The file AIR-AP2800-K9-ME-8-8-130.0.tar is a primary software bundle. It contains the necessary images to convert a standard AIR-AP2802E-B-K9 to function as a Mobility Express controller.
In 2026, the 2800 series is nearing its end-of-support (October 31, 2027), making it a popular choice for budget-friendly, high-performance SMB deployments.
Starting with version 8.3, the Master AP can act as a DHCP server, though it is primarily recommended for site surveys. Scale Limits: A 2800 Series AP acting as the "Master" can support up to 2000 clients

: If downgraded to Release 8.1, certain associated Wave 2 APs (like the 1850 series) previously running in "Sensor" mode will fall into an "unknown" error state since that mode was not yet recognized in version 8.1. Cisco Mobility Express for Aironet Access Points
Newer Cisco Mobility Express firmware iterations (such as versions 8.5 through 8.10) feature expanded capabilities, pushing their individual file footprints well over 53MB to 65MB.
: Cisco’s controller-less deployment architecture . Mobility Express allows a single, designated Master Access Point to act as a virtual Wireless LAN Controller (WLC), managing up to 100 additional APs on the same subnet without requiring dedicated controller hardware.
