At this point the Cisco 5520 Wireless Controllers are end of life as a Cisco product, so I would not recommend them to anyone looking to purchase a wireless controller for an enterprise. However, many people are still using these, and they do work reliably, even if they are a bit long in the tooth now.
As any Cisco Aironet Access Points, the 3800 model is more for power users than beginners. It is for sure very more complex to maintain and trouble shoot than solutions like Cisco Meraki APs.
By the way, there are a lot of settings that can be customized and it is really interesting for difficult environments like industrial factories.
The 3800 model is also robust so it should stay durable and reliable.
But if you want to use the mesh mode or make a wireless bridge, this model is not appropriate as it is not supported for now.
We have had some issues with access points losing their configurations and going offline. This is not a common issue and we are not entirely certain if it is a fault of the controller or the individual APs. That said, the controller does not appear to retain the knowledge of the offline AP which can be a management headache.
This equipment from Cisco has been dependable and we are able to easily continue to add access points or make changes easily to the Wi-Fi password settings.
We have been operating this equipment for a number of years and it does not give us any issues.
Overall the usability is ok. The centralized management reduces complexibility and offers bulk features like adding access points to specific groups which automatically applies linked configurations.
On the other hand the GUI is very outdated and some features are not displayed correctly on new browsers. Also automation possibilities are very limited compared to the new 9800 series controller.
The Cisco 3802 product performance is excellent. Not only for the speed and range of the wireless it provides, but also for the fact that - when deployed in a large scale environment - the performance does not fail. It provides the same network connectivity for users ranging from 1 to 30-plus concurrent connections.
Cisco support is always ready to support and engage in any problem or issue. Starting from the implementation support, troubleshooting any software issue or hardware. Their engineers are engaging whenever we ask for support, keep following up with us, and troubleshoot any problem till we find a solution and be satisfied [with] the service.
Just take your time when setting up the HA pairs as those can be tricky. Also take your time setting up AP groups and make sure they are on all the SSIDs you need to be on.
Cisco Identity Services Engine is well integrated on Cisco 5520 Wireless Controller because the WLC supports a lot of authentication methods and security protocols (such as PEAP, EAP-TLS, Captive Portal redirect). They perform very well with ISE. Cisco ISE is able to manage centrally the AAA sessions from all the WLCs keeping a central point of management for wireless infrastructure.
The usage scenario was different. I don't see this as a benefit versus harm comparison, necessarily. What happened was that, at a certain point, the implementation of the cisco solution was the winner of our public bidding process and with that, we implemented it and have used it ever since.
Contrary to a solution like the Cisco Meraki access points, the Aironet access points like the 3800 are linked to the Controler. And depending on the version of the controller, it will support only some models of access points.
For big sites, it may be difficult to upgrade the controler to support new ap models like 3800 because we still have old access points.
And it is also the same between new access points and old client devices so it is always a bit tricky.
After that, if the access point model is supported by the controller, it is really simple to install a new one
Implementing the [Cisco] 5520 [Wireless] Controllers offered us a huge improvement in administrative time over our previous Cisco 3850 deployment. Being able to see all of our APs on a single controller as well as centrally manage them is a great benefit. This also removed the need to deploy specific equipment in different IDFs throughout our Industrial locations and instead only requiring switches with Power Over Ethernet (POE) capability.
Wireless performance has improved with the deployment of our 5520s, which allows our plant operators to do their jobs more efficiently while on the move.
Having three Cisco 5520 Wireless Controllers provides tertiary redundancy for our wireless networks. The solution is elegantly simple. Preventing downtime is, obviously, a profound part of our supply chain capabilities.
Users are able to carry on with their work while moving, changing seats, rooms or having an ad-hoc Skype meeting on the way to lunch. It is always hard to justify the value of connectivity but be assured, when it is not working the business impact is immediate.
