About EridanAt Eridan we believe in the power of collaboration and communication to achieve our mission: connect the planet to empower a sustainable, shared future. That mission is possible with our patented transmitter which decreases the cost and power required to roll out 5G by 10x when deployed globally. This is all facilitated through our offices: our Sunnyvale headquarters has big windows (even in the lab!), is walking distance to downtown and the Caltrain, and fits the entire team in the cafeteria for our frequent company parties.
