摘要： Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.

摘要： Methods and apparatuses for point-to-point or point-to-multipoint transmission/communication of high bandwidth signals. High bandwidth signals may be efficiently transmitted by a radio device having a pair of reflectors separated by an isolation choke boundary. The two reflectors may be connected or formed of a single housing, and may be mounted to a wall, pole, etc. using a quick-connect. The devices may be configured to operate in any appropriate band (e.g., a 5GHz band, a 24 GHz band, etc.) and may be configured for accurate and easy alignment with one or more remote radio devices. Alignment may be assisted by displaying both local and remote transmission information during alignment.

摘要： Radio devices having separate transmission and reception reflectors for transmitting and receiving wireless signals that detect interference in a transmission channel and may be automatically or manually switch duplexing schemes when reflections, radar or other interference is detected. These devices typically include both a transmission antenna reflector and a receiving transmitter reflector, which may be connected or formed of a single housing, that are operatively coupled to radio circuitry for transmission and reception of wireless signals. Interference, and particularly reflected signals between the transmitter and receiver, are avoided by including a detector coupled to either (or both) reflectors that monitors the transmitting frequency channel; reflections and/or radar signals may be detected and may trigger switching (manual or automatic switching) to a different duplexing modes such as frequency-division duplexing (FDD), time-division duplexing (TDD), etc.

摘要： Devices and systems, and methods of using them, for point-to-point transmission/communication of high bandwidth signals. Radio devices and systems may include a pair of reflectors (e.g., parabolic reflectors) that are adjacent to each other and configured so that one of the reflectors is dedicated for sending/transmitting information, and the adjacent reflector is dedicated for receiving information. Both reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. In many variations the two reflectors are formed of a single housing, so that the parallel alignment is fixed, and reflectors cannot lose alignment. The device/systems may be configured to allow switching between duplexing modes. These devices/systems may be configured as wide bandwidth zero intermediate frequency radios including alignment modules for automatic alignment of in-phase and quadrature components of transmitted signals.

摘要： Radio apparatuses and methods for MIMO matrix phasing that may be used to toggle and/or weight the amount of MIMO processing based on the detected level of isolation between different polarizations of the system. Also described herein are apparatuses including auto-range and/or auto-scaling of a signal strength indicator to aid in precise alignment of the apparatus. Any of these apparatuses and methods may also include dynamic power boosting that adjusts the power (e.g., power amplifier) for an RF apparatus based on the data rate. These apparatuses may include a housing enclosing the radio device that includes a plurality of pin elements that may act as heat transfer pins and a ground pin for making a ground connection to the post or pole to which the devices is mounted.
