Cisco Aironet 802.11G 1100 and 1200 Series Access Point Upgrade Kit
The Cisco Aironet® IEEE 802.11g 1100 and 1200 Series Access Point Upgrade Kit provides customers with an easy and cost-effective migration path to the IEEE 802.11g standard for high-speed 2.4 GHz wireless networking. Cisco Aironet products set the enterprise standard for high-performance, secure, manageable, and flexible wireless local-area networks (WLANs), and the Cisco Aironet Upgrade Kit delivers upon the Cisco Aironet commitment to protect customers' current and future wireless network investments.

Delivering Investment Protection
The Cisco Aironet 802.11g Upgrade Kit allows customers to take advantage of the new 802.11g technology, with its higher 54-Mbps throughput and its 802.11b backward capability, while continuing to use their existing Cisco Aironet WLAN infrastructures. Because 802.11g and 802.11b operate in the same 2.4-GHz unlicensed band, migrating to 802.11g is an affordable choice for customers with existing Cisco Aironet 1100 Series and 1200 Series access points. As bandwidth and scalability requirements grow, network administrators can strategically migrate existing 802.11b access points quickly and seamlessly as time and budgets allow.

Greater Capacity Made Easy
The Cisco Aironet 802.11g Upgrade Kit provides an easy and cost-effective means to increase the capacity of your wireless network with a simple radio upgrade. A standard Philips screwdriver can be used to upgrade the Cisco Aironet 1100 Series Access Point. An Allen wrench, supplied with the upgrade kit, is all you need to access the embedded radio to upgrade the Cisco Aironet 1200 Series Access Point. Simply remove the existing 802.11b radio, and insert the new 802.11g radio and upgrade firmware. No other steps are required.
