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.

Claims

1. A method of providing communications services, comprising:

interconnecting a data link from a high bandwidth network to a base unit; and

transmitting subterranean wireless signals from the base unit to a second unit.

2. The method of claim 1, wherein the subterranean wireless signals are first transmitted over the data link from the high bandwidth network to the base unit, and are then transmitted from the base unit to the second unit.

3. The method of claim 2, wherein the subterranean wireless signals are in a frequency range between 1 and 4 gigahertz.

4. The method of claim 2, wherein the high bandwidth network forms a part of the Internet.

5. The method of claim 2, wherein the data link is a high bandwidth data link.

6. The method of claim 1, wherein transmitting subterranean wireless signals employs at least one subterranean directional antenna.

7. The method of claim 1, wherein the second unit is an end user, and wherein the method further comprises the steps of:

receiving, by the end user, the subterranean wireless signals via an underground antenna; and

transmitting, by the end user, subterranean signals from the end user to the base unit.

8. The method of claim 1, wherein the second unit is a pico cell network device configured to emit atmospheric wireless network signals.

9. The method of claim 1, wherein the second unit is a repeater base unit.

10. An apparatus for extending a high bandwidth communications network, comprising:

a base unit configured to receive high bandwidth communications signals from the high bandwidth communications network; and

a subterranean antenna connected to said base unit and configured to broadcast subterranean wireless signals.

11. The apparatus of claim 10, wherein the subterranean wireless signals are first transmitted over a data link from the high bandwidth network to the base unit, and are then transmitted from the base unit to the second unit.

12. The apparatus of claim 11, wherein the subterranean wireless signals are in a frequency range between 1 and 4 gigahertz.

13. The apparatus of claim 11, wherein the high bandwidth network forms a part of the Internet.

14. The apparatus of claim 10, wherein the subterranean antenna comprises a first subterranean directional antenna and a second subterranean directional antenna.

15. The apparatus of claim 10, wherein the first subterranean directional antenna is configured to transmit subterranean wireless signals at a first depth, and wherein the second subterranean directional antenna is configured to transmit subterranean wireless signals at a second depth.

16. A network, comprising:

a base unit configured to receive signals from a high bandwidth communications link and to transmit said high frequency high bandwidth signals under ground as high frequency high bandwidth underground data signals; and

a plurality of remote units, each said remote unit having the ability to receive the high frequency high bandwidth underground data signals.

17. The network of claim 16, further comprising:

a repeater unit configured to intercept the high frequency high bandwidth underground data signals, amplify the high frequency high bandwidth underground data signals, and transmit the amplified high frequency high bandwidth underground data signals underground as amplified high frequency high bandwidth underground data signals.

18. The network of claim 16, further comprising:

a pico cell unit configured to intercept the high frequency high bandwidth underground data signals, amplify the high frequency high bandwidth underground data signals, and transmit the amplified high frequency high bandwidth underground data signals aboveground as high frequency high bandwidth atmospheric data signals.
