Design and Application of Teledata Collection System Based on TRF6900

TRF6900, made by TI Company, is a single-chip solution and integrated circuit used as a low-cost RF Transceiver for 850MHz-950MHz ISM Bands. In contrast with those common RF single-chips, TRF6900 is more adaptive to work in a complex environment, which means the environment may be full of electromagnetic interference or the space is restricted. The functions of TRF6900 are analyzed, based on which, the practical application is demonstrated in constructing a wireless mobile communication system used for teledata collection. The system has improve the speed and efficiency of the teledata collection. The result proved that this system is worthy of using underground.
