Airgain, Inc.
A maker of wireless connectivity gear, Airgain designs embedded antennas, 5G smart repeaters (Lighthouse), embedded modems (NimbeLink), and vehicle gateways like AirgainConnect Fleet for consumer, automotive, and industrial devices. Based in San Diego, the company took the Airgain name in 2004 when it refocused on antennas alone — pairing "air" for the waves and "gain," the engineering term for how well an antenna converts signals into radio waves.
