Current Approaches for Extending Range of Wi-Fi Network

Nowadays, Wi-Fi networks have numerous emerging applications, ranging from backbone Wi-Fi networks, last-mile wireless networks and Wi-Fi direct networks. We can categorize the application into two types: (1) indoor wireless networks and (2) outdoor wireless networks. Indoor Wi-Fi networks include wireless networks and Wi-Fi direct networks, which usually have shorter links than outdoor wireless networks. Compared with indoor wireless networks, outdoor Wi-Fi networks attend as the network backbone or the infrastructure for Internet connection and usually have a longer transmission range. Besides, a data transmission usually traverses through multiple expectancy in outdoor wireless networks while it often takes only one expect in indoor wireless network. The distance limitations and data rates with Wi-Fi networks are more arduous to calculate due to varying data rates, capacity, interference, etc. In this paper, we discuss the various methodologies for increasing range of Wi-Fi network.
