Phone generations

Early Generation Zero Generation

0G Radio telephones (1946)
Mobile Telephone Service (MTS) was a pre-cellular VHF radio system

Which linked to Public Switched Telephone Network (PSTN).

MTS was the radiotelephone equivalent of land dial phone service.

Upgrade time


Improved Mobile Telephone Service (IMTS). IMTS  Introduced in 1964, it replaced Mobile Telephone Service (MTS) improved on MTS systems

Difference
by offering direct-dial rather than connections through a live operator,
and full-duplex operation so both parties could talk at the same time.

Capable of interfering with peoples immune system after having a convo with a friend of same mind about RF signals, we both come to con conclusion there is interference to people.

 So 5G is a bunch of old tech just being updated with more crap. And actually causing a problem with people, lots of miss information's flying around.
