Quizplus · Accepted Answer

The first generation of wireless cellular telephony used analog circuit-switch technology to transmit data at a speed of 9.6 Kbps. Circuit-switching involves establishing a dedicated and direct connection between two devices for the duration of the call or data transfer, which was the primary mode of operation for early cellular networks. Packet-switching and frame-switching technologies were not introduced until later generations of wireless cellular technology. Unit-switching is not a recognized term in the context of networking technology.
