Base Station Monitoring System
Monotoring Method
Monitor and log RF performance of Base station
Send the RF performance information to the server
Alarm user for the BTS with unstable RF performance
Monitor and log RF performance of Base station
Send the RF performance information to the server
Alarm user for the BTS with unstable RF performance
Monitoring system to achieve the good quality of Base station
operation and maintenance in Wireless Network
(WCDMA/HSDPA/CDMA/EVDO/WiMAX
Advantages
Reduce the cost for the BTU (Base station test unit) of base station
Reduce the cost to maintain base stations due to monitoring remotely
RF performance of base stations supplied by different system vendor
can be managed consistently by service provider
Other information such as capacity, Tx power consumption and others
can be achieved by BMS
