Weak 2G 3G signal and no 4G signal. Dropped calls and poor internet access.
The coverage area is scattered, and the workshop structure is complex. Some area is interlining.
Building materials are also complicated with glass, brick walls, and color steel plates altogether.
Customer needs the signal for all local carriers, yet 4G signal loss is large, and the periodic line is long.
We made the 1/2 cable line with correct connector, and connect the input end, output end, and coupling end precisely accurate. After rigorous construction, each of 2G, 3G and 4G signal became much stronger in the testing instrument. Then we attenuated the parameter in accordance with the actual data and restarted the host for customer’s own testing. They were satisfied with the signal coverage, and no more signal issues.
