Zusammenfassung:	A Long Range (LoRa) communication system with an improved data rate and method thereof are provided. When a packet to be transmitted is received, a transmission device determines a transmission scheme. When the determined transmission scheme is an enhanced transmission scheme, the transmission device transmits a preamble signal indicating that a packet is to be transmitted using the enhanced transmission scheme, converts n-th data of the packet to an up-chirp signal, converts (n+1)-th data of the packet to a down-chirp signal, generates a transmission signal by adding the n-th data converted to the up-chirp signal and the (n+1)-th data converted to the down-chirp signal, and transmits the transmission signal to a reception device.
