Adopting 89c52 monolithic microcomputer kernel and timer catching mode with MAX483 telecommunication modular and DC/DC power modular and utilizing software-hardware integrated telecommunicating function, this design realizes transformation of current/frequency through transformation of A/D that is convenient for digital output.
Multiple Regression Analysis indicates that quality of tourist service has a direct effect as to the length of stay of inbound tourists to China, especially the service given by hotels, guiding and telecommunication service.
It is questionable for the International Telecommunication Union (ITU) to select the frequency band of 2 GHz for vehicular mobile telecommunication and unreasonable to distribute it over the downlink and uplink channels symmetrically.
Time difference of arrival (TDOA) is the positioning technique with the most potential in cellular mobile telecommunication systems.
Typical subsystems of complex telecommunication networks, such as computing systems, two-pole data transfer networks and others, are investigated.
