This study aims to provide alternative of an intermediate class of SDR features with high-end characteristic which is efficient and flexible in cost and implementation. Modulation and demodulation SDR based Frequency Shift Keying scheme is proposed using HackRF as an alternative SDR hardware with high-end characteristic. This study is an experimental study. Simulation carried out to measure the performance of the proposed model. Proposing HackRF for SDR transmitter based FSK scheme.
