An over-the-air (OTA) test and/or measurement system for testing a device under test (DUT) is described. The DUT is configured to communicate with satellites. The OTA testing system includes at least one radio frequency (RF) antenna, at least one antenna positioner, and a control circuit. The RF antenna is attached to the antenna positioner. The RF antenna is configured to transmit and/or receive RF signals. The antenna positioner is configured to adapt a position of the RF antenna. The control circuit is configured to perform a satellite emulation. Performing the satellite emulation includes at least one of controlling the RF antenna to emulate a transmission characteristic of at least one satellite, controlling the RF antenna to emulate a reception characteristic of the satellite, controlling the antenna positioner to emulate a relative position between the DUT and the satellite, or controlling the antenna positioner to emulate a trajectory of the satellite.

Provided is a measurement device that makes a screen for setting parameters easy to see, makes it possible to easily find a parameter desired to be set, and can suppress parameter setting errors. A measurement device includes a display unit 15 that displays an image and a control unit 16 that switches a setting screen for a Capability Element parameter between a setting screen for SISO communication and a setting screen for MIMO communication and displays the setting screen on the display unit 15 when communication conforming to an IEEE 802.11be standard is measured.

An apparatus (10) comprising means for: enabling testing of at least one user equipment (110, 12) over a plurality of radio frames by: determining (202), for at least one candidate position in a current radio frame, if one or more signals are to be transmitted to the at least one user equipment, based, at least in part, on one or more probabilities associated with the at least one candidate position in the current radio frame; if it is determined, for at least one candidate position in the current radio frame, that one or more signals are to be transmitted to the at least one user equipment, transmitting (204) one or more signals to the at least one user equipment using the at least one candidate position in the current radio frame; if it is determined, for at least one candidate position in the current radio frame, that one or more signals are not be transmitted to the at least one user equipment, determining (206) if a maximum number of transmission failures has occurred, wherein a transmission failure is determined to have occurred when it is determined that no signals are to be transmitted in a current radio frame; and if it is determined that a maximum number of transmission failures has occurred, transmitting (208) one or more signals to the at least one user equipment using at least one candidate position in the current radio frame.

Systems and methods for Wi-Fi sensing are provided. Wi-Fi sensing methods may be carried out by a networking device configured to operate as an access point (AP) within a mesh network. The AP may be configured to identify a reciprocal AP with which the AP has a reciprocal wireless link. The AP may be configured to determine a first AP role determination metric associated with the AP and receive a second AP role determination metric associated with the reciprocal AP. The AP may be configured to compare the first AP role determination metric to the second AP role determination metric to allocate a first sensing role to the AP based on the comparing and allocate a second sensing role to the reciprocal AP based on the comparing.
