Session
Technical Poster Session IV
Location
Utah State University, Logan, UT
Abstract
In December 2019, 3GPP have for the 5G specification decided to separate the Narrowband IoT Non-Terrestrial Network (NB-IoT NTN) from the New Radio NTN. Due to this change, NB-IoT NTN becomes a very attractive candidate for LEO IoT satellite constellations.
The decision emphasises that there is a strong push for cellular standards into the space industry and that commercial utilizations in large scale is getting closer. However, it also entails significant technical challenges in terms of connectivity, backhaul integration and operational features. GateHouse Telecom currently work on an ARTES supported project (Narrowband IoT standard for small satellites). Based on the existing 3GPP terrestrial NB-IoT standard the purpose of this project is to identify areas of adaptations to utilize this from space. Further, the project will provide solutions to overcome the waveform challenges related to doppler, latency, timing, propagation loss etc.
This poster provides initial results from the project in terms of architecture, suggested adaptations and technical challenges related to architecture and implementation.
