Summary:
Low Power Wide Area (LPWA) systems suitable for IoT have been widely deployed. However, collisions and interferences become a severe problem in high-density networks. This paper applies the asynchronous pulse code multiple access (APCMA) communication scheme to a massive IoT environment. APCMA uses pulses for data transmissions and is effective for high-density wireless environments. We have designed a CSS-APCMA that satisfies a Japanese regulation standard ARIB STD-T108 and developed 500 transmitters. We evaluate the performance of simultaneous communications up to 500 transmitters by experiments in an actual environment. Our experimental results show that the proposed system has a high performance even in a high-density environment.
