摘要： A server information handling system baseboard management controller (BMC) includes an NFC transceiver that communicates NFC signals through an NFC antenna structure. The BMC selectively configures the NFC antenna structure to isolate portions of conductive material for use as an antenna in non-NFC communications, such as wireless local area network communications (WLAN) at 2.4 or 5 GHz or wireless personal area network (WPAN) communications at 2.4 or 60 GHz. In one embodiment, WLAN and WPAN communications are encrypted with a key provided through NFC or other types of wireless communication, such as visible, infrared or ultraviolet light signals.

摘要： A portable information handling system multi-purposes a near field communication (NFC) antenna to detect object proximity of objects by interfacing a capacitive proximity processor with the NFC antenna and isolating the capacitive effects at the NFC antenna with a capacitive matching circuit disposed between the NFC antenna and an NFC transceiver. Comparison of the objects detected proximate the NFC antenna and proximate a conductive antenna provides a distinction of different types of objects, such as human forms versus a desktop.

摘要： Systems and methods are disclosed for dynamic switching of antennas. A portable information handling system includes a housing having a plurality of edges, a first antenna and a second antenna. The first antenna is located proximate a first edge of the plurality of edges, the second antenna is located proximate a second edge of the plurality of edges. The system includes a switch communicatively coupled to the first antenna and the second antenna, and a processing resource communicatively coupled to the switch. The processing resource is configured to determine a first orientation of the portable information handling system; based on the first orientation, designate the first antenna as a primary antenna and designate the second antenna as a secondary antenna; and direct the switch to transition the primary antenna to an active state and direct the switch to transition the secondary antenna to an inactive state.
