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.

Method for sending recommendation information and positioning service device

A gateway for Internet of Things including a body, a main control board, and antenna components located on the body and including a short-range communication antenna component, a 5G antenna component and a Wi-Fi antenna component. The short-range communication antenna component, the main control board and the Wi-Fi antenna component are successively arranged on the body along a first direction of the body, a vertically upward direction of the body during the use of the gateway for Internet of Things being determined as the first direction of the body. A long-axis direction of the main control board is set parallel to the first direction of the body. The 5G antenna component includes at least one pair of two antennas arranged on both sides or the same side of a largest face of the main control board outside one or two sides along the first direction of the body.

Gateway for internet of things

A color setting method includes: displaying multiple groups of color pictures respectively according to a pre-set sequence, each group of color pictures including at least two pictures, and each picture including at least one color component; marking a selected picture in each group of color pictures in response to a first operation by a user; acquiring a user's color preferences according to a plurality of selected pictures and color components of each picture; setting color parameters of a display device according to the color preferences.
