Direct-to-Satellite IoT allows devices on the Earth surface to directly reach Low-Earth Orbit
(LEO) satellites passing over them. Although an appealing approach towards a truly global …

Direct-to-Satellite IoT (DtS-IoT) is a promising approach to deliver data transfer services to
IoT devices in remote areas where deploying terrestrial infrastructure is not appealing or …

In the next few years, low-Earth orbit (LEO) constellations will become key enablers for the
deployment of global Internet of Things (IoT) services. Due to their proximity to Earth, LEO …

We investigate the packet collision probability among uncoordinated devices, in the uplink of
DtS-IoT. Both the satellite spot shape and its motion along its orbital path are considered in …

Direct-to-Satellite-IoT (DtS-IoT) is a promising approach for data transfer to/from IoT devices
in remote areas where deploying terrestrial infrastructure is not appealing or feasible. In this …

The Long Range (LoRa) modulation enables low-cost and low-power communications,
serving as the foundation for the widely adopted terrestrial low-power wide-area network …

There has been increasing interest in the Internet of Space Things (IoST) paradigm, an
extension of the traditional Internet of Things (IoT) system based on using satellites to serve …

A global Internet of Things is possible by embracing constellations of satellites acting as
orbiting gateways in a Direct-to-Satellite IoT (DtS-IoT). By removing the dependency on …

In this article, we introduce and design sparse constellations for direct-to-satellite Internet of
Things (DtS-IoT). DtS-IoT does not require a ground infrastructure, because the devices are …

Direct-to-satellite Internet of Things (IoT) solutions have attracted a lot of attention from
industry and academia recently, as promising alternatives for large scale coverage of a …
