Marketing Information

Cisco Aironet IEEE 802.11a Cardbus Radio Module provide an easy, cost-effective means to increase the capacity of your wireless network with a simple radio upgrade. An Allen wrench, supplied with the upgrade kit, is all you need to access the CardBus slot to upgrade a Cisco Aironet 1200 Series access point. Simply remove the existing 802.11a radio or remove the slot cover, and insert the new 802.11a module and upgrade the access point's IOS image. The access point does not need to be removed from the installed position and the installer does not need to be grounded while performing the upgrade. No other steps are required.
