【Abstract】 CDMA2000 1x is a high capacity system with excellent spectrum efficiency,transmission quality,security,coverage and low drop rate. It is ideal for high speed data transmission that has no strict limit on the decoding delay. Transmitting data with a CDMA2000 1x system in real-time will decrease the drop rate,power consumption of the radio,and overall interference level and increase the stability and availability of the system,in compliance with the requirements of seismic signal transmission.更多还原
