Summer WiFi upgrade to strengthen network

WiFi6 Migration IMG
While campus is quieter this summer, UAB IT is embarking on a WiFi upgrade that will strengthen the network’s redundancy and allow greater scalability as the growth of internet-connected smart devices continues to expand.

UAB IT’s network services team will upgrade the WiFi infrastructure to the latest technology, including a cluster of controllers operating under a virtual server that uses artificial intelligence to help monitor and make adjustments based on network traffic and number of devices connected. On a typical day during the school year, the WiFi network averages more than 14,000 connected devices.

The upgrade will also increase the memory on the controllers, which paves the way for greater capacity.

UAB IT has already begun testing the new configuration and has found improved stability.

“If one controller is affected, you won’t notice on the rest of the network,” said David Wolford, network engineer. “We have also seen greater stability for VPN users.”

A series of nine maintenance windows for the upgrade will begin Friday, June 7, and is scheduled to continue through July 19. Maintenance windows will occur at night and are not likely to impact campus, although there may be brief internet outages of about five minutes.
