Abstract
Systems, methods, and computer-readable media are described herein which utilizes and controls an electromagnetic energy beam steering apparatus. The electromagnetic energy beam steering apparatus uses directional properties of a Luneburg lens to receive RF energy from one or more points of the Luneburg lens and re-transmits the RF energy from a different point of the Luneburg lens to focus the RF energy in a desired direction. The electromagnetic energy beam steering apparatus may take a form of a passive repeater, an active repeater, or a multipath active repeater.
Claims20
An electromagnetic energy beam steering apparatus comprising:
- a Luneburg lens;
- a first antenna and a second antenna, wherein the first antenna is located at a first focal point of the Luneburg lens, and wherein the second antenna is located at a second focal point of the Luneburg lens, wherein the first antenna and the second antenna are configured to receive signals from a wireless access point within a duct system;
- and
- a transmission line, wherein the transmission line receives a collected signal from the first antenna and transmits the collected signal to the second antenna.
An electromagnetic energy beam steering method comprising:
- receiving an input signal at a Luneburg lens, wherein the input signal comprises a communication signal transmitted using a wireless access technology;
- focusing and collecting the input signal received at the Luneburg lens onto a first antenna located at a first focal point of the Luneburg lens, wherein the input signal is focused and collected as a first collected signal;
- and
- transmitting the first collected signal through a transmission line system, wherein the transmission line system transmits the first collected signal from the first antenna and combines the first collected signal with a signal used to mitigate self-interference cancellation to create a first transmit signal which is then transmitted to a second antenna and transmitted through the Luneburg lens, wherein the second antenna is located at a second focal point of the Luneburg lens.
One or more computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method for operating on an electromagnetic energy beam steering apparatus, the method comprising:
- receiving at a first receive antenna a first multipath signal and receiving at a second receive antenna a second multipath signal, wherein the first receive antenna is located at a first focal point of a Luneburg lens, and wherein the second receive antenna is located at a second focal point of the Luneburg lens;
- combining at a transmission line system a first collected signal from the first receive antenna with a second collected signal from the second receive antenna to create a first combined signal;
- and
- receiving the first combined signal and transmitting the first combined signal through the Luneburg lens using a first transmit antenna.
