Cisco 5520 Wireless Controller vs. Cisco 8540 Wireless Controller

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.

I recommend using Cisco 8540 Wireless Controller as an economical solution for assurance of best wireless connectivity across departments and cloud resources. It can resolve most of the networking and cloud connectivity-related issues. It can also eliminate the issues related to bandwidth. It can provide uninterrupted connectivity to cloud resources and databases at high speed with security.

• It has the ability to manage all Cisco access points that we have, regardless of the model. The limit is 1500 pieces of equipment.
• The WLC enables roaming functionality in the localities, this helps with collections, wireless IP phones, and access with notebooks.
• The WLC manages the quality of the "air" and "signal" of the 2.4ghz frequency, avoiding noise and interference.
• The WLC has an interesting feature of visibility of the traffic of the internal network.

• The GUI on the Cisco 8540 WLC is much better designed than other Cisco products. Its easy to navigate between the different settings to find what is needed.
• The AP groups allows touching multiple APs at one time.
• It also allows us to create standard SSIDs that can be used at all sites that connect back to it, this saves a lot of time instead of hitting each site with a local controller.

Incentivized

• [It] can improve on the possibility of using the physical controllers with the virtual one.
• [It] can improve on the possibility of having site-to-site failover capabilities, [like in the case of] controllers at production go down and controllers at our DR site take over.
• The possibility of an app on your phone for alerts and minor configuration of the controllers.

• Code quality is a bit hit and miss. This will be great for a while, then things will be bad for a while, then we'll do it again. The UI of the controller works, but could do with a refresh, and I would like to see some improvement on layout and organization.
• The constant code/firmware upgrades and the QA of new code could be better.
• Maybe the compatibility with old Cisco Access Points could be improved, but it's normal in all kinds of deployments.

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.

Very feature rich, easy enough for beginners to understand layout and initial setup. Need a good training (online, Cisco Leaning Network, etc.) to fully understand all features and product capabilities. Strict power requirements for APs are only major drawback for our specific implementation.

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.

It is a better product. The evolution is positive.

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 5520 Wireless Controller has better high availability features compared to the others. Also Cisco has a worldwide service center and is located in nearly all countries to offer fast and reliable support in case of any hardware issue. Also Cisco offers more features, for example AVC, CleanAir and TrustSec which the compotitiors don't. And we could use some of our als Cisco APs with the Cisco 5520 Wireless Controller and didn't need to buy that much new APs.

Cisco products offer an unrivaled experience that outperforms the majority of other alternatives. This is a long-term investment that will provide a great return on investment. The Cisco 8540 Wireless Controller, on the other hand, is more powerful and has more features for managing each device and the wireless network.

• [It provides] centralized management.
• 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.

Incentivized

• Network engineers find it easier to [manage] high-stress levels since they're more reliable and robust.
• Their initial cost is very high compared to other router providers, such as Juniper.
• Their hardware dependability can be a big drawback if you run on a budget.
