Introduction to Bluetooth, 2nd Edition

This book provides a simplified description of Bluetooth technology, services, and profiles. You will find out how Bluetooth devices automatically locate nearby Bluetooth devices, authenticate them, discover their capabilities, and the processes that are used to setup connections with them. Discover how Bluetooth’s spread spectrum technology allows it to operate with other devices including wireless LAN, microwave ovens, cordless telephones, and wireless video cameras. You’ll discover how the Bluetooth specification now allows devices to adapt their frequency transmissions to avoid interfering with these devices. You will learn about the discovery (inquiry) phase and the connection (paging) process that devices use to find and connect to other devices. The modulation types and packet structures are explained along with how the use of multislot RF packets can dramatically increase the data throughput between devices. Learn how enhanced data rate (EDR) can increase the data transmission rate from 1 Mbps to 3 Mbps. The protocol layers are explained including the RF baseband (physical), link manager, L2CAP (transport), and upper session and application layers. You will learn about the many Bluetooth profiles that define the services and applications that Bluetooth can provide. Bluetooth security processes such as pairing (authentication), privacy (encryption), and the new simple pairing processes are described. Discover that Bluetooth has evolved and continues to evolve from basic 1 Mbps Piconet services to the proposed Bluetooth 480 Mbps UWB services.
