摘要

Bluetooth devices operate at 2.4 GHz in the globally available, license-free ISM band. This band is reserved for general use by industrial, scientific, and medical (ISM) applications, which obey a basic set of power and spectral emission. The ISM band is shared by numerous wireless devices, which makes it relatively noisy.; Bluetooth wireless technology uses Frequency Hopping Spread Spectrum (FHSS) to avoid interference from other wireless devices operating in the ISM band.; This report presents a Bluetooth Frequency Hopping model simulated using Optimum Network Performance (OPNET) simulation software. The model demonstrates how a Master communicates with seven Slaves in a piconet while frequency hopping on a fixed hopping sequence.; Eight Bluetooth devices are modeled; one is a Master device and seven are Slave devices. These eight devices form a Personal Area Network (PAN) which is called the piconet. The Master controls the communication in the piconet. Only that Slave is allowed to transmit which is addressed by the Master in the preceding channel.; For the reliable communication, every packet transmitted by the Master to a Slave is acknowledged. A Slave may request for the retransmission using Automatic Repeat Request (ARQN).; Active member address is a 3-bit address that is used by the Master to address each Slave in the piconet. The use of this address is also demonstrated in this model.
