Transcelestial creates laser wireless with 25 Gbps speeds

Singapore-based startup Transcelestial invented a laser communications technology that uses infrared spectrum to connect under-served people around the world to the internet. “The cost to connect the world is not commercially viable if upgrades depend on the rollout of new fiber cables,” said Mohammad Danesh, co-founder and CTO of Transcelestial. The company’s Centauri 25G product delivers 25 Gbps internet connectivity via laser beam, eliminating the need for underground cables or radio frequency-based devices. The technology can connect buildings point-to-point in less than a day. Centauri does not broadcast signals like traditional wireless. Rather, it’s a point-to-point solution that is deployed similarly to microwaves on traditional cell towers, street-level poles, and other physical infrastructure. The Centauri device is about the size of a shoebox and it uses less than 20 watts of power. In urban areas, the devices can be deployed to create a wireless mesh.
