Introduction
Cisco Aironet Access Points are wireless LAN transceivers that can act as the connection point between
wireless and wired networks or as the center point of a standalone wireless network. In large
installations, the roaming functionality provided by multiple access points enables wireless users to
move freely throughout the facility while maintaining uninterrupted access to the network.

Your 1200 series access point can contain two radios: a 2.4-GHz radio in an internal mini-PCI slot and
a 5-GHz radio module in an external, modified cardbus slot. The access point supports one radio of each
type, but it does not support two 2.4-GHz or two 5-GHz radios. You can configure the radios separately,
using different settings on each radio.

The access point uses a browser-based management system, but you can also configure the access point
