Cisco AIR-AP1231G-A-K9 Wireless Access Point Networking

The mini-PCI interface supports either an IEEE 802.11b or 802.11g
radio operating in the 2.4 GHz frequency band. The CardBus
interface supports an IEEE 802.11a radio operating in the 5 GHz
frequency band. At least one radio must be installed for the access
point to operate in a WLAN, and at most, two radios (one of each
form factor) can be installed.
Cisco Aironet 1200 Series modular access points feature antenna
connectors for greater range or coverage versatility using a broad
selection of available Cisco antennas, as well as a rugged, metal
housing for operation over extended temperature ranges typical of
demanding environments. The 802.11g radio delivers industry-leading
range and throughput, meeting the performance requirements of
industrial and enterprise applications, while hardware-assisted AES
encryption provides uncompromised support for interoperable IEEE
802.11i and WPA2 security. While the 802.11g-configured Cisco
Aironet 1200 Series meets the needs of many industrial
applications, its modular design allows dual radio configuration
and field upgradeability so administrators can deploy a wireless
network optimized for their evolving requirements. The Cisco
Aironet 1200 Series supports Cisco IOS Software and is a component
of the Cisco SWAN framework, a comprehensive framework that
delivers an integrated, end-to-end wired and wireless network.
