PowerCorridor^tm consists of two main patented innovations that together form Corridor's core technology: E-Line^tm and Virtual Physical Layer (VPL). Together, VPL and E-Line^tm provide very efficient, linear and broadband transport of information-carrying spectrum anywhere in the 100MHz - 10Ghz-range. The system utilizes off-the-shelf and commodity RF chipsets to provide extremely low-cost solutions for high-performance information delivery across overhead powerlines.


E-Line^tm
E-line^tm is a newly discovered and patented electro-magnetic transmission technique that can operate on a single conductor of an existing overhead power line. Information-carrying energy is coupled on and off of the conductor by identical launch devices on each end of the conductor. The energy, which may extend from VHF through the microwave portions of the spectrum, is launched as a radially symmetric planar wave around the conductor. This mode exhibits several important characteristics including (a) extremely low-loss over distance (b) fast propagation, and (c) low radiation. Its combination of extremely low transmission losses and broadband characteristics is much better than either coaxial cable or DSL, and second only to optical fiber.



E-Line^tm/VPL allows transport of spectrum across long distances of many miles. Combined with the normal clearances maintained for aerial medium and high-voltage power lines, and Corridor System's specially developed and patented launching devices, E-line^tm provides a very high-performance and cost-efficient transport across power lines for information-carrying RF signals, be they cellular antenna signals, WiFi, encoded Ethernet, or TDM (T1, T3, etc). This provides mobile carriers a convenient and strategic migration from 2G/3G to include other fixed-wireless services.

VPL
Virtual Physical Layer (VPL) is an alternative segmentation/modularization of the PHY networking layers so that (a) multiple physical transmission media may be used simultaneously, and (b) the coupling to a physical medium is separated from the process of encoding information. VPL allows more efficient information delivery, higher information capacities, and significant flexibility and cost advantages in implementation of physical-layer networks by allowing use of off-the-shelf and commodity RF chipsets such as WiFi, and UWB.
