System and method for fine-tuning electromagnetic beams. One embodiment includes an array of electromagnetic radiators and beam-narrowing configuration. The array of electromagnetic radiators together generates an electromagnetic beam toward a configurable direction. The beam-narrowing configuration narrows the electromagnetic beam and consequently fine-tune the configurable direction. Optionally, the array of electromagnetic radiators is a phased-array that achieves the configurable direction electronically. Additionally or alternatively, the array of electromagnetic radiators is a millimeter-wave array, and the electromagnetic beam is a millimeter-wave beam.

Various embodiments of a millimeter-wave wireless point-to-point or point-to-multipoint communication system which enables determining preferred directions of transmissions, and transmitting in such preferred directions without routing radio-frequency signals. The system comprises a millimeter-wave focusing element, multiple millimeter-wave antennas, and multiple radio-frequency-integrated circuits ('RFICs'). In various embodiments, preferred directions are determined, and millimeter-wave beams are transmitted in the preferred directions.

Systems and methods for beam direction by switching sources

Various embodiments of a communication system operative to form, direct, and narrow communication beams using an array of electromagnetic radiators and a beam-narrowing architecture. A beam-width of an electromagnetic beam is narrowed, thereby increasing the concentration of electromagnetic energy in the beam and achieving a significant antenna gain. In various embodiments, the direction of an electromagnetic beam may be altered to improve communication between a transmitter and a receiver. In various embodiments, the system is a millimeter-wave system with a millimeter-wave array and millimeter-wave beams.

Millimeter-wave system with beam direction by switching sources

A clock extractor extracts clock frequency f, from a wired data connection feeding the transmitter with data clocked at the clock frequency f. A clock error estimator estimates clock frequency error between the clock frequency fand a clock frequency fderived from a local clock of the transmitter. Clock adder adds the clock frequency error to the clock frequency f, resulting in a synthesized clock frequency f. A modulator uses the synthesized clock frequency f, to modulate a data stream into a modulated signal.

Distributing clock associated with a wired data connection over wireless interfaces using frequency correction at the transmitter side

A clock extractor extracts clock frequency f, from a wired data connection. A clock error estimator estimates a first clock frequency error between clock frequency fand a clock frequency fassociated with a local clock of the transmitter. A transmitter sends the first clock frequency error, as a message to a receiver. The transmitter uses a wireless transmitter interface, including a modulator and transmitter radio. The wireless transmitter interface is clocked at clock frequency f. The transmitter sends data to the receiver. A wireless receiver interface includes a de-modulator and receiver radio. The wireless receiver interface reconstructs clock frequency f. A clock adder adds the reconstructing clock frequency fto the first clock frequency error, resulting in a synthesized clock frequency f. The receiver clocks a second wired data connection, using the synthesized clock frequency f
