A positioning method and a positioning system based on light intensity are provided. The positioning system comprises a lighting system, a sense feedback device and a positioning module. The lighting system comprises at least three point light sources and sequentially adjusts luminance of these point light sources to light up a target. The sense feedback device is disposed on the target and used to collect light intensity information of the light projected on the target by the lighting system. The positioning module calculates a distance between the target and each of the point light sources based on the light intensity information and calculates a positioning location of the target based on the locations of the point light sources and the distances between the target and the point light sources.

An apparatus for a beacon-enabled wireless network, a transmission time determination method, and a tangible machine-readable medium thereof are provided. The apparatus is located within the coverage area of the first equipment. The second equipment is located within the coverage area of the apparatus. The apparatus comprises a receive/transmission module and a decision module. The receive/transmission module is configured to receive the beacon of the first equipment. The decision module is configured to decide information of an upload time slot and a download time slot of the apparatus according to the beacon so that the receive/transmission module can perform data transmission with the first equipment by the upload time slot and perform data transmission with the second equipment by the download time slot. According to the aforementioned allocations, transmission collisions can be avoided and delay of transmission times is decreased.
