The transmitting apparatus includes a transmitting processing unit, configured to determine a wireless transmission channel on a first frequency band when in a first mode; a transmitting antenna unit, configured to transmit information of the wireless transmission channel and a channel state information of the wireless transmission channel on a second frequency band when in the first mode of the transmitting apparatus; and a wireless sensing unit, configured to perform a wireless sensing on the wireless transmission channel when in a second mode of the transmitting apparatus.

Wireless communication system, method and related transmitting apparatus

A lighting apparatus and a system for indicating locations within an area are provided. The system includes a plurality of lighting apparatuses that are installed at different locations within the area. The lighting apparatuses form a mesh network. Every lighting apparatus is assigned with an identifier for locating the lighting apparatus with a color or a pattern. The lighting apparatus includes a control circuit that controls the lighting apparatus to operate with a first mode or a second mode. The apparatus includes a lighting unit that can be activated to illuminate color or pattern on a region for indicating where the lighting apparatus is located under the second mode. In an aspect, the area is divided into multiple regions that are indicated by different combinations of colors and patterns illuminated by the lighting units of the lighting apparatuses separately.

A repeater and a synchronization method for the same are provided. The synchronization method includes: configuring a base station to transmit an input signal during downlink transmission durations according to a time division duplex (TDD) configuration, in which the TDD configuration defines a predetermined pattern composed of an uplink transmission duration and a downlink transmission duration; configuring a processor generate a received signal code according to the input signal; configuring the processor to sample the received signal code by using a signal window to generate a target pattern; configuring the processor to dynamically compare the target pattern with the predetermined pattern according to the TDD configuration, positions of the received downlink transmission durations and positions of the received uplink transmission durations stored in a memory of the repeater, and determine whether the target pattern matches to the predetermined pattern.

A lighting apparatus, a method and a system for processing an emergency procedure are provided. The system includes two or more lighting apparatuses that are interconnected for forming a mesh network over an area. In the method, the lighting apparatus is activated to illuminate a surveillance zone under an emergency mode. In the meantime, a camera circuit is driven to capture a series of images of the surveillance zone for conduct motion detection. When a moving object is detected, the lighting apparatus transmits a beacon signal in response to the detection result. In the meantime, an acknowledgement signal in response to the beacon signal is generated by a signal source and received by the lighting apparatus. After that, the identifier with respect to the lighting apparatus is transmitted to a control center for obtaining the position of the lighting apparatus.

A structure detection system and method for detecting anomalies associated with the structure are provided. The system includes a first transceiver, a second transceiver, and a processor. In a first TR test, the second transceiver receives a first probing signal sent from the first transceiver and performs a time-reversal (TR) process to generate a first TR signal to be sent to the first transceiver, and a first channel state information (CSI) is obtained in response to the first TR signal. In a second TR test, the first transceiver receives a second probing signal sent from the second transceiver and performs the TR process to generate a second TR signal to be sent to the second transceiver, a second CSI is obtained in response to the second TR signal. The processor compares a combination of the first CSI and the second CSI to a reference CSI for detecting anomalies.

Anomalies detection system and method for structure

An indoor positioning system and an indoor positioning method allow all of the wireless base stations and mobile terminals in the same interior space to synchronously generate their time slots. Further, each mobile terminal transmits a positioning signal only at a preset time point in each time slot to prevent collisions between mobile terminals transmitting the positioning signals.

Indoor positioning method and system thereof preventing signal transmission collisions

A wireless communication device for linking to an electronic device and including at least one antenna array and a control circuit is provided. The control circuit groups the at least one antenna array to obtain a plurality of test groups. In a scanning operation, the control circuit selects one of the test groups to be a specific test group. In a setting operation, the control circuit groups the specific test group, and re-obtains the plurality of test groups according to the grouped specific test group. The control circuit searches at least one optimal antenna for linking to the electronic device from the at least one antenna array through the scanning operation and the setting operation.
