Automatic Channel Allocation

  • Channel automatic distribution to reduce interference
  • Auto-channel allocation takes into consideration the AP location, interferences, and neighborhood maps for each AP
  • Modifiable list of corporate channels to be used
  • Scheduled mode for auto-channel allocation
  • Automatic mode available in case of high level of interference

Automatic Power Control

  • Optimum transmit power determination based on coverage requirements
  • Automatic power control mode available
  • Neighborhood scan of RF environment to minimize neighboring AP interference and leakage across floors

Coverage Hole Detection

  • Automatic mode
  • Down APs or compromised RF environment detection with alerts
  • Self healing: Automatic neighboring AP power increase to fill in for coverage losses

Load Balancing

  • AP load monitoring and overload prevention
  • Client redirection to lightly loaded neighboring APs

Fast Roaming

  • Seamless rapid mobility across VLAN and subnets
  • Includes 802.11i pre-auth and fast roaming
  • Fast roaming support accross L2, and L3 for video, audio and voice over wireless client


WMM Quality of Service

  • WMM (802.11e) prioritizes traffic for both upstream traffic from the stations to the access points (station EDCA parameters) and downstream traffic from the access points to the client stations (AP EDCA parameters)

WMM Queues in Decreasing Order of Priority

  • Voice: The highest priority queue with minimum delay, which makes it ideal for applications like VoIP and streaming media
  • Video: The second highest priority queue with low delay is given to this queue. Video applications are routed to this queue
  • Best effort: The medium priority queue with medium delay is given to this queue. Most standard IP application will use this queue
  • Background: Low priority queue with high throughput. Applications, such as FTP, which are not time-sensitive but require high throughput can use this queue

WMM Power Save Option

  • WMM power save helps conserve battery power in small devices such as phones, laptops, PDAs, and audio players using IEEE® 802.11e mechanisms

Storage and Operating Temperatures

    • Operating temperature 0°-45° C (32°-113° F),
    • Storage temperature -20°-70° C (-4°-158° F)


    • Operation 90% Maximum Relative, Storage 95% Maximum Relative
    • ProSafe Lifetime Warranty
    • Next business day onsite hardware replacement support, 3 years (included)
