As cellular communications evolves towards 3G and beyond, the software radio approach will become central in coping with the multitude of problems that the coexistence of multiple standards poses. A concrete case study of the application of the software radio approach in multi-standard transceiver design is described. This case study consists of a multi mode GSM/EDGE/UMTS/Bluetooth modulation/demodulation testbed. The proposed approach extends the action of DSP processors beyond simple or low rate baseband digital processing transceiver functions, which is current practice, to high rate baseband functions and even a part of the IF processing (e.g., frequency conversion). Implementation, performance and system quality aspects are discussed

Bluetooth and IEEE 802.11 (Wi-Fi) are two communication protocol standards that define a physical layer and a MAC layer for wireless communications within a short range (from a few meters up to 100 m) with low power consumption (from less than 1 mW up to 100 mW). Bluetooth is oriented to connecting close devices, serving as a substitute for cables, while Wi-Fi is oriented toward computer-to-computer connections, as an extension of or substitution for cabled LANs. In this article we offer an overview of these popular wireless communication standards, comparing their main features and behaviors in terms of various metrics, including capacity, network topology, security, quality of service support, and power consumption.

Bluetooth is a method for data communication that uses short-range radio links to replace cables between computers and their connected units. Industry-wide Bluetooth promises very substantial benefits for wireless network operators, end workers, and content developers of exciting new applications. This article delves into the implementation and architecture of Bluetooth. It also describes the functional overview and applications of Bluetooth, and deals with the development of a model for recording, printing, monitoring, and controlling of eight process variables at the same time, using a distributed control system. We explain industrial automation via Bluetooth using IISS. Industrial automation is one of the major applications of Bluetooth technology. Industrial automation, in terms of controlling or monitoring a factory, office, or industrial process, means to install machines that can do the work instead of human workers. Industrial plants consists of many devices interconnected in different ways ranging from simple data collection units (I/O) to more intelligent devices such as sensors, one-loop controllers, or programmable controllers, and a supervisory system used as a human-machine interface (HMI) for data logging and supervisory control. An IISS is a controlling device that monitors the devices in a company. It basically communicates via the interface card in the PC; the hardware is connected parallel across the device, and it is interfaced with the PC via a transceiver. The device can be accessed both manually via the switches and remotely via the PC. A simulation of connecting a PC with the machines in a company was executed. Also, we wrote a software program using C language; we will show how the remote monitoring takes place between the control room and the PC. These details in the article establish the growing need for Bluetooth technology

An overview of Bluetooth Wireless Technology/sup TM/ and some competing LAN standards

Bluetooth Wireless Technology/sup TM/ is a low-cost cable-replacement method for connecting computer-based devices in home and small office environments. Intended as a universal, global standard, it has not developed as fast or as pervasively as initially hoped, but is having a major impact. This tutorial overview presents basic concepts of the Bluetooth standard, the transmission and modulation environments of the unlicensed ISM frequency bands, spread-spectrum communications options, link protocols, data rates, formation of 'piconets' and security features. A review of other standards for wireless LANs is included, with some indications of implementation methods for Bluetooth Wireless Technology.
