ALOHA Channels

ALOHA channels are a type of wireless communication system designed for sharing a common frequency among multiple users. Originating from early satellite and radio network technologies, ALOHA uses a simple method where users transmit data whenever they want. If two users send data simultaneously, their messages collide, causing errors. The system detects these collisions and retries occur after random intervals. This approach allows for flexible and efficient use of the available spectrum, especially in environments with unpredictable or low traffic. ALOHA channels laid the foundation for more advanced protocols used in modern wireless communication.
