Abstract: High bandwidth services provided in the core of the network may be extended to the network edge by utilizing one or more underground wireless communications links. The underground communications link may be formed by burying a broadcasting antenna in a first underground location and then burying another underground antenna at a geographic point where services are desired. By transmitting the signals underground, it is possible to reach a large number of remote sites without undertaking the expense associated with providing direct high-speed fiber optic, cable, or wireline connections to those sites. Additionally, since the transmission is underground, the wireless communications may be provided in a portion of the spectrum otherwise licensed for use aboveground. This reuse of spectrum in a different transmission medium results in a large increase in the amount of data that may be transmitted over the existing allocated wireless spectrum.
