Abstract
An alternative method of distributing RF in buildings is proposed in which the heating and ventilation ducts are used as waveguides. Because of the relatively low waveguide loss, this method may lead to more efficient RF distribution than possible with radiation through walls or the use of leaky coax. Further, the use of existing infrastructure could lead to a lower-cost system. Initial experimental results are p ....etc

Definition

Wireless transmission of electromagnetic radiation (communication signals) has become a popular method of transmitting RF signals such as cordless, wireless and cellular telephone signals, paper signals, two way radio signals,video conferencing signals and LAN signals indoors.

Indoor wireless transmission has the advantage that building in which transmission is taking place does not have to be filled with wires or cables that are equipped to carry a multitude of signals. Wires and signals are costly to install and may require ....etc

ABSTRACT
The hottest technology in personal networking is wireless networking, which allows users to share a high-speed internet connection among multiple computers without being tethered to wires or wall jacks. Traditional indoor wireless uses a network of transmitters receiver and antennas for communication in the interior of a building. Such a placements is more a matter of trial & error and may many a times lead to ineffective communication. An easy solution to this problem using the already existing infra ....etc

Effect of HVAC System on Neighbouring Pipelines and
Communication Cables

A. Abu-Siada, M. Bahram
Curtin University of Technology, Australia

Abstract—
Sharing of common corridors between power lines, pipelines and telecommunication lines is becoming a familiar scene. High levels of voltages can be induced in services which run in parallel or in close vicinity of high voltage AC transmission lines, in particular during a fault on the transmission line. These hazardous voltages can af ....etc

AN EXACT SOLUTION FOR ONE-DIMENSIONAL ACOUSTIC FIELDS IN DUCTS WITH AN AXIAL TEMPERATURE GRADIENT
In this paper an approach is presented for obtaining exact analytical solutions for sound
propagation in ducts with an axial mean temperature gradient[ The one!dimensional wave
equation for ducts with an axial mean temperature gradient is derived[ The analysis neglects
the e}ects of mean ~ow\ and therefore the solutions obtained are valid only for mean Mach
numbers that are less than 9=0[ The derived wave equation is then transformed t ....etc
