Abstract
The present disclosure discloses a method for sending recommendation information and a positioning service device. The method includes: receiving feedback signals sent by user terminals within a signal coverage range of the positioning service device, where each feedback signal carries a first signal strength and a first signal direction of a radio-frequency signal sent by the positioning service device and received by the corresponding user terminal; determining, according to the first signal strength and the first signal direction corresponding to each user terminal, a main region where the user terminals are concentrated within the signal coverage range; and adjusting a signal sending direction of each radio-frequency signal to a direction where the main region is located and sending the recommendation information, where the recommendation information is borne by the radio-frequency signals.
