專利摘要：
A smart communication system, for adaptive antenna beam-forming for a link of a data transmission device to at least a user device, is introduced. The system comprises a plurality of positioning devices, a data transmission device, and a cloud server. The positioning devices send a plurality of positioning signals to the at least a user device to effectuate positioning. The data transmission device is for use with adaptive antenna beam-forming to provide wireless communication. The user device communicates with the cloud server through the base station unit. The cloud server receives positioning information of the at least a user device, generates a control signal for beam-forming in accordance with the positioning information, and sends the control signal to the data transmission device. The data transmission device controls the beam-forming of the data transmission device in accordance with the control signal.
