Abstract

A portable wireless signal transfer system, method and terminal. The method comprises: a first terminal receiving a wireless signal; the first terminal demodulating the wireless signal to obtain burst data and a timeslot number; the first terminal sending the burst data and the timeslot number to a second terminal; the second terminal receiving the burst data and the timeslot number sent by the first terminal; the second terminal performing signal modulation on the burst data; and the second terminal transmitting a signal obtained after the signal modulation in a corresponding timeslot according to the timeslot number.
