ExtremeWireless is an on-premises solution. We offer the ExtremeWireless controller solution to customers who want an on-premises solution to do some configuration without much exposure to the cloud platform. With the solution, you can have the local controllers and APs on-premises and do stack configuration. Even if you have multiple branches where you can deploy APs only in FlexConnect mode, they will remotely connect to the controller. One of the branch APs will act as a controller or RF Domain manager and send all the information to the central controllers in a different location.
This process will reduce the cost a little bit for customers who can't afford all sites in each individual controller. The AP will act as a controller and connect to the central controller, providing all the controller functionalities for the local site. Even if the central controller is down, the local controller APs will be up and running. Compared with Cisco or Aruba, ExtremeWireless offers the best on-premises controller solutions we like.
ExtremeWireless has more compatibility with barcode scanners when compared to other solutions. The solution provides more flexibility and compatibility to organizations using warehouses.
