The main goal of the book is to develop models for designing WLAN, used in transport networks with mobile objects. At that quality indicators of functioning of networks should be maximally close to the actual data. Due to the fact that the interaction of local wireless network takes place within the coverage area, its Access Point occurs with a limited number of clients - closed cyclic models are used for transport vehicles to simulate such systems. In this book, the number of mobile objects determined depending on the distance from the base station and identification of system parameters of data transmission, based on this the problem of determining of the actual speed of data transmission from the moving objects is solved, located within the coverage area of the base station of wireless network.
