Question
What part of a packet radio frame contains the routing and handling information?
Answer Options
- A) Directory
- B) Preamble
- C) Header
- D) Trailer
Correct Answer: C
Explanation
Packet radio transmissions are broken down into discrete blocks of data called frames. Each frame is structured with different sections for control and data.
Similar to an internet data packet, the header of a packet radio frame contains all the necessary control information, including the call signs of the originating and destination stations, the data protocol identifier, and any routing or handling information required to send the frame across the network. The actual message content is contained in the data field that follows the header.
