Design and performance analysis of an integrated voice/data mobile radio system

A design and performance analysis of an integrated voice/data mobile radio system is presented. The centerpiece of the design is a special switching technique, called packetized data, voice dedicated (PDVD) burst switching, which places data in the silence gaps inherent in speech. System performance is analyzed via computer simulations, which show that a voice-only mobile radio system can be upgraded to an integrated voice/data system without requiring additional radio channels and without compromising voice performance. The data traffic is only minimally delayed (46.2 ms mean delay for a fully loaded system). The integrated voice/data mobile radio system can also accommodate a 100% growth in data traffic and still perform with very acceptable data delays. The most significant portion of the data delay is due to contention among multiple data packets; thus, data delay can be further reduced by implementing improved contention control techniques.<
