"Net Operations, or a Controlled Net, is a system for coordinating communication among groups of four or more people" (CERT Emergency Communications, 2012, p. 28).

• Small teams communicating among themselves use standard radio protocol.
• When teams connect with other teams they need to contact a Net Control operator
• A controlled net has one or more Net Control Operators. 
• The net control operator will direct a call with whoever you need to speak.
• The net control operator may direct you to stand-by or direct you to another channel.
• Calls are prioritized in the net operations by the nature of the message.
