The Cisco Aironet 1200 Series is specifically designed to protect current and future network infrastructure investments. The 802.11a radio supports data rates of up to 54 Mbps on eight non-overlapping 5 GHz channels to offer high performance as well as maximum capacity and scalability. The 802.11g radio supports data rates up to 54 Mbps in the 2.4 GHz band. When using an 802.11g radio, the access point may be configured to support only 802.11g clients for high-bandwidth applications, or, for added investment protection, it may be configured to support both 802.11g and legacy 802.11b clients.
The 1200 Series provides the flexibility to change capabilities as customer requirements and technologies evolve. CardBus-based 802.11a upgrade modules can be easily installed into Cisco Aironet 1200 Series Access Points originally configured for 802.11b or 802.11g. The 802.11b Mini-PCI radio module in installed Aironet 1200 Series access points can be replaced with an 802.11g upgrade module to provide increased performance with complete backward compatibility.
