Cisco 8540 Wireless Controller

We use our Cisco 8540 Wireless Controller to implement a fully ubiquitous wireless network on our Main Campus, and multiple branch offices. The controller allows us to broadcast our corporate (private) network, secure guest network access, along with numerous other networks that allow separation of network traffic. We also use our controller to provide a more private method of access for field engineers in certain locations (as opposed to using hot spots or cellular connectivity).

We have a N + 1 deployment of Cisco 8540 Wireless Controller. We have over 8000 Cisco Access Points that are connected to the controller.

• The Cisco 8540 Wireless Controller allows you to reduce your hardware footprint of wireless controllers deployed in your environment. Instead of having a controller per site deployed, you can have a couple of 8540 controllers in your data center that can handle up 6000 Access Points.
• Some of the savings on hardware cost is offset by the cost of redundant WAN circuits. The access points will continue to function when connectivity to the Cisco 8540 Wireless Controller is unreachable, but it will not allow any new connections in that wireless environment.

Since its beginnings, the Cisco 8540 Wireless Controller has served as our router for wireless connectivity to the company's networks. We use it throughout the organization and have solved spare capacity and cloud connectivity concerns for critical components, such as servers and databases. Cisco [8540] Wireless Controller is the most comprehensive and it’s what I’ve been using. As compared with other manufacturer's products, it offers advanced functionality and integration. It comes with excellent documentation and is easy to understand. Even the oldest controllers can still support the latest APs. It works thanks to the Cisco infrastructure. It can deliver high performance when the Wi-Fi tuning is done correctly.

• It distributes system ports, security features, and support for multiple protocols.
• [It provides an] AP-manager interface with high bandwidth availability for all APs, even during peak times.
• [The] dynamic interfaces are unquestionably present.

• This device has allowed for time and cost savings for the organization since its installation.
• It's a simple enhancement to an existing network that provides security protection, which can have a significant impact on any business.
• It helps reduce staff costs and works well in conjunction with other Cisco products.

The [Cisco 8540 Wireless Controller]s are being implemented and are used across

our organization. It has solved our problem of weak and slow internet. After

using Cisco Router, we are having fun with the fast speed network access [now that] it has become easy for us to perform our tasks. In short, it is a

perfect solution to address all the network-related business problems like

security.

• We can easily manage the router protocols.
• Reliability of the network [is an important feature].
• The way we can control and limit network traffic [is an important feature].

• We get fast speed network access.
• We get reliable and secure network access.
• The network management is much [more] advanced and we can control the unwanted traffic.
• [In my opinion, the] long installation time and pricing have brought a negative impact on our business.
