Simulation is conducted for design parameters such as tower heights, total antennas per tower, path loss, rain attenuation, hop lengths and power budgets that fulfill ITU standards for availability per year. Path profiles have been simulated employing a topographic database and Global Positioning System (GPS) coordinates of the designated node sites. The radio channel is assumed as a SDH digital path employing fixed or adaptive MQAM modulation scheme with Rician fading processes. The Rician fading channel equations are established for the symbol error rate and the spectral efficiency. Such networks can deliver channel capacities up to 2×155.52 Mbit/s per single frequency pair employing co-channel double polarization (orthogonal beams) with a bandwidth of 29 MHz and a gross spectral efficiency in the range of 5-11 bits/sec/Hz. This architecture gives network operators a spectrum efficient solution and can be integrated with mobile cellular backbone networks.  ISSN : 1319-1047  Journal Name : Engineering Sciences Journal  Volume : 22  Issue Number : 1  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Monday, December 12, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email أحمد عباس عدس Adas, Ahmed Abbas Researcher Doctorate aadas@kau.edu.sa Files File Name Type Description  31647.pdf pdf SCADA Wireless Wide Area Networks Back To Researches Page
