Question

Quizplus · Accepted Answer

The first generation of mobile communication technologies, such as the analog-based AMPS (Advanced Mobile Phone Service) and NMT (Nordic Mobile Telephone), used circuit switching. This means that a dedicated circuit was established between the caller and the receiver for the duration of the call, tying up the network resources until the call was finished. This was inefficient and limited the capacity of the network.
