Abstract

The present invention discloses a wireless access data terminal and a system and a method for realizing data communication in order to solve the problems that the existing wireless access data terminals have large power consumption and large heat release amount and cause the low use rate of the central processing units (CPU) of general computers. The system for realizing data communication with a wireless access data terminal comprises a wireless access data terminal. The wireless access data terminal is used for mixing frequencies for downstream wireless signals from an air interface and obtaining downstream digital IQ signals through analog-to-digital conversion. The downstream digital IQ signals are converted by a bus protocol and then connected to the system bus of the CPU of a general computer. The wireless access data terminal is also used for carrying out digital-to-analog conversion for upstream digital IQ signals obtained by converting upstream digital information output by the CPU with the bus protocol, and modulating and sending out wireless signals. The CPU of the general computer is used for carrying out data business processing for the downstream digital IQ signals received by the system bus and sending out upstream digital information needed to be sent out through the system bus.
