Local Area Networks Gerd Keiser

Chapter Eight of Gerd Keiser's work delves into Wireless LANs, focusing on the IEEE 802.11 protocol's role within the ISO model. It features clear illustrations of the PLCP frame formation from LLC PDUs, wireless device communication with LAN access points, and various network structures like BSS and ESS. Additionally, it explores the MAC architecture, access methods for CSMA/CA, and frame formats. The chapter also compares ISM spectral bands, examines spread spectrum methods, and discusses Bluetooth networks, providing a comprehensive overview of wireless networking principles.
