摘要： Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

摘要： A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.

摘要： An antenna for providing light is disclosed. The antenna may comprise a substrate having at least two domains and a light source which is connected to two domains. The light source may emit light when a direct current flows from one domain to another domain. A radio frequency (RF) current flows through the domains for generation of radio waves. A capacitor is provided between adjacent domains to provide a path for the RF current to bypass the light source. The substrate is enabled to absorb the heat dissipated by the light source. The substrate is coated with a reflective material to reflect impinging light rays.

摘要： A metasurface device includes an antenna element formed on the front surface of a substrate, the antenna element comprising a two-dimensional array of electrically conductive patches spaced from one another and having dimensions smaller than the operating wavelength of an emission and/or reception device, the antenna element being able to radiate in a direction having a component perpendicular to the front surface of the substrate when the ground structure has a ground plane function, the substrate comprising a layer, called a connection layer, made of photoconductive semiconductor material, in direct physical contact with the conductive patches, the semiconductor material being insulating when it is not illuminated and able to be conductive when it is illuminated at a reconfiguration wavelength.
