| Abstract(in English) | LoRa networks achieve a remarkable wide coverage by exploiting the chirp spread spectrum (CSS) technique. However, a single-hop LoRa network still has a limitation in indoor environments and cannot efficiently utilize the capacity gain given by different spreading factors (SF). As the first step to verify the feasibility of constructing an efficient multi-hop LoRa network using diverse SFs, we evaluate the LoRa receiver performance under the mutual interference. The results show that LoRa can survive the interference from the time-synchronized packets with an identical SF with a close to zero signal-to-interference ratio (SIR). Also, we verify that LoRa can survive different SF interference with a much lower SIR due to the orthogonality between SFs. |
