    Abstract: A device for supporting wireless communication is provided. The device includes a transceiver, an antenna, and a radio frequency (RF) front end system communicatively coupled to the transceiver and the antenna. The RF front end system may include: a RF sampling block coupled to the transceiver and configured to sample signals received from the transceiver and output voltage signals; a RF switching logic coupled to the RF sampling block to receive the voltage signals and configured to switch the front end RF system between a transmitting mode and a receiving mode; a RF transmission gain block coupled to the RF switching logic and configured to increase a transmission power of the signals received from the transceiver; and a RF receiving gain block coupled to the RF switching logic and configured to remove noise signals contained in radio frequency signals received from the antenna.

    Abstract: A device for supporting wireless communication is provided. The device includes a first Bluetooth transceiver for communicating with a Bluetooth device, a second Bluetooth transceiver for communicating with a client device, one or more processors, and a memory for storing instructions executable by the one or more processors. The one or more processors may be configured to establish, via the first Bluetooth transceiver, a first communication connection with the Bluetooth device, and transmit, via the second Bluetooth transceiver, a Bluetooth broadcast signal indicating an availability of the Bluetooth device, and establish, via the second Bluetooth transceiver, a second communication connection with the client device. The one or more processors may be further configured to receive, data directing to the Bluetooth device, from the client device via the second communication connection, and forward, the data directing to the Bluetooth device, to the Bluetooth device via the first communication connection.

    Abstract: Devices, systems, and methods are disclosed for detecting falls and transmitting notifications. One embodiment includes a wearable device. The wearable device may include a first sensor configured to collect acceleration data, and at least one of a second sensor configured to collect pressure data or a third sensor configured to collect temperature data. The wearable device may also include an antenna and a processor. The wearable device may also include a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to receive the acceleration data and at least one of the pressure data or the temperature data, process the acceleration data and at least one of the pressure data or the temperature data, and control, when the processor determines that a person falls, the antenna to transmit a signal.
