Abstract : Wireless networks have made significant advancement in recent times by adding a new dimension to the way people communicate. Development of wireless standards have constantly aimed at providing higher data rates even under complex environments using smart antennas, multiple-input, and multiple-output systems. This has necessitated an understanding of the indoor propagation channel. Channel models describe a communication channel and are essential in developing efficient wireless communication networks. This paper surveys different channel models used to characterise wireless indoor environment. This survey may be useful for the army, where the communication over wide areas during wargames that they hold periodically, is necessary. Moreover, it may also be useful for communication near the border areas for surveillance operations.
