Transcelestial’s vision is to improve the connectivity experience for the next billion people. We believe that connectivity is a human right and Transcelestial is on a mission to solve the problem of internet distribution and provide affordable, high-speed internet to everyone.

Transcelestial’s next-generation wireless laser communication technology is one of the most effective solutions in the distribution of high-quality, high-speed internet connectivity, making it well-poised to solve civilization’s long-term communication needs - and ultimately improve connectivity for 1 billion users globally.

Highly reliable and secure, its light-weight, shoe-box sized CENTAURI device leverages its proprietary laser technology to create a wireless distribution network and can be quickly, easily and cost-effectively installed on any standard telecom pole or tower at a faster time-to-market than standard fiber-optic cable.

Over the longer-term, Transcelestial aims to develop a constellation of small satellites positioned in Low Earth Orbit, allowing their laser network to not only beam across cities but upwards to connect continents across the world too.
