摘要： A polarimetric transceiver front-end includes two receive paths configured to receive signals from an antenna, each receive path corresponding to a respective polarization. Each front-end includes a variable amplifier and a variable phase shifter; a first transmit path configured to send signals to the antenna, where the transmit path is connected to the variable phase shifter of one of the two receive paths and includes a variable amplifier; and a transmit/receive switch configured to select between the first transmit path and the two receive paths for signals, where the transmit/receive switch includes a quarter-wavelength transmission line that adds a high impedance to the transmit path when the transmit/receive switch is in a receiving state.

摘要： Wireless packet switches and enclosures include multiple port controllers, each in communication with a respective wireless transceiver located on an outer surface of a spherical shell. Each port controller is configured to analyze data streams to and from the respective wireless transceiver. Each wireless transceiver is configured to establish beamforming connections with a client device in a beamforming direction pointed away from the spherical shell. A cross-connect switch is in communication with all of the port controllers, configured to provide connections between respective port controllers. An arbiter is in communication with all of the port controllers and with the cross-connect switch and is configured to control the cross-connect switch, such that the cross-connect switch connects data streams of the port controllers in accordance with packet destination information and scheduling information from the port controllers.

摘要： RFID (radio frequency identification) systems are provided in which tag and interrogator devices implement a hybrid framework for signaling including an optical transmitter/receiver system and an RF transmitter/receiver system. For instance, an RFID tag device includes: optical receiver circuitry configured to receive an optical signal having an embedded clock signal from an interrogator device, and convert the optical signal into an electrical signal comprising the embedded clock signal; clock extraction circuitry configured to extract the embedded clock signal from the electrical signal, and output the extracted clock signal as a clock signal for controlling clocking functions of the tag device; voltage regulator circuitry configured to generate a regulated supply voltage from the electrical signal, wherein the regulated supply voltage is utilized as a bias voltage for components of the tag device; and data transmitter circuitry configured to wirelessly transmit tag data to the interrogator device.

摘要： Methods and systems for wireless packet switching include determining a schedule for transceivers in an enclosure. The schedule specifies which of the transceivers will act as a transmitter and which will act as a receiver. A beamforming direction for transmitting data from each transmitter to each corresponding receiver is determined. It is determined that an angle of the beamforming direction for at least one transmitter is lower than a minimum angle. Data is transmitted from a transmitter to the corresponding receiver by a wired connection, responsive to the determination that the angle of the beamforming direction is lower than a minimum angle.
