A radio network consists of two or more radio stations operating on the same frequency for the purpose of communicating with one another. Radio transmissions are one-way (Simplex) communications, which means only one person can transmit at a time. If two or more users transmit at the same time, they will cancel each other out and no sound will broadcast. In order for a network to function properly, all the network users must follow basic standard radio procedures. Failure to follow these standards will render communication between users difficult or impossible.
Radio networks are controlled and administered by a Net Leader. This person is responsible for directing network traffic, performing radio checks, and ensuring the security of the network. The Net Leader also establishes which channel(s) the network will use for transmission and the call protocols of its radio stations (users). The Net Leader for the Mrak Hall Net is the Building Coordinator .
