A method includes receiving information relating to interference between a relay node associated with a first base station and at least one other relay node associated with a second base station. The method includes providing a semiconductor structure which includes a semiconductor layer, a gate dielectric layer on the semiconductor layer, and a gate electrode region on the gate dielectric layer. The first LPG converts light, over a broad wavelength range, being transmitted in the fundamental, or LP01, mode of the optical fiber transmission line into light in a higher order mode of the optical fiber. Each of the legs may include a lower portion, a body portion and an upper portion that is preferably selectively connected to the table top. The first communication including the graphic is transmitted over the communication network.
