According to the adjustment experience of multiple networks, improving the overall transmit power is beneficial to the road test, and reducing the overall transmit power improves the overall network KPI (receive quality, call drop rate, etc.). When adjusting parameters, you need to make trade-offs based on the focus of the network assessment.

The effects of tower amplifiers on the system are: (Multiple choice)

• A.When the base station's own noise figure is small (ie, the receiving sensitivity is high) and the feeder is short, the improvement of the noise figure of the receiving system of the base station after the increase of the towering amplifier is great.
• B.The tower top amplifier reduces the noise figure of the base station receiving system, thereby improving the receiving sensitivity of the base station system;
• C.When the base station feeder is long and the feeder loss is large, after the tower top amplifier is increased, the noise figure improvement (reduction) of the base station receiving system is more obvious, and the uplink improvement is obvious;
• D.When the noise figure of the tower top amplifier is small, the noise coefficient improvement of the base station receiving system is more obvious after the tower top amplifier is increased, and the noise figure of the tower top amplifier is too large, which may cause the noise figure of the base station receiving system to deteriorate;
