    Beskrivning

    IEEE 802.11ba Discover the latest developments in IEEE 802.11ba and Wake-up Radios In IEEE 802.11ba: Ultra-Low Power Wake-up Radio Standard, expert engineers Drs. Steve Shellhammer, Alfred Asterjadhi, and Yanjun Sun deliver a detailed discussion of the IEEE 802.11ba standard. The book begins by explaining the concept of a wake-up radio (WUR) and how it fits into the overall 802.11 standard, as well as how a WUR saves power and extends battery life. The authors go on to describe the medium access control (MAC) layer in detail and then talk about the various protocols used to negotiate WUR operation, its uses for different functionalities (like wake up of the main radio, discovery, synchronization, and security). The book offers a detailed description of the physical (PHY) layer packet construction and the rationale for the design, as well as the various design aspects of the medium access control layer. It also includes: A thorough introduction to the motivations driving the development of the WUR in 802.11Practical overviews of IEEE 802.11, including the basic concepts of 802.11 (the PHY and MAC) and background material on current low power modesComprehensive discussions of the physical layer and PHY layer performance, including the generic receiver, the PPDU, Transmit Diversity, and the FDMA modeIn-depth examinations of the medium access layer and its frame designsPerfect for professional wireless engineers, IEEE 802.11ba: Ultra-Low Power Wake-up Radio Standard will also earn a place in the libraries of academics and students researching and studying in fields involving wireless communications.
