Overview:

CDMA network operations require high-precision time synchronization. To achieve this, each CDMA base station is equipped with a GPS or Beidou receiver to synchronize with UTC time, ensuring synchronization between base station equipment and CDMA users within the base station's service range. The base stations also have satellite signal monitoring and high-precision timekeeping capabilities to provide reliable time accuracy.
 

 
The TWN100C CDMA digital clock is a high-precision time display digital clock designed and developed by our company. This product integrates CDMA receiving module, industrial-grade motherboard, and digital display unit. It does not require a SIM card and there are no usage fees. It can conveniently obtain UTC time information through the CDMA network and can be easily deployed in any location with CDMA signal coverage. Additionally, because the CDMA antenna can be placed indoors, it can completely eliminate the damage caused by lightning storms to the equipment.
 

 
All digital clocks have independent timing functions and track CDMA network time signals. Even when the clocks do not receive CDMA network time signals, they can still operate independently using their own crystal oscillators. The clocks start running automatically when powered on, refreshing themselves and staying consistent with Beijing time. The clocks rigorously compare, analyze, and judge the received information to eliminate interference from abnormal messages.
 
The clocks can be installed by wall mounting (default), suspension, or embedded installation, depending on the site environment. These clocks are widely used in important locations such as schools, airports, train stations, subways, dispatch centers, and wartime command centers.
