The present invention mainly discloses an electronic device for controlling intelligent antenna module based on intelligent fast antenna steering technology (iFAST), wherein the electronic device is applied in wireless network transceiving device. Particularly, according to the wireless network parameters of wireless signals received by a wireless network transceiving device from wireless stations established connections with the wireless network transceiving device, an iFAST unit in the electronic device would immediately update relative MAC station entry tables in a MAC module, such that the baseband processor module would correspondingly adjust the settings of the intelligent antenna module of the wireless network transceiving device based on relative wireless station entry records been established in the MAC station entry tables contained by the MAC module. As a result, the wireless network transceiving device is ensured to radiate customized wireless network signals to cover the targeted wireless stations.
