Workers in hazardous environments such as mining are constantly exposed to the health and safety hazards of dynamic and unpredictable conditions. One approach to enable them to manage these hazards is to provide them with situational awareness: real-time data (environmental, physiological, and physical location data) obtained from wireless, wearable, smart sensor technologies deployed at the work area. The scope of this approach is limited to managing the hazards of the immediate work area for prevention purposes; it does not include technologies needed after a disaster. Three critical technologies emerge and converge to support this technical approach: smart-wearable sensors, wireless sensor networks, and low-power embedded computing. The major focus of this report is on smart sensors and wireless sensor networks. Wireless networks form the infrastructure to support the realization of situational awareness; therefore, there is a significant focus on wireless networks. Lastly, the “Fut… More >>

A Technology Review of Smart Sensors with Wireless Networks for Applications in Hazardous Work Environments

Wireless systems for mobile communication is one of the most rapidly expanding fields in digital telecommunications. Such hot topics as wireless Internet, mobile access to multimedia services and wireless convergence systems are likely to affect the whole of the information society and will pose intellectual challenges to researchers in the foreseeable future. Transmission techniques like WCDMA, user-oriented protocols like WAP and communication structures like LEO are just a few tools that seem to usher in the era of unlimited resource availability. Personal Wireless Communications addresses these issues, with 17 regular papers and 4 invited papers by leading researchers in the area of wireless communications. The volume comprises the proceedings of the Working Conference on Personal Wireless Communications (PWC’2000), which was sponsored by the International Federation for Information Processing (IFIP) and held in Gdansk, Poland in September 2000. The contributions cover a wide rang… More >>

Mobile, Wireless, and Sensor Networks: Technology, Applications, and Future Directions

The expansion and popularity of the Internet, along with the addition of wireless data functionality to wireless networks, has also contributed greatly to the growth of the wireless industry. In fact, the anticipated consumer demand for high bandwidth wireless data is commonly seen as the driving force behind current network upgrades and expansions. The number and types of companies aggressively investing in wireless technologies illustrate the importance of wireless data. Non-traditional telecommunications companies such as Cisco Systems, Intel, Microsoft, 3Com, and other professional services companies, are investing heavily in wireless product development and many have formed partnerships with wireless infrastructure manufacturers to help deliver wireless data services seamlessly to consumers. Written by a respected author this self-contained overview of wireless date technologies will provide a highly sought after technical reference to all those working within the main areas of W… More >>

Wireless Data Technologies

Multi-carrier technologies have emerged as important instruments in telecommunications. OFDM is in the forefront, with its adoption by the IEEE 802.11 standards committee and the European HYPERLAN standards group. Following OFDM, MC-CDMA is also demonstrating considerable promise when compared to competing technologies. According to the authors, these technologies are just the beginning in the coming multi-carrier revolution. In Multi-Carrier Technologies for Wireless Communication, the authors explain how a common multi-carrier platform is being designed for DS-CDMA, TDMA, OFDM and MC-CDMA systems. Findings are presented which show how this multi-carrier platform enhances network capacity and probability of error performance.Specific results include (1) innovation in multi-carrier technologies that are enabling them to become an integral part of TDMA and DS-CDMA systems; and (2) the design of multi-carrier systems to overcome PAPR problems (in, e.g., OFDM). Multi-Car… More >>

Multi-Carrier Technologies for Wireless Communication

The fundamentals of microwave and wireless communications technology are critical to the telecommunications and data acquisitions fields. Because many of the new developments involve commonly available equipment such as cellular telephones and satellite dishes, technicians as well as engineers must learn the basics of the technology.

Microwave & Wireless Communications Technology offers a practical, device-based approach to the study of microwave and wireless communications. Student objectives, numerous questions and problems, and end-of-chapter summaries reinforce the theory in each chapter. Answers to odd-numbered questions are provided in the back of the book. Math is kept to the lowest practical level, and the last section of each chapter is a collection of the key equations laid out for the student. A Windows diskette with supplementary instructor material is available on request with adoption.
