AirWave is licensed by the number of managed infrastructure devices: APs, controllers, switches, etc.
Licenses can be purchased in bundles of 25, 50, 100, 200, 500, 1000, and 2500. Licenses can be combined (150 devices can be managed with AW-50 plus AW-100, 5000 devices can be managed with 2 x AW-2500).
Customers can deploy the licenses on as many servers as are necessary to manage their infrastructure, so one AW-2500 can be used to managed 1250 devices on two different servers. Expansion licenses are also available to buy an exact number of APs for gradual network expansion or to take advantage of discounted pricing for purchases over 2500 devices.
