As 5G network operating frequency bands are allocated higher and higher, the coverage depth of outdoor base stations for indoors is becoming increasingly insufficient. In densely populated areas such as hotels, shopping malls, office buildings, etc., room division equipment is needed to evenly distribute the source signal to the indoor area to be covered, so as to improve the indoor mobile communication environment.

Traditional satellite positioning systems have weak signals and are easily occluded and interfered. It is difficult to accurately locate and navigate in high-rise buildings, narrow alleys, or environments with multiple signal base stations. With the completion of the global deployment of Beidou satellites, Beidou navigation products are about to face comprehensive optimization. Beidou navigation products are required to complete positioning and navigation tasks stably and reliably in a variety of space environments, electromagnetic environments, dynamic environments, and temperature environments. Therefore, related connector products must have excellent performance such as anti-interference, high precision, and high sensitivity at the same time.
