The term broadband network has two completely different meanings. On the one hand, it refers to networks that use carrier-modulated technology on one or two cables (single- or dual-cable broadband networks).
The signals are transmitted in individual frequency channels. For this purpose, the signals must be modulated onto the different carrier frequencies.IEEE 802.3 10Broad-36.
In addition, a broadband network is understood to be a high-speed network with a data rate that is above the primary multiplex rate of 2.048 Mbit/s (Europe).
