4. MIB Information What info to be added to MIB?
July 2002
MIB Information
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 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

5. 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 sources
Microwaves
HomeRF
Bluetooth
Cordless Telephones
Interference from other 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.

6. 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

7. 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

8. 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

9. 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

10. 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 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

11. 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

12. 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)
