A transmission medium is something that can mediate the propagation of signals for the purposes of telecommunication. Signals are typically imposed on a wave of some kind suitable for the chosen medium. For example, data can modulate sound and a transmission medium for sounds may be air, but solids and liquids may also act as the transmission medium. Vacuum or air constitutes a good transmission medium for electromagnetic waves such as light and radio waves. While material substance is not required for electromagnetic waves to propagate, such waves are usually affected by the transmission media they pass through, for instance by absorption or by reflection or refraction at the interfaces between media. Technical devices can therefore be employed to transmit or guide waves. Thus, an optical fiber or a copper cable are used as transmission media.

Illumination device for simulating neon or similar lighting using phosphorescent dye
An illumination device simulates neon lighting using a light source for emitting light of a predetermined first hue and a light-transmitting medium having a predetermined density of phosphorescent dye positioned adjacent to the light source. The phosphorescent dye will absorb light emitted by the light source and emit light of a second hue. An observer of the device perceives light that is of a hue that is different from the predetermined first hue. A means for varying the intensity of the light emitted by the light source creates color changing effects in the illumination device. Light-emitting diodes (LEDs) are a suitable light source. A waveguide having both optical waveguide and light scattering properties is used to diffuse the combined light and simulate the uniform appearance of a neon tube. Alternatively, the waveguide itself can be doped with phosphorescent dye to emit light having the perceived hue.

At least one constituent node in such automatically configurable transient pathways is mobile, for example, information (source) server, intervening router node(s), gateway server and / or client device. Additionally, Autoband's ad hoc communications pathways may seamlessly and dynamically integrate (i.e., “graft”) into standard fixed node networks such as terrestrial networks, other wireless networks or combinations thereof. These communications may consist of point-to-point or multicast links. An economic market-based approach further assures allocation of available network resources (i.e., bandwidth and processing) needed to achieve the most optimally resource efficient communications pathway configurations for the totality of communications. Consequently, optimal network resource allocation and efficiency at a system-wide level is continuously achieved.

A closed loop feedback system is employed in a receiver to automatically compensate the communication signal from twisted pair cables for AC and DC losses. This is accomplished through the use of a reference pulse signal which is sent along with other digital information. At the receiver, the reference pulse signal is restored to its proper level through a Pulse Width Modulation (PWM)-controlled variable compensation amplifier circuit. The received reference signal is compared to a known reference value and the duty cycle of the PWM circuit is adjusted until the proper level reference signal is achieved. Thereafter, the digital signal is extracted. OFDM (Orthogonal Frequency Division Multiplexing) with pilot tones are used to maximize payload while minimizing crosstalk effects. The pilot tones locate the OFDM symbols in time while supplying compensation information concerning the transmission medium.
