Enabling 802.11 a/n/ac and 802.11 b/g/n

802.11 a/n/ac and 802.11 b/g/n helps improve Radio Resource Management (RRM).

This section provides the best practice for Radio Configuration. You must design your wireless network taking into account wireless clients with lower capabilities to ensure that all device types are accommodated. For more information, refer to Power.
Note: Update the Cisco WLAN Controller software to the most recent version available. For more information on the latest recommendations on Cisco WLAN Controller software versions, contact Vocera Technical Support. If you are running Cisco Wireless LAN Controller, you can use RRM by specifying maximum and minimum power level assignments.

To configure 802.11a/n/ac or 802.11b/g/n on a Cisco Unified Wireless Network for the Vocera VLAN, perform the following task:

Note: The steps to configure 802.11a/n/ac or 802.11b/g/n are the same.
  1. Click Wireless to access the All APs page.
  2. Navigate to 802.11 a/n/ac or 802.11 b/g/n >RRM>TPC.
  3. Under Tx Power Level Assignment Algorithm>Power Level Assignment Method, select the following options:

    • Power Level Assignment—Automatic.

      Note: Vocera does not recommend Fixed Power Level Assignment Method. However, if a static power is desired, a static power assessment is required, and power levels should be in the range recommended by Vocera. For more information, refer to the Cisco documentation for the maximum transmit power levels settings of your access points.

    • Power Threshold (-80 to -50 dBm)— -70dB.

      Power changes are only made when an AP's third loudest neighbor is heard at a signal level higher than the default value of -70 dBm.

  4. Click Apply.
    Your changes are committed.
  5. Click Save Configuration.
    Your changes are saved.
  6. Configure 802.11 b/g/a data rates that are supported.
    The following screenshot provides the parameters that must be enabled.
  7. Disable lower data rates for maximum reliability. You must enable one Mandatory higher data rate. Data rates are selected based on sites.
  8. Perform a voice quality site survey to ensure proper network coverage before installing Vocera.

Configuring Coverage

To configure coverage for 802.11 a/n/ac or 802.11 b/g/n, perform the following task:

  1. Click Wireless to access the All APs page.
  2. Navigate to 802.11 b/g/n>RRM >Coverage or 802.11 a/n/ac>RRM >Coverage page as show in the following screenshot.
  3. Specify the following settings for Coverage Hole Algorithm.

    • Voice RSSI (-60 to -90 dBm)—-70.

    • Min Failed Client Count per AP—12.

  4. Click Apply
    Commits your changes.
  5. Click Save Configuration
    Saves your changes.
    Note: Wait for at least 60 minutes after enabling dynamic power level assignment to allow the WLAN to stabilize.
    Each WLAN has its own unique characteristics, based on the structural features of the facility, density of APs, activity levels, and many other factors. Therefore, achieving optimal coverage is an iterative process. The goal of this iterative configuration process is to have the APs transmit power set to level 3 under normal conditions.
  6. Verify AP transmit power levels and coverage.
  7. Adjust transmit power threshold setting using the CLI, and the Coverage and Client Min Exception Level settings until you achieve proper coverage throughout the site, if required.
