Which of the following is a category of radio nets?

• A. Simple net
• B. Broadcast net
• C. Mesh net
• D. Shared net

Answer: (A)

Nets are categorized by how stations connect and pass traffic. The simplest form is a simple net, where all stations monitor the same frequency and can communicate with each other directly, often with a net control station to manage who talks when. This basic, one-frequency, all-on-one-level setup is the foundational category of radio nets. The other terms describe more specialized arrangements: a broadcast net centers on one transmitter sending to many receivers, a mesh net involves multiple interconnections where messages can be relayed through multiple paths, and a shared net is an arrangement where several groups use the same net resources. Because the question asks for a general category, the simple net fits best.
