Wi-Fi based Long Distance (WiLD) networks have the potential to provide connectivity at substantially lower costs than traditional approaches. However, it is well known that the standard CSMA/CA MAC protocol used by Wi-Fi is not well suited for long distances. To achieve better performance, some researchers have proposed replacing the standard CSMA/CA MAC with a TDMA based MAC, so in this paper, going to show the difference and limitations between using CSMA and TDMA technique.
