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.
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.
Any rollout is well suited for a FortiAP - from small office networks, to large warehouse deployments. Adding additional APs to your network is simple and easy. Monitoring is simple with Forticloud monitoring. Configuring the devices can be as complex or as simple as you need. Adding additional Fortinet devices (I have switches and firewalls) makes the network even more secure and easy to manage - all devices working in tandem make monitoring much easier
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.
In the dailies activities it's simple to manage a wireless network and also to perform changes: the GUI is well known and intuitive for engineers that know how to operate on Cisco WLC. It has High Throughput and consolidated features such as CleanAir, Roaming supporting natively Cisco ISE authentication methods and DNA Center. It's recommended for Wi-Fi 5 wireless infrastructures.
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.
[The] best bet is the integration with ISE. Users use their active directory credentials to access the wireless and very simple guest portal to gain access to the Internet. We plan on integrating Cisco DNA Centre in the future that will give us more visibility and improved performance.
I think all Fortinet clients are definitely business level products. Easy to use. Hardens your network against attack. Gives you more visibility into your network at all times. Helps you get a handle on your users and environment. Definitely worth the cost.
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.
