Granatstein Boca Raton Auerbach Publications 2008 Including coverage of cellular telephones, satellite television beaming, satellite data transmission, satellite telephones, and wireless computer networks, Granatstein (former director of the Institute for Plasma Research at the U. of Maryland) presents descriptions of the salient features of modern wireless communication systems together with analysis of the devices and their physical mechanisms. He begins with a review of Maxwell's equation and discussion of the operation of antennas and antenna arrays in sufficient detail to allow for design calculations. He then reviews principles of probability theory relevant to the calculation of statistical variation in path loss and also covers the physics of geostationary earth orbiting satellites and low earth orbiting satellites important to first order designs of satellite communication systems Wireless communication systems.,Vô tuyến điện Trọng Hải Trung tâm Học liệu Trường Đại học Cần Thơ
