Monograph; The monograph describes the principles of construction, logical and physical structure of wireless information networks, including personal networks (SE 802.) 15, including Bluetooth standard), local wireless networks (IEEE 802. standards 11 and DECT), regional networks of IEEE 802. 16, cellular telephone and trunking networks, digital television and radio broadcasting systems, satellite systems and optical atmospheric communication channels. The theoretical bases of information transfer (theorems of Shannon, Kotelnikov and Nayquist), methods of coding and modulation in wireless networks are presented . New methods of performance assessment and design of local and regional wireless networks under the control of IEEE 802 protocols are described 11(16). The principles of construction and implementation of antenna systems for broadband communication. Describes the basics of circuitry and the principles of operation of smart antennas and MIMO technology, which is the basis of IEEE 802 . standards 11n and IEEE 802. 16-2004. Examples of regional networks implementation are given; a new technology for building broadband wireless networks using high-altitude platforms is described.
