The Cisco 5520 Series Wireless LAN Controller is a highly scalable, service-rich, resilient, and flexible platform that is ideal for medium-sized to large enterprise and campus deployments.

The Cisco Catalyst 9100 Access Points includes the 9115 and 9117, and designed to meet high demand network access.
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.
Cisco Catalyst 9100 Access Points are well suited for dense Client solutions. We have used these in areas where we have a large number of guests that need top-notch connectivity without ever losing connection. The one area where we do have difficulty is in outdoor deployment, where large areas need to be covered, but we do not have physical connectivity in order to get the access points connected. This is not an access point issue but more of a physical connectivity limitation.
So this product actually helps in healthcare facilities where we have a wireless, we call this WOW monitors. It's Wireless On Wheels. So we use those monitors to the patient's room to room. So in that case, rather than connecting it to wire, so it really helps us to connect through the WIFI and access the patients whenever we be needed.
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.
They could definitely download their code faster. When we first get them out of the box and join them on the network, it takes probably 20, 30 minutes per access point to download the new code from the wireless controller and then reboot itself and then come back online.
When you're configuring it on the controller, if you want to switch access point groups, we have them broken out per site. Every time you add it to one of those groups, it also has to reboot. That's like downtime for us. That could be improved, I think.
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 Catalyst 9120 Access Points have been a solid deployment for me. Using their interface is a mix of new and old. They run IOS, so if you know the CLI, you can easily navigate around them. You can join them to an older controller if it supports a certain version, you can join it to a new 9800 controller--very straight forward--and you can run the embedded wireless controller on them directly. I've found this to be very useful at smaller sites. The Cisco Catalyst 9120 Access Points are not limited to feature sets like the older generations' mobility express platform.
Using Cisco Catalyst 9100 Access Points you can expect good performance, if not excellent. Coupled with other tools and managment systems you can easily gain good insight and ease of management. Flexible deployment variations help you adopt the equipment to work for most any required scenario you could think of. It's a well designed and evolved product.
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.
Cisco has been very good at correcting early issues with their code. Their TAC support has been fantastic when I would open a case with issues I was facing. Even though the hardware was new, they were very familiar with the interfaces and issues I was having. In the past I've been concerned about adopting a new product right away because of support issues. That was not the case here. Once I had the deployment up and running, they have had a good run of reliability.
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.
We are migrating from Aironet platform to Cisco Catalyst 9100 Access Points. That's more flexible, and we do it to sync switching, SDWAN, and wifi under one family.
These access points offer flexibility in deployment scenarios, supporting both standalone and controller-based architectures. Organisations can choose the model that best suits their current needs and scale as their requirements grow. Cisco Aironet Access Points are compatible with Cisco's Wireless LAN controllers, allowing for centralized management and monitoring of a large number of access points across the network. With the recent changes, it will even support cloud base controllers.
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.
