Results of estimation of required levels of radiated power of base stations of cellular communications at the voice communication mode on urban area, taking into account attenuation of radio waves in buildings, and levels of intranetwork interference, are resulted. Analysis is made on the basis of behavior simulation of the fragment of GSM network at voice communication mode, executed with the use...
This paper tried to design the implementation of WRAN 802.22 as a new proposed and interesting standard to provide broadband service in tv white space (unused spectrum digital television), specially in hard to reach and low density population area. With the standard parameter WRAN that have been drafted, we calculate the total amount of site needed in Banten, one of the province in Indonesia. In this...
Results of estimation of necessary and sufficient levels of radiation power of base stations of cellular communications on urban area are resulted. Analysis is made on the basis of results of behavior simulation of the fragment of a GSM network executed with the use of multibeam radiowave propagation model X3D and the topological model of a fragment of urban area of the central part of Minsk. The...
Diversity reception techniques can help to combat fast fading in urban areas, and this paper describes some predetection combining systems designed to be compatible with existing standard receivers. Quantitative results show that a worthwhile improvement in quality of reception can be Obtained with small numbers of antennas. There are advantages to be gained if, in future receiving systems, the diversity...
