Speech and Video Transmission Over Wireless ATM Networks

Abstract

The increasing importance of portable computing/telecommunications applications has motivated the studies on broadband wireless network technologies such as wireless ATM (asynchronous transfer mode) or WATM. Orthogonal frequency division multiplexing (OFDM) is especially suitable for high-speed communication due to its resistance to inter symbol interference ISI. This paper describes an ATM network with wireless access for multimedia communications. The network has been specifically designed to serve as a testbed on which evaluate the effect of OFDM wireless channel. The paper overviews and simulates the ATM technology concepts and the requirements of wireless ATM from mobility and modulation technique
