 2002 Data, Voice, and Video Data Signal Strength BER Voice Delay Jitter Rx Quality Real-time parameters Retries Transmission Speed Video FEC Richard Paine, Boeing

MIB Information What info to be added to MIB? July 2002 MIB Information 802.11 MIB Basic measurements & configuration for STA Widely implemented in APs Very simple monitoring of global AP statistics 802.1x MIB Detailed auth state for individual 1x ports Also some per port statistics Not widely implemented in access points today Bridge MIB Possible to get some info on which STAs are associated with an AP Implemented in some APs Not 802.11 specific, little MAC, and no PHY statistics What info to be added to MIB? 1X info in .11 STA table? AP info in .11 STA table? Richard Paine, Boeing

Diagnostics Rogue access points and what to do about them? July 2002 Diagnostics Rogue access points and what to do about them? Interference from non 802.11 sources Microwaves HomeRF Bluetooth Cordless Telephones Interference from other 802.11 networks FH DS Interference from other APs within same ESS Test APs in the same building as production What are other sources of 2.4 And 5.15GHz energy? What information is needed to distinguish impacts of FH & DS? Boeing has lots of test networks running in the same areas as production. Richard Paine, Boeing

Station Table Station table is list of wireless STAs an AP knows about July 2002 Station Table Station table is list of wireless STAs an AP knows about Vendor Signal Strength Jitter Delay MAC Address Stations communicated with Also applicable to IBSS Currently implemented by many APs, as proprietary MIB/telnet/web interface Authenticating stations Authenticated stations Associated stations What does the AP need To know about the STAs? Richard Paine, Boeing

July 2002 Card Table Card table is list of wireless STAs and APs a card knows about: Vendor Signal Strength Jitter Delay MAC Address Stations communicated with Also applicable to IBSS Currently implemented by many card vendors, as proprietary MIB/telnet/web interface What does the STA need to know about the STAs and the APs? Richard Paine, Boeing

Link Statistics dot11MACStatistics Counts of July 2002 Link Statistics dot11MACStatistics Counts of MSDUs/MPDUs received/transmitted Channel utilization in rx & tx direction Measured as total μs Data rate & modulation of last rx and tx RSSI, signal quality Link margin as seen by other station Available for 11h stations Either use recent measurement report, or request report for each SNMP request What statistical and specific Information is needed about The quality of the link over time? What can we do without changing the PHY? Richard Paine, Boeing

MAC Statistics Channel utilization from TGe Total associated stations July 2002 MAC Statistics Channel utilization from TGe Total associated stations Total authenticated stations Optional events to notify mgmt station of authentication and association events Current MIB sends TRAPS on assoc/auth failures What can we do without changing the MAC? Richard Paine, Boeing

Events Allow all events to be configurable as July 2002 Events Allow all events to be configurable as Not reported Reported as TRAP (unreliable) Reported as INFORM (reliable) Default configuration should give same events as current 802.11 MIB Report all pre RSN auth/deauth events Report all association/deassocation events What could we do with event information about STAs/APs being added or subtracted? Richard Paine, Boeing

Methods of Coexistence July 2002 Methods of Coexistence What is channel availability? Adaptive Frequencies Spatial Diversity Unused Frequencies Coding Timing What frequencies are open in a dual mode card? What would a software radio need to know to switch logical radios? Richard Paine, Boeing

Coex Hierarchy of Needs July 2002 Coex Hierarchy of Needs What information is needed To negotiate coexistence? 5. Negotiate coexistence 4. Optimize your own environment 3. Be passively aware (FH WLAN or BT) 2. Aware but expects others to adjust (DS WLAN) 1. Unaware (microwaves) Richard Paine, Boeing

Conclusions Lots of issues to write submissions about doc.: IEEE 802.11-02/474r0 July 2002 Conclusions Lots of issues to write submissions about Lots of requirements to write submissions about Monterey – submit the PAR and 5 Criteria Monterey – have submissions on requirements and issues Monterey – Submissions on vision Monterey – select draft pictoral vision of end goal Kauai – submissions on solutions (MIB, MAC, PHY, spec) Ft Lauderdale – Submissions on solutions and draft outline Richard Paine, Boeing Richard Paine, Boeing
