This monograph explores the principles of constructing and the logical and physical structures of wireless data transmission networks on urban and regional scales. It delves into IEEE 802.11 wireless networks, including mesh networks, and describes the architecture and organizational principles of WiMAX networks—presented for the first time in domestic literature. The book provides a detailed account of the IEEE 802.16 radio access technology, including mobile networks (IEEE 802.16e). It also covers cellular networks based on 3G and LTE standards (again, a first in local literature), as well as technologies for broadband digital television and radio broadcasting (DVB and DAB). The principles of MIMO technology are outlined, and examples of regional WiMAX network implementations are provided. The theoretical foundations of information transmission are discussed, including Shannon's, Kotelnikov's, and Nyquist's theorems, as well as methods of encoding and modulation in wireless networks. Overall, this monograph serves as a unique reference guide to the current technologies of broadband wireless access, addressing topics from network architecture to the hardware implementation of devices and principles of equipment certification. By combining essential theoretical foundations of wireless telecommunications with descriptions of specific standards, circuit design principles for supporting devices, and examples of actual wireless network implementations, this book is invaluable to a wide audience. It is particularly beneficial for professionals involved in the development of broadband wireless networks, telecommunications equipment developers, IT department heads, graduate students, and technical university students.
