Abstract
A wireless network apparatus, comprising a weighting device. The weighting device, includes a weight generator, and an algorithmic unit, and is for receiving and multiplying digital input signals from an antenna by a weight vector to output a digital weighted signal. The invention searches for the location of the client by detecting its signal strength and moving the main beam generated by the antenna array towards the client using an adaptive digital beamforming method according to proposed algorithms. The method searches for a client by: first, searching a main central angle C; then, determining a weight vector in response to the main central angle C; fine-tuning the main central angle C; and forming a main beam according to the fine-tuned main central angle and the weight vector.
