Cisco 5520 Wireless Controller vs Ubiquiti WLAN

• 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.

• The access points are rock solid for uptime. Once configured, they don't skip a beat and you'll forget they're there.
• Excellent range and signal strength.
• Very comprehensive configuration and administration via the UniFi Controller software.
• The Ubiquiti access points look great! Whether wall or ceiling mounted, they are discrete and neutral enough to just blend in with the building.
• Being powered via PoE, it's easier to place the access points where they're most useful.

• Can improve on the possiblilty of using the physical controllers with the virtual one
• Can improve on the possibility of having site to site failover capabilities - controllers at production goes down and controllers at our DR site takes over
• The possibility of an app in your phone for alerts and minor configuration of the controllers

• Management of devices has become much simpler with the UNMS application, but personally, I would like to see some AirMax-like devices from their Unifi line where everything could be managed from an Unifi controller.
• Most Ubiquiti devices are 24V PoE, which is the bane of my existence. I have had several devices fried when staff plugged into standard 48V PoE. They generally don't fail catastrophically, either. You just get strange issues that are difficult to diagnose and eventually need to replace them.
• Devices seem to have trouble with many patch cables/switches. Make sure you certify any patch cables you make and don't over crimp.
• Sending devices from the factory with same 192.168.1.20 IP instead of DHCP makes it a pain to bulk-setup devices.

• The controller redundancy and coverage area is exceptional.
• Quality of service and high level of performance and stability is essential for the organization to deploy it globally.

• it has improved our warehouse's abilities to pick, pack and dispatch faster and more accurate
• Office wide wi-fi signal allows users to work off their laptops almost anywhere in on site.
• The wi-fi has allowed us to reduce mobile data usage on company mobiles as well, as everyone is on the wireless lan instead on 4G
