Abstract:
System and methods to adapt a network of millimeter-wave communication nodes to a changing condition. The system detects a changing condition and concludes that the network needs to be adjusted. As a result, the system transitions, substantially instantaneously, between a current network topology to a new network topology, by instructing each of several millimeter- wave communication nodes to electronically steer the respective millimeter-wave beam away from current destination node and toward another destination node. The end result is that several of the beams change direction during a short period of time, thereby transitioning to the new network topology without impacting ongoing communication. In some embodiments, the transition between network topologies is done multiple times in a systematic fashion so as to generally find an optimal network topology and not as a response to a changing condition. In some embodiments, the transition between network topologies is a normal ongoing mode of operation.

Various embodiments of a millimeter-wave system operative to enhance propagation of millimeter-waves inside a laminate waveguide structure, in which electrical energy has leaked outside the laminated waveguide structure. The system comprises a laminate waveguide structure inside a printed circuit board, and an electrically conductive fence also inside the printed circuit board but outside the laminate waveguide structure. In various embodiments, the electrical energy of millimeter-waves leaks outside the laminate waveguide structure and is reflected by the electrically conducive fence back into the laminate waveguide structure.

Various embodiments have holes extending through lamina in the PCB, thereby improving radiation propagation. Various embodiments have conductive cages created by multiple through-holes extending through lamina in the PCB, thereby increasing radiation propagation. The manufacture of such systems is easier and less expensive than the manufacture of current systems.
Abstract:
A method of automatic alignment of two directional beams having a known path attenuation, and an antenna gain pattern, for mutual transmission, comprises: determining a beam width between two angles of minimal detectable connection on either side of a beam maximum; then mapping points onto a scan field in a regular pattern, the pattern based on the beam width, such that a beam with the determined beam width is detected once if the beam is in the scan field at all; scanning the first antenna over the mapped scan points; and for each point allowing the second antenna to scan over all of its own set of mapped scan points, thereby providing a coarse alignment of the two antennas to achieve at least a minimal mutual connection. The coarse alignment may be followed by a fine alignment to maximize the signal.
Abstract:
System and methods to facilitate simultaneous millimeter-wave transmissions over a common frequency. A plurality of millimeter-wave communication nodes are arranged or selected so as to form a spatially non-straight graph. Millimeter-wave beams are electronically steered from at least some millimeter-wave communication nodes toward adjacent millimeter-wave communication nodes, in which the millimeter-wave beams are narrow enough to miss non-adjacent nodes but still reach the adjacent nodes; a condition that is directly facilitated by the spatial properties of the graph, and thereby allowing all of the beams in the spatially non-straight graph to share the common frequency without causing inter-node interferences.
Abstract:
System und Verfahren zum Anpassen eines Netzwerks von Millimeterwellen-Kommunikationsknoten an sich ändernde Bedingungen. Das System erkennt einen sich ändernden Zustand und schließt daraus, dass das Netzwerk angepasst werden muss. Im Ergebnis wechselt das System im Wesentlichen augenblicklich zwischen einer aktuellen Netztopologie zu einer neuen Netztopologie, indem jeder von mehreren Millimeterwellen-Kommunikationsknoten angewiesen wird, den jeweiligen Millimeterwellenstrahl elektronisch von dem aktuellen Zielknoten zu einem anderen Ziel hin zu lenken Knoten. Das Endergebnis ist, dass mehrere Strahlen innerhalb einer kurzen Zeit die Richtung wechseln und so zur neuen Netztopologie wechseln, ohne die laufende Kommunikation zu beeinträchtigen. In einigen Ausführungsformen wird der Übergang zwischen den Netzwerktopologien auf systematische Weise mehrmals durchgeführt, um im Allgemeinen eine optimale Netzwerktopologie zu finden und nicht als Antwort auf eine sich ändernde Bedingung. In einigen Ausführungsformen ist der Übergang zwischen den Netzwerktopologien ein normaler fortlaufender Betriebsmodus.
