In general, CDMA is a channel access method that helps various terminals transmit over the same infrastructure. This is a type of multiplexing that accommodates different data streams over the same channel or communication medium.

With B-CDMA, engineers expand the bandwidth of CDMA waveforms where signals share a band of frequencies. All of these aid in the process of creating efficient signaling systems for wireless networks. This type of construction can be found in different structures like bus networks, ring networks and different kinds of point-to-point networks.
