One of the hottest topics on the minds of our customers for 2018 continues to be their wireless infrastructure. As WLAN 802.11ac wave 2 devices becoming mainstream, Cisco has placed a stake in the ground claiming to be the \u201cvalue leader.\u201d\nCisco's solution to accomplish this is Mobility Express, designed to help companies\u00a0easily set up wireless LAN (WLAN) networks. What exactly is Mobility Express? And is it right for you?\nWhat is Mobility Express?\nMobility Express is the ability to use an access point (AP) as a controller. That means a lightweight network without a controller box. Instead one of the APs on the network acts as the controller. Here is how Cisco describes it:\n\u201cMobility Express integrates wireless LAN (WLAN) controller functions into the Cisco Aironet\u00a0\u00a03800, 2800, 1850, 1830, 1815, 1560 and 1540 Series Access Points. As such, Mobility Express is the latest in a series of Cisco efforts to turn WLAN controllers into a software function that any network component can host. Cisco controller capabilities also can be housed in standalone appliances (Cisco Wireless LAN Controllers, or WLCs), Cisco switches, Cisco routers, a private cloud, and a public cloud.\u201d\nWhich APs can do Mobility Express?\nThe below table lists which APs are supported:\n\nWhich APs can be controlled by a Mobility Express AP?\nThe following APs can be controlled by a Mobility Express AP:\n\nCan the Cisco Aironet 3800, 2800, 1850, 1830, 1815, 1560 and 1540 access points function as WLAN controllers and access points at the same time?\nYes, they can function concurrently as an access point servicing clients, while also hosting the Mobility Express controller function.\nWhat are the management options for Mobility Express?\nMobility Express can be managed by:\n\nCisco Mobility Express Web User Interface\nCisco Wireless mobile application (available at the Apple App Store and Google Play Store free of charge)\nCisco Prime\u00a0Infrastructure, Release 3.0.1 or newer\nCisco command-line interface (CLI) through console cable, SSH, or Telnet\n\nHow many APs can be controlled at a time in Mobility Express?\nIt depends on the AP that is acting as a controller. It used to cut off at 25. Newer code changed that.\n\nLimits to Master AP\nIf there are more than 50 access points in a Mobility Express network, the Master AP (running the WLAN controller function) can service a maximum of 20 clients. This limit applies only to Master AP and not any other access point in the Mobility Express network.\nFeatures not supported by Mobility Express\nOne final bit of customer feedback: When I asked about the downside of going this route, I was pointed to a list of features not supported. And with the help from our product engineer team, I narrowed it down to six (may, or may not be relevant, depending on requirements):\n\nMesh mode\nWorkgroup Bridge (WGB) mode\nIntegrated BLE\nBasic spectrum analysis\nCisco CleanAir\nCisco Wireless ClientLink 3.0\n\nFor more information, visit the Cisco Mobility Express Solution FAQ website.
