Realize Measurable Cost Savings
By using Cisco WCS adaptive power management to turn the access point radios on or off at
scheduled intervals (hour, day, and week) you can reduce your power requirements, carbon
footprint, and operating expenses. The power savings gained will vary based on the Cisco Aironet
access point model deployed (Table 1).
