An omnidirectional optical communication system. The omnidirectional optical communication system includes a multifaceted structure, a laser transmitter with a steerable mechanism, an optical detector receiver, and an angle-of-arrival system. In one aspect, the laser transmitter with a steerable mechanism, the optical detector receiver, and the angle-of-arrival system are housed in within the multifaceted structure, which enables omnidirectional optical communication. In another aspect, the omnidirectional optical communication system is used in a spacecraft for inter-spacecraft omnidirectional optical communication. In yet another aspect, the omnidirectional optical communication system is used in terrestrial applications for gigabit communications in WiFi, inter smartphones, internet of things and smart cities. In yet another aspect, the omnidirectional optical communication system further includes a global positioning system.
