A wireless communication network with a hierarchical star structure is considered as a queuing system. A topological scheme is proposed that contains a combination of several single-channel and one multi-channel queuing systems. Oriented graphs of queuing systems are composed. The formulas of probabilistic indicators of the network functioning efficiency are obtained. The estimation of the average...
The paper is devoted to the problem of defining the contribution of the diffraction rays to the electromagnetic field structure for indoor radio systems. The proposed analytical and computational approaches of accelerating the diffraction coefficients calculation allow performing an approximate calculation of the diffraction field with small computational cost in the problems of multipath propagation...
The problem of evaluating reliability of telecommunication systems in general, and their components is considered. The method of forecasting the reliability of a telecommunications system designed according to the results of stress testing is proposed. The essence of the proposed method is to use the emissions of a random process as a diagnostic parameter that displays the trajectory of a monitored...
Planning and maintenance of WLAN includes continuous monitoring of the signal level throughout the volume of the coverage area. Simulation methods of frequency planning and territorial planning based on ray tracing of signals are widely used for this purpose. The main limitation of these methods is the smooth approximation of reflecting surfaces in a room. A method of accounting irregularities of...
