How to Overcome Challenges in the Bidirectional Communication of LPWAN with MIOTY

12. NOV 2020

Lecture electronica Conferences > Wireless Congress > Session 13: Mioty II

14:00-14:25 h | Virtual

Low-power wide-area networks (LPWANs) are a key technology in building up the Internet of things. LPWANs are introduced in a rising number of application areas like condition monitoring, building automation or transport and logistics. The mioty technology mainly developed by Fraunhofer IIS and promoted by the mioty Alliance stands for a LPWAN protocol based on the ETSI standard TS103357 with minimum power consumption and high scalability for massive IOT. LPWAN technologies are operated in the license free spectrum and share the same frequency band with a variety of other wireless technologies. In addition, the same band or two adjacent bands are used for uplink and downlink in networks with bidirectional communication. As a result only half-duplex operation is possible, which reduces the cost for duplex filters, but has some other challenges, when serving a massive number of devices from a single basestation. Whereas the packet error rate of traditional LPWAN systems massively suffers in half duplex operation, the packet error rate of telegram splitting systems is practically not affected. This presentation will give an overview of the mioty technology and the innovative approach of Telegram Splitting Multiple Access (TSMA). The current frequency regulations and the resulting challenges to the duplex operation of a LPWA network and the fulfillment of certain application requirements will be discussed. Finally it will be explained, how mioty and the telegram splitting approach will overcome this challenges.
