(DBPSK) and the Gaussian frequency shift keying (GFSK) that enables communication using the Short-range device band of 868 MHz in Europe, and the Industrial, Scientific and Medical radio band of 902 MHz in the US. It utilizes a wide-reaching signal that passes freely through solid objects, called " Ultra Narrowband" and requires little energy, being termed a " low-power wide-area network" ( LPWAN). The network is based on one-hop
