Capacity Coverage & Deployment Considerations for IEEE 802.11g

• Tags:
• mobile - wireless communications

Overview 802.11g is an exciting new technology that offers additional performance, while providing investment protection for 802.11b clients through backward compatibility. By using previous technologies and economies of scale, 802.11g devices are available at little or no additional cost relative to 802.11b. As such, there are many reasons to begin migrating from 802.11b to 802.11g. 802.11g is not, however, a panacea for WLAN capacity issues. When operating in mixed-mode environments, the throughput and capacity improvements are very modest. Even with advances like CTS to Self and when operating in 802.11g-only mode, capacity will be limited by the small number of available 2.4 GHz channels.
