Discover how Deutsche Telekom is setting new standards in IoT connectivity! For the first time, a mobile operator enables global multi-orbit roaming for the Internet of Things, allowing IoT devices to reliably transmit data worldwide via terrestrial and satellite (LEO/GEO) networks. Our new NB-IoT connectivity offering already includes access to the non-terrestrial networks of Skylo, OQ Technology and Sateliot, and will soon be expanded by Iridium’s constellation. 
Real-world applications, such as Datakorum’s water management and Digitanimal’s livestock tracking, demonstrate these advancements in action. Join us to learn more about the future of global IoT networking from industry experts and users.

Carlos Callejero is CEO and co-founder of Digitanimal, a company founded in 2015 to locate and monitor extensive livestock. Digitanimal now offers a comprehensive livestock management system that provides and interprets a wide range of data to improve the productivity of livestock farms.

The need to connect animals has led Digitanimal to collaborate with DT from the development of the first NB-IoT GPS tracking devices to the present day. 

A PhD in Physics and an expert in millimeter wave and THz systems, he has participated in several working groups of the Spanish Ministry of Agriculture, NATO and EDA, and has been a co-founding partner in several technology companies.
