Cisco 5520 Wireless Controller vs Cisco 8540 Wireless Controller

• Centralized management has been the greatest factor in our preference for the 5520 controllers.
• The web portal administration site is intuitive and granular. We have enjoyed the ease of administration on through the portals.
• We have been very pleased with the effectiveness of Dynamic Channel Assignment (DCA) and Transmit Power Control (TPC) Algorithms. These feature settings (out of the box) have worked nearly flawlessly for us.
