摘要： An information handling system includes a wireless local area network (WLAN) radio and a system embedded controller (EC). An antenna controller may determine an antenna type from a group consisting of a passive antenna and an active antenna, map a platform-unique subsystem identifier in accordance with the antenna type, configure a heartbeat message path to the system EC based on the antenna type, and control a WLAN radio transmit power level based on a heartbeat status.

摘要： A method and information handling system (IHS) for dynamic multiple antenna sensor and wireless power management for multiple radio types and multiple wireless configurations comprise enabling, by an antenna controller (AC), a proximity sensor (P-sensor) connected interrupt to be generated by a P-sensor; upon activation of the P-sensor connected interrupt, determining, at the AC, a reason for the P-sensor connected interrupt; when the reason is a steady-state detection event, calibrating, by the AC, the P-sensor; when the reason is a proximity detection event, storing, by the AC, a radio transmit power lookup table, the radio transmit power lookup table mapping a P-sensor channel, an antenna subsystem physical configuration value, and an IHS physical configuration usage mode value to a radio transmit power level value; and configuring, at a radio, the radio to operate at a radio transmit power level corresponding to the radio transmit power level value.

摘要： An information handling system includes a data radio connected to an antenna system, and a proximity sensor connected to a proximity sensor probe. An antenna controller (AC) may determine whether a capacitance measurement coarsely indicates a specific antenna configuration or a coarse fault; and configure, when the capacitance measurement indicates a coarse fault, a data radio to operate at a failsafe radio transmit power level; determine, when the capacitance measurement indicates the specific antenna configuration, whether a detail capacitance measured with respect to the antenna system indicates proper antenna configuration or an out-of-range value; configure, when the detail capacitance indicates proper antenna configuration, the data radio to operate normally; and configure, when the detail capacitance indicates an out-of-range value, the data radio to operated in a mode where a performance parameter of the data radio is particularly monitored.

摘要： An information handling system includes an antenna controller that may receive, from a platform sensor, platform sensor information as to a physical configuration usage mode, and receive, from a proximity sensor, information as to a part of a body of a user to an antenna. The antenna controller may also obtain a radio transmit power level value corresponding to the platform sensor information and to the proximity sensing information, send the radio transmit power level value to a radio via a serial interface, and reconfigure the antenna in response to the platform sensor information and the proximity sensing information. A radio may adjust a radio transmit power level to an adjusted radio transmit power level based on the radio transmit power level value.

摘要： According to one illustrative, non-limiting embodiment, an IHS may include computer-executable instructions for receiving first and second signal quality measurements from first and second antennas disposed at a first and second locations, respectively, in a housing of an IHS in which the first location is distally separated from the second location. The instructions then select one of the first or second antennas according to the first or second signal quality measurement, and establish a first wireless communication link with a remote device using the selected first or second antennas.
