VLANs Deployment

  • The Wireless Controller must have IP connectivity with the access points through the management VLAN. If the Controller and the APs are on different management VLANs, external VLAN routing must allow IP connectivity between the Controller and the APs.


Integrated Deployment Planning

  • Hierarchical view of the network: Floor maps upload and floor maps dimensions input
  • Automated RF planning algorithm: Computed number of APs required to cover a floor plan
  • Theorical cloud coverage indicated for each AP for positionning assistance on the floor plan

RF Monitoring

  • Coverage computing per floor plan
  • Alert for any detected coverage holes with mitigation options with neighboring APs
  • Rogue AP/blacklisted clients triangulation

  • 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

Rate Limiting

  • Rate limit per SSID set as a percentage of total available bandwidth
