This page will investigate in detail how this would work under all conceivable situations, and try to discover any problems. The general feeling at the present is that a cellular phone system would perhaps function better. But if a waveguide system could be made to function reliably, it would have some considerable advantages. How the waveguides would be used 1. Some Waveguide Theory Waveguides are used for transferring signals where the wavelengths involved are so short that they are of the same size as the electronic circuits.
Electronic currents create magnetic fields that radiate away from the currents.
At low frequencies, this energy is mainly re-absorbed by the current, as the direction of current changes. As the frequency is increased, however, proportionately more of the energy is lost to this magnetic field, which in turn creates an electric field. At sufficiently high frequencies, most of the energy at any given moment is stored in this field. At this point, it makes more sence to transmit this electro-magnetic field, than the current itself. Waveguides can have a circular or a rectangular cross-section.
