AP Controller Technology

With the BYOD trend accelerating, Wi-Fi connectivity is now widely provided everywhere in offices, hotels and even schools. This significantly and quickly increases demand for Wi-Fi 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 Wi-Fi networks with less investment and management efforts.

  1. *: Supported from APC1.97 or above.
  2. *: With UAG firmware ZLD4.15 or above
  3. *: Supports APC3.0 in Nov. 2017
  4. *: Available with ZLD4.30 or above
  5. *: From APC3.0, commercial gateways supporting APC technology are able to recognize APs with FW release higher than APC3.0 as Forward Compatible APs. Customers are able to introduce new AP technology with basic features support while staying with existing APC device FW if needed.
