An antenna adjustment system and a base station, where the antenna adjustment system includes an inertial feedback unit configured to detect a swing angle of an antenna when the antenna swings with a housing, and send an angle signal to a controller, an actuator and an elastic element configured to control an auxiliary board to rotate back in a direction opposite to a swing direction of the housing in order to counteract deflection caused by swing of the housing of the antenna fastened to the auxiliary board. The actuator is driven by the controller based on the angle signal. Therefore, a position of an antenna can be adjusted with swing of the antenna such that signal sending stability of the antenna can be ensured.

Antenna adjustment system and base station

A terminal, a color changing method, and a color changing apparatus that relate to the field of communications technologies are provided, so as to resolve a technical problem of a waste of materials due to production of a terminal shell. A color changing unit is disposed inside a terminal, where the color changing unit can change a color when receiving electrical energy, and a transparency value of a shell is greater than a first preset transparency value, so that a technical problem of a waste of materials due to production of a terminal shell can be effectively resolved, which can reduce manufacturing materials and is conducive to environmental protection.

Terminal, color changing method, and color changing apparatus

The present invention discloses a communications product (), including a remote radio module () and a mounting kit (), where the mounting kit () includes a fastening part (), the fastening part () is configured to mount and fasten the remote radio module () to a holder, the mounting kit () further includes a ventilation part () and an air supply part (), an air source is disposed inside the air supply part (), the ventilation part () is connected between the fastening part () and the air supply part (), a ventilation channel is disposed inside the ventilation part (), and the ventilation channel allows the air supply part () to communicate with the remote radio module (), so that an air flow generated by the air source reaches the remote radio module () after passing through the ventilation channel, to dissipate heat for the remote radio module.
