Product Overview

The Cisco Aironet 802.11g Radio Module allow 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.
