    Abstract

    This letter is concerned with the assessment of channel access mechanisms for indoor 3G mobile communications systems offering packet based services. One such service in which the channel access mechanism will have a significant impact is Voice Over Internet Protocol (VOIP). This letter considers the impact of two channel allocation schemes for the indoor environment: mobile-controlled dynamic channel selection (DCS), and basestation-controlled inhibit sense multiple access (ISMA). It is shown that the DCS scheme is subject to inferior performance in packet based voice transmission due to a higher degree of front end clipping which is introduced.
