Architecture MAC Sublayer Physical Layer Topics discussed in this section: 14. A BSS without an AP is called an ad hoc network; a BSS with an AP is called an infrastructure network. Note 14. Figure Basic service sets (BSSs) 14. Figure Extended service sets (ESSs) 14. Figure MAC layers in IEEE standard 14. Figure CSMA/CA flowchart 14. Figure CSMA/CA and NAV 14. Figure Example of repetition interval 14. Figure Frame format 14. Table Subfields in FC field 14. Figure Control frames 14. Table Values of subfields in control frames 14. Table Addresses 14. Figure Addressing mechanisms 14. Figure Hidden station problem 14. The CTS frame in CSMA/CA handshake can prevent collision from a hidden station. Note 14. Figure Use of handshaking to prevent hidden station problem 14. Figure Exposed station problem 14. Figure Use of handshaking in exposed station problem 14. Table Physical layers 14. Figure Industrial, scientific, and medical (ISM) band 14. Figure Physical layer of IEEE FHSS 14. Figure Physical layer of IEEE DSSS 14. Figure Physical layer of IEEE infrared 14. Figure Physical layer of IEEE 14. 14-2 BLUETOOTH Bluetooth is a wireless LAN technology designed to connect devices of different functions such as telephones, notebooks, computers, cameras, printers, coffee makers, and so on. A Bluetooth LAN is an ad hoc network, which means that the network is formed spontaneously. Architecture Bluetooth Layers Baseband Layer L2CAP Topics discussed in this section: 14. Figure Piconet 14. Figure Scatternet 14. Figure Bluetooth layers 14. Figure Single-secondary communication 14. Figure Multiple-secondary communication 14. Figure Frame format types 14. Figure L2CAP data packet format 14.
