| Abstract: | Private land mobile communications have experienced significant demand for increased capacity and for new services, but congestion within the currently allocated 150 and 450 MHz bands has severely limited the capability of present generation systems to meet this demand. The authors show the use of a transEuropean trunked radio system (TETRA) standard to provide a telecontrol service for a medium size power utility. They introduce the concepts of TETRALAN architecture to support communications inside a substation, and TETRAWAN architecture as the backbone radio network. Finally, system performance is increased by using the silence gaps inherent in speech |
