Design of Beidou Communication Terminal Using Multi-SIM Cards Multiplexing
Zhan Wen · Telecommunication Engineering · 2010
In order to expand the application scope and reduce the cost of the first generation Beidou terminals,this paper proposes a Beidou terminal design scheme using multi-SIM cards multiplexing.This design scheme uses FPGA + ARM hardware architecture,increases the number of SIM cards,and realizes data automatic fragmentation and collaborative work of the multi-SIM cards through software design,thus enhancing the data transmission rate of the Beidou terminal.This method has been successfully deployed in Oil and Gas Well Remote Monitoring System in the field.
