Mobile phone 1961 (90s, USSR, origin, years)

[ukrkoz]

I think it will be interesting read.

This device:


Weighed 70 grams. Had two transmitters and one receiver. NiCad batteries provided up to 30 hrs of use time.
It was final development in 1961. yes, 1961, 12 years before Motorola Martin Cooper used his mobile phone in Manhattan.
Development was result of work of one engineer Mr Kupriyanovich, in then USSR. His first portable phone was designed and used in 1957. That's Kupriyanovich in the streets of Moscow in 1957 dialing.

You can see much later first mobile phone per comparison in the right hand photo.
This is 1958 model, somewhere on a boat:

Range was around 30km and had to utilize a translator station, that was developed for this type of communication.

1961 model was patented and approved for mass production. Why it didn't happen is everyone's guess.

Bandwidth was a huge issue before digital transmissions. Only certain frequencies are allowed for voice communication, and even with SSB (single side band) there wouldn't have been enough room on the spectrum for phones using analog.

I remember doing a lot of work with one of the Baby Bells. There was one old veteran who told me, in the early 90s, how mobile phone technology was prohibitively expense would never eclipse landlines. Five years later, he's calling me up begging for job leads.

The lesson I derived from that? When some old guy in an industry tells me why something won't fly, I know it's only a matter of time before it will.

Are these radio-telephones?
Using radio wave transmissions that can link with a phone network?

Motorola and Bell Labs had these out in 1946
