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

• A.The tower top amplifier reduces the noise figure of the base station receiving system, thereby improving the receiving sensitivity of the base station system;
• B.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.
• 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;

T3212 (periodic location update time limit) of different cells in the same location area in the BSC is recommended to be set to be the same, and is smaller than the periodic location update time set in the MSC.

• A.True
• B.False

In which area is paging performed?

• A.BTS
• B.LAC
• C.BSC
• D.MSC

The calculation formula of the wireless handover success rate indicator is the number of successful handovers/number of handovers. If the wireless handover success rate is low in traffic statistics. Which of the following are the possible reasons? (Multiple Choice)

• A.The neighbor relationship relationship of the target cell is not defined in the cell neighbor relationship table.
• B.The uplink signal of the target cell is weak and cannot be accessed;
• C.The BSC external cell table describes an error, causing the CGI of the target cell to be found wrong, and after the other cell activates the channel, but cannot access.
• D.The target cell is not a true target cell, but a pseudo target cell with the BSIC of the BCCH.
