ALOHA Experiment

The ALOHA Experiment was an early test of a pioneering wireless communication system, designed to explore how multiple devices could share a common communication channel efficiently. It demonstrated the concept of "random access," where devices transmit data whenever they need to, without waiting for permission. If a collision occurs—meaning two devices transmit simultaneously—both re-sent their messages after a random delay. This experiment helped develop foundational principles for how modern wireless networks, like Wi-Fi and cellular systems, manage multiple users sharing the same frequency spectrum smoothly and reliably.
