The present invention relates to a method of performing a cell selection by a User Equipment in a wireless communication system. A first set of trenches is formed in the silicon substrate, leaving laterally-isolated rows of silicon between the trenches. Automated comparisons of current inspection data against normative or historical data may be performed, so in depth review of the current inspection is triggered only when the difference between current inspection data and the normative or historical data exceeds a predetermined threshold. A light dispenser at a distal end of the laser fiber deliver laser light through the balloon. The method and apparatus is generalized to the multiple channel case and exploits the cross-power spectra among all of the channels. Antenna arrays of one or more coaxial cable units, wherein the inner conductors of each unit are electrically connected and the outer conductors are electrically connected, and the units are inductively coupled, may be provided.
