A supervisory control and data acquisition (SCADA) digital wireless wide area network (DWWAN) which is adapted to power utility grid has been designed with an architecture consisting of 56 nodes (28 links) stretching over a rugged mountainous zone. Simulation is conducted for design parameters such as tower heights, total antennas per tower, path l...

... obtained results. Diversity reception is needed only in link {L24 (24A, 24B)} and space diversity is undertaken with separation between antennas (3.0 m, G = 38.8 dB) as 8 m. (IV) All link performance are compared with the compliance of the ITU-T G.826 target. Path profiles have been simulated for all the 28 links with a typical profile shown in Fig. 8 for L24, which shows terrain heights and the three rays for the carrier propagation assuming an antenna clearance (1.0, 0.6, 0.6) of the first Fresnel Zone radius (F1) from the multipath propagation. The DWWAN radio link antennas are usually placed at considerable heights above ground level, to extend the radio horizon and the link ...
