Abstract	A medium access control protocol is proposed for the integrated voice and data services in the local wireless networks, and the performance of the proposed protocol is analyzed. Uplink channels for the proposed protocol are composed of time slots with multiple spreading codes per slot based on WB-TD/CDMA. The proposed protocol uses spreading code sensing and reservation schemes. This protocol gives a higher priority to the delay-sensitive voice traffic than to the data traffic. When a talkspurt begins, the voice terminal reserves an available spreading code to transmit multiple voice packets. On the other hand, whenever a data packet is generated, the data terminal transmits the packet over one of the available spreading codes that are not used by the voice terminals. In this protocol, the voice packets do not come into collision with the data packets. The numerical results show that this protocol can increase the system capacity for voice service by applying the reservation scheme. The performance for the data traffic will decrease in the case of the high voice traffic load because of its low access priority. But it shows that the data traffic performance can be increased in proportion to the number of spreading codes.
