There was such a dispute associated with cellular networks.

As far as I understand the principle of operation of cellular networks, the connectivity of one subscriber with another is as follows:
My phone communicates with the BS. BS communicates with the interlocutor through a series of other BS, so, as I understand it, these networks are called cellular.

My opponent argues that the relationship is as follows:
My phone is associated with BS, BS with the satellite, the satellite BS of the interlocutor, and the interlocutor of BS with the phone of the interlocutor.

Prompt, please, who is right?

Typically, the optical channel from the BS. Can be radio, satellite, true, you say. But the scheme is slightly different:
телефон1 --> BS --> [optics/radio/partner] --> switch operator --> [optics/radio/partner] --> BS --> телефон2

Networks are called cellular, because bees like to live close to the BS and they often build hives, placing the honeycomb on the equipment. The rampant prevalence of this amazing behavior of bees and has led to the adhesion of the name "cellular". It is unclear what causes the inaccessibility to humans, some special electro-magnetic radiation or something.

It is, between the BS there is a radio connection at a frequency of tens of gigahertz. With its help BS form a network. Large semicircular antenna at BS for her intended. Although perhaps a satellite link somewhere in rare cases and used.
