Abstract
The goal of this research report is to objectively evaluate the performance of emerging DECT-2020 standard. The DECT-2020 standard from European Telecommunications Standards Institute (ETSI) is a candidate technology for International Mobile Telecommunications 2020 (IMT-2020) wireless technology. The target use scenario involves the massive machine type communications (mMTC) in an urban macro wireless channel environment. The International Telecommunication Union (ITU) sets the requirements for any IMT-compliant mMTC technology. Essentially, the supported device connection density must be at least 1 million devices per km2 while the packet outage rate and packet delay must be at most 1 % and 10 s, respectively.
The used simulation environment is developed using the well-recognized Network Simulator 3 (NS-3) software in order to estimate the packet outage rate constrained by the packet delay and network density. The comprehensive system simulator can handle both the device association phase as well as the application data transmission phase according to the DECT-2020 standard specifications. A distinctive system parameter of interest is the proportion of routing devices out of all source devices in the mesh network.
It is concluded that, for the given evaluation framework, the DECT-2020 is able to fulfil the aforementioned ITU requirements and it appears, therefore, a potential candidate for the IMT-2020-enabled mMTC digital services. During the project, VTT’s results also contributed to the ETSI evaluation group work and were used in corresponding interim evaluation report submitted to ITU-R by ETSI.
The views and results of this report are those of authors.
