Access Point Controller-Technologie

With the BYOD trend accelerating, WiFi connectivity is now widely provided everywhere in offices, hotels and even schools. This significantly and quickly increases demand for WiFi access points, which in turn leads to more provisioning and management issues for network administrators. In fact, a well-designed WLAN controller is usually a solution to relieve administrators from these problems.

Now, Zyxel makes its advanced AP Controller (APC) technology available not only to stand-alone NXC WLAN controllers, but also to its various Gateway products. This enables businesses to easily scale up their WiFi networks with less investment and management efforts.
