In the past decades, the Wi-Fi technology has experienced exponential development, and has now become very popular as laptops, tablets, smart phones, and other mobile devices emerge and are used extensively. While Wi-Fi networks offer many advantages over typical wired Local Area Networks (LANs), such as convenience and mobility, they also present several drawbacks. One of them is the limited range. Wi-Fi signals are carried on radio waves, which lose strength with increasing distance. The typical range of a common IEEE 802.11b or 802.11g network with standard equipment is on the order of tens of meters, although the newer 802.11n standard networks deliver more than double that range.
