What type of data does packet radio primarily transmit?

Packet radio primarily transmits digital data packets, making it well-suited for a variety of applications that require efficient and error-checked communication. This method of transmitting data involves breaking information into packets, which can be sent independently over a network and reassembled at the destination. The advantages of packet radio include its ability to support multiple users simultaneously and its effectiveness in handling short bursts of data, which is ideal for digital communication systems.

Unlike audio signals, video streams, or analog signals, which require continuous transmission and can consume more bandwidth, digital data packets allow for more efficient use of network resources. They improve the reliability of data transfer through techniques like error detection and correction, making it a preferred choice in modern communication systems where data integrity and efficient use of bandwidth are critical.
