Optimizing RFID Tracking on Access Points

To optimize the monitoring and location calculation of RFID tags, you can enable tracking optimization on up to four channels within the 2.4-GHz band of an 802.11b/g access point radio. This feature allows you to scan only the channels on which tags are usually programmed to operate (such as channels 1, 6, and 11).

How to Optimize RFID Tracking on Access Points

Optimizing RFID Tracking on Access Points (CLI)

SUMMARY STEPS

  1. ap name Cisco_AP mode monitor submode none
  2. ap name Cisco_AP dot11 24ghz shutdown
  3. ap name Cisco_AP monitor-mode tracking-opt
  4. ap name Cisco_AP monitor-mode dot11b {fast-channel [first_channel second_channel third_channel fourth_channel]}
  5. ap name Cisco_AP no dot11 24ghz shutdown
  6. show ap monitor-mode summary

DETAILED STEPS

  Command or Action Purpose
Step 1

ap name Cisco_AP mode monitor submode none

Example:

Device# ap name 3602a mode monitor
 submode none

Specifies the monitor submode for the access point as none.

Note 

A warning message indicates that changing the access point's mode will cause the access point to reboot and prompts you to specify whether you want to continue by entering Y.

After you enter Y, the access point reboots.

Step 2

ap name Cisco_AP dot11 24ghz shutdown

Example:

Device# ap name AP01 dot11 24ghz shutdown

Disables the access point radio.
Step 3

ap name Cisco_AP monitor-mode tracking-opt

Example:

Device# ap name TSIM_AP1 monitor-mode
 tracking-opt

Configures the access point to scan only the Dynamic Channel Assignment (DCA) channels supported by its country of operation.

Note 

To disable tracking optimization for an access point, enter the ap name Cisco_AP monitor-mode tracking-opt no-optimization command.

Step 4

ap name Cisco_AP monitor-mode dot11b {fast-channel [first_channel second_channel third_channel fourth_channel]}

Example:

Device# ap name AP01 monitor-mode dot11b
 fast-channel 1 2 3 4
Chooses up to four specific 802.11b channels to be scanned by the access point.
Note 

In the United States, you can assign any value from 1 to 11 (inclusive) to the channel variable. Other countries support additional channels. You must assign at least one channel.

Step 5

ap name Cisco_AP no dot11 24ghz shutdown

Example:

Device# ap name AP01 no dot11 24ghz shutdown

Enables the access point radio.
Step 6

show ap monitor-mode summary

Example:

Device# show ap monitor-mode summary

Displays all the access points in monitor mode.
