RF challenges for 2.4 and 5 GHz WLAN deployment and design

With their low cost and high-speed data rate capabilities, IEEE 802.11-based wireless local area networks (WLANs) are growing exponentially. This paper discusses the interference impact from the co-channel interference on current 2.4 GHz WLAN application and addresses several RF design challenges for future 5 GHz frequency band operations. Coverage and migration issues from 2.4 GHz to 5 GHz are also included.
