Page "Channel (communications)" Paragraph 69

* A point-to-multipoint channel, also known as broadcasting medium ( not to be confused with broadcasting channel ): In this channel, a single sender transmits multiple messages to different destination nodes.

All wireless channels except radio links can be considered as broadcasting media, but may not always provide broadcasting service.

The downlink of a cellular system can be considered as a point-to-multipoint channel, if only one cell is considered and inter-cell co-channel interference is neglected.

However, the communication service of a phone call is unicasting.
