IEEE 802.11a/b/g/n Indoor Coverage and Performance Comparison

There are several IEEE 802.11 variants to interconnect several wireless devices. Usually, a variant is chosen based on their bandwidth and their coverage area. However, sometimes, there are special cases where the best technology is not the newest one. E.g., in the case where devices are going to transmit at a maximum of 1 Mbps, any choice is acceptable. In this paper, we are going to compare IEEE 802.11a/b/g/n in indoor environments in order to know which technology is better. This comparison will be taken in terms of RSSI, coverage area, and measuring the interferences between channels. This study will help the researchers to choose the best technology depending of their deploying case and we will see that the best technologies for in indoors are IEEE 802.11b and IEEE 802.11n.
