【Patents from Five-Year Exploration】
The wireless maintenance team of the Tianjin Branch's network monitoring center often encounters complaints about unstable mobile communication
signals and unsatisfactory network speeds in their daily work. After repeated investigations, the team found that the traditional measurement method used
to measure the antenna angle in the high magnetic area was not accurate, resulting in significant errors; moreover, the technicians had to frequently climb
up base stations for commissioning, which caused high security risks and high costs.

In order to quickly adjust the angle of the base station antenna, it is necessary to collect a large amount of data, establish an accurate antenna angle
data file, and obtain the best angle through simulation. Since 2014, the wireless maintenance team has used their spare time to carry out special research
while completing its own work, and had explored a set of "data-based" and "systematic" antenna direction angle measurement methods, so that the
consistency ratio between actual and planned antenna angle in a high magnetic environment was increased from the previous 23% to 99%, serving as a
more accurate tool for optimizing the antenna angle. In November 2019, the research results of the "antenna direction angle measurement method and
device" proposed by the wireless maintenance team passed the review and authorization for national invention patents and was promoted nationwide.
