Terrestrial IoT solutions (e.g. LTE or LPWAN) are cost-efficient on the device side (a low cost connectivity module can easily be integrated in any device) but is expensive on the network side (a large number of Base Transceiver Stations supporting antennas and backhaul connectivity is required). Therefore, terrestrial IoT will be primarily rolled out in the most densely populated areas, and this will limit IoT services adoption outside Smart Cities, particularly for those Industrial IoT applications (Industry 4.0) requiring large coverage areas or global seamless connectivity.
Space IoT solutions have the potential to bridge this coverage/adoption gap. However, although it is cost effective on the network side (as one satellite can cover large geographical areas), it remains expensive on the device side. Satellite communications are traditionally oriented around high-bandwidth voice and data connections which require high transmit power, so there are few chipsets and devices operating at low data rates with long battery autonomy (>6 yrs). Personal Navigation Devices (based on GPS or Glonass) use simple data formats and provide only Position Navigation and Timing (PNT) data. Existing space IoT solutions work best with relatively large and costly terminals with very limited power autonomy aggregating local IoT networks.
Space IoT has the potential to compete with terrestrial IoT in terms of cost, size and energy autonomy if it can develop an appropriate communications standard and truly autonomous small mobile sensors capable of communications via satellite. Based on market research (Northern Sky estimates a €2Bn market for 2.75M Space IoT enabled devices by 2022), the consortium has identified a large opportunity for a European space based solution for LPWA (Low Power Wide Area).
To address this opportunity, the space technology transfer venture S4M was formed in 2014 to develop a novel technology platform, network and architecture for Space IoT called TELDASAT . TELDASAT leverages existing and planned European space technology infrastructure (such as the German Space Operations Center at DLR) and expertise to create a new approach to space IoT benefiting from an exclusive access to space and a distinct “first to market” advantage. This project seeks to develop the IoTEE sensor device, supporting any type of data that can be gathered and transported via the S4M short data messaging system: temperature, pressure, vibration, open/closed, leak indication, broken alarm, km counting, position, speed, among others.
The project will enable a space-based solution to fill the IoT coverage/adoption gap, providing a unique opportunity for Europe to accelerate its IoT deployment, particularly in areas outside the “Smart City War” where most terrestrial IoT development is currently concentrated. The project will therefore enable accelerated IoT adoption across many key sectors – such as energy, transportation, security, agriculture, environment, and industrial automation – generating broad business and societal impacts. The project complements the Smart Cities approach with a “Smart Countryside”, addressing key EU societal challenges across sustainability, transportation, pollution reduction and climate change risk mitigation.
