  • Page 57: Multiple Data Streams - Spatial Multiplexing

    Wireless Array Multipath signals were considered to be interference by 802.11a/b/g radios, and degraded performance. In 802.11n, these signals are used to enhance performance. This extra sensitivity can be used for greater range or higher data rates. The enhanced signal is the processed sum of individual antennas. Signal processing eliminates nulls and fading that any one antenna would see.

  • Page 58: Channel Bonding

    Wireless Array Channel Bonding Channel bonding increases data rates by combining two adjacent 20 MHz channels into one 40 MHz channel. This increases the data rate to slightly more than double. A bonded 40 MHz channel is specified in terms of the Primary channel and the adjacent channel to Bond.

     Some features, such as Netflow, are only available if the Array’s license includes the Xirrus Advanced RF Analysis Manager (RAM). If a setting is unavailable (grayed out), then your license does not support the feature. See “About Licensing and Upgrades” on page 321.

  • Page 195: Figure 105. Wi-Fi Tag

    Wireless Array Wi-Fi Tag This window allows you to enable or disable Wi-Fi tag capabilities. When enabled, the Array listens for and collects information about Wi-Fi RFID tags sent on the designated channel. These tags are transmitted by specialized tag devices (for example, AeroScout Tags).
  • Page 196 Wireless Array System Log This window allows you to enable or disable the Syslog server, define primary, secondary, and tertiary servers, set up email notification, and set the level for Syslog reporting for each of the servers and for email notification — the Syslog service will send Syslog messages that are at the selected severity or above to the defined Syslog servers and email address.
  • Page 197 Wireless Array Local File Size (1-2000 lines): Enter a value in this field to define how many Syslog records are retained locally on the Array’s internal Syslog file. The default is 2000. Primary Server Address (Hostname or IP) and Port: If you enabled Syslog, enter the hostname or IP address of the primary Syslog server.
  • Page 198 Wireless Array Syslog Levels: For each of the Syslog destinations, choose your preferred level of Syslog reporting from the pull-down list. Messages with criticality at the selected level and above will be shown. The default level varies depending on the destination. Console Logging: For messages to be echoed to the console, the default level is Critical and more serious.

  • Page 199: Figure 107. Snmp

    Xirrus MIB, available at support.xirrus.com, in the Downloads section (login is required to download the MIB). NOTE: If you are managing your Arrays with XMS (the Xirrus Management System), it is very important to make sure that your SNMP settings match those that you have configured for XMS.
  • Page 200 SNMPv2 Settings Enable SNMPv2: Choose Yes to enable SNMP v2 functionality, or choose No to disable this feature. When used in conjunction with the Xirrus Management System, SNMP v2 (not SNMP v3) must be enabled on each Array to be managed with XMS. The default for this feature is Yes (enabled).
