ITU Satellite Webinars 2020

The International Telecommunication Union (ITU), is a specialized agency of the United Nations responsible for all matters related to information and communication technologies. Established in 1865 as the International Telegraph Union, it is one of the oldest international organizations in operation. The ITU promotes the shared global use of the radio spectrum, facilitates international cooperation in assigning satellite orbits, assists in developing and coordinating worldwide technical standards, and works to improve telecommunication infrastructure in the developing world.  The ITU recently held a series of Satellite Webinars to share the current technical and regulatory situation, evolution, and trends in the field of satellite communications. They featured discussions and contributions from well-known experts from the satellite and space industries and were open to ITU members and non-members alike! Part 1 - ​Interference to Satellite Systems: preventing or protecting? : From case

SuperCell, a Wide-Area Coverage Solution for Increasing Mobile Connectivity in Rural Communities

In this blog we have looked at lots of different solutions to improve rural and remove connectivity (see related posts at the end of this post). Now Facebook Connectivity has announced that they have been working on prototyping the SuperCell, a wide-area coverage solution for increasing mobile connectivity in rural communities. After working with telecom industry partners to conduct several trials and data analyses, they are ready to share what they have learned. From the Facebook Engineering blog post :  SuperCell is a large-area coverage solution that leverages towers up to 250 meters high and high-gain, narrow-sectored antennas to increase mobile data coverage range and capacity.   Our field measurements found that a 36-sector SuperCell base station mounted on a 250-meter tower can serve a geographical coverage area up to 65 times larger than a standard three-sector rural macro base station on a 30-meter tower in the same topography. In an analysis of uncovered regions in Nigeria,

Connecting LEO and GEO Satellites with Inter-satellite Data Relay System (IDRS)

While there is no shortage of challenges for satellites, especially the low earth orbit or LEO satellites, one of the tricky ones is to to ensure some kind of continuous connectivity to a ground station. LEO satellites orbit the earth roughly every 90 minutes and are in contact with their ground station for roughly 4% of the orbit. To have a continuous connectivity available on demand, Inmarsat and Addvalue Innovation announce real-time link between satellites with promise of quicker delivery of data and imagery across the globe. The press release says : The world’s first ever publicly-available, real-time link between satellites in high and low earth orbits is now available, it was announced today. After a five-year collaboration, Inmarsat and Addvalue Innovation are pleased to announce the Commercial Service Introduction (CSI) of their Inter-satellite Data Relay System (IDRS) service, following the successful demonstration of the first live data connectivity between customer Capella
