Abstract: The provision of multimedia services to a wireless environment presents several technical challenges. The extension of these services to a survivable, distributed system adds a significant level of complexity. Packet radio network technology offers one possible starting point for a solution. This thesis approaches the problem of delivering integrated voice, low grade video and low rate data services to a wireless network operating in a distributed environment through the use of a packet radio architecture. An overview of the technical specifications to be addressed in the network design is used to define the operational requirement. A radio channel model based on the Hata-Okumara approach is then developed in order to provide a realistic simulation framework for the system and a basis for network connectivity maps in subsequent chapters. The issues related to the operation of a distributed network are then explored, essentially illustrating the design implications of survivability. Several different multiple access techniques are also evaluated for suitability in this network design. Based upon the criteria provided at the onset, a slotted CDMA methodology is recommended. This leads to the establishment of network control parameters including the data structure, routing and scheduling schemes based on slotted CDMA operation in a distributed environment. Finally, issues related to network integration and enhancements are discussed, including CDMA code orientation, control channel modifications and acknowledgements. Recommendations for future work are also provided.
