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.
Best in small networks & appropriate in industrial areas. AP works fine in any temperature & location (in remote locations office or remote location). Open area wireless connectivity is good with good range. Simple VLAN management and management are good. Backup and restoration is very good. Small home offices using wireless network work awesome.
Due to multiple switches in a single network environment, communication issues are common; therefore, productivity is effected. After installing D-Link Wireless, we resolved these kind of issues in our network.
One windows solution make management easy via D-Link Wireless.
Logs and troubleshooting is now easily handled. Pictorial form help in configuration and users management.
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.
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.
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.
We studied and selected D-Link due to usage in a limited area, and it is a very cost effective solution; therefore, D-Link Wireless AP and D-Link Wireless Controller [were] selected for our organization. We also [researched] Cisco, but Cisco was an expensive product and not appropriate in our required area or task; therefore, we selected D-Link.
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.
