Abstract :
Since its creation in the fall of 1978, Westech Systems Ltd. has been involved in, design, and development of cellular automatic mobile telephone systems to meet the evergrowing market demand for this line of products. The first such system developed by Westech is a custom-designed, 400 MHz band, AURORA System for Alberta Government Telephones (AGT). This system is now in operation in Edmonton, Alberta, and installation work is under way to provide province-wide mobile telephone service by later 1984. To satisfy overseas and other North American markets, Westech has been designing the 800 MHz band version of AURORA, referred to as the AURORA 800 System, and also enhancing the AURORA 400 System to include additional requirements of the world market and also take full advantage of recent advancements in VLSI technology. A brief description of the AGT AURORA System will be presented together with an overview of on-going development work on the AURORA 800 System and planned enhancements to the AURORA 400 System.
