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.

Extreme Networks' Wireless Access Points (or ExtremeWireless) are designed to provide performance in the most demanding environments with the latest Wi-Fi technologies including 6 GHz, OFDMA, MU-MIMO, and software-defined dual 6 GHz radios.
I consider that its implementation is recommended for configurations where the amount of access points exceeds 50 devices and the performance exceeds 4 Gbps. In environments where the access point density is less than 10 units, we can use the option of Express Mobility.
The Extreme access point solution has been used in the cooperative scenario with VLANs for employees in access through 802.1x authentication and also for guests through the captive portal that allows access of people for a limited time and prior registration. The equipment has great performance and connection speed and supports a high density of users connected at the same time without lag and crashes. The management of this equipment is being carried out through software with cloud management and is accessed by our infrastructure team to configure and monitor alerts.
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.
In my experience, licensing has become a nightmare. Licensing must be tied to a device, they also won't let you activate used units from other companies if they are donated or purchased third-party.
Customer service is outsourced overseas.
In my experience, technicians are incentivized to close tickets quickly - whether the issue has been fixed or not - which can be frustrating to work with.
Cisco is always available if we need support. If they are unable to solve the problem right away, they will reach back to us in a timely manner and advise what we need to do. Their team provides additional guidance as well if we hit any stumbling blocks. Their service has been great.
Support was always responsive and willing to help, but at times did not know when to call it and send a replacement to stop the bleeding. I respect that fact that they wanted to get the solution working, and the wanting to learn more and understand, but at times you cant do that at the expense of the customer.
Cisco is the most stable company in switching parts including wireless, and it has the most powerful support team with a lot of online documents, community, and market share so when you get stuck, you can find support from anywhere. And usually, you won't need it as its product is very stable and reliable.
The Aerohive wireless devices are comparable to Cisco's wireless solution, in regard to performance, features, and management. But the cost of utilizing Cisco Wireless Access Points versus using the Aerohive access points is staggering. Since our wireless access points do not maintain a constant heavy load, we chose a more cost effective solution and have not had many issues with them.
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.
