What were the first cell phones?

It is difficult to find today a man who does not have a mobile phone. It is used even by children who have barely learned to press buttons. For those of the little ones who still do not know the numbers, the parents set everything on the “automatic” and showed which button the father and the mother use. It remains only to press. Clay cell phones come across even in archaeological sites. But this, of course, is a hoax

Our life simply cannot be imagined without a mobile phone. And many even have two. These devices themselves are becoming smaller and smaller in size and weight. Microphones appeared embedded in a wrist electronic watch. In this case, the watch itself is used for its intended purpose. In a word, progress continues. But some three decades ago in society and did not know such words – “cellular (mobile) communication”.

Although even then there was a tendency to eliminate wired communications and go on the air. It was not about personal wearable radio stations operating in the VHF band, but about devices operating autonomously at completely different frequencies and with completely different principles of signal transmission and reception through the network (cell) of a number of towers.

Although a modern cell phone “came” to our country through the West, it is a mistake to assume that it was invented there. In 1957, the Soviet radio designer L. Kupriyanovich assembled an experimental mobile phone. L. Kupriyanovich demonstrates his radiotelephones

It was a device with a pretty decent weight (3 kg). The following year, the weight of the device was reduced to 500 grams – mainly due to more compact parts and the use of plastic. In 1961, L. Kupriyanovich demonstrated a pocket phone. But its introduction into the series has stalled – post-war economic difficulties affected the USSR, and the orientation remained on cheaper wired phones.

The situation was almost the same in other countries. The serial mobile phone appeared on sale only in 1973 – Motorola DynaTAC. And he was significantly heavier than the Soviet one (weighed more than a kilogram), poorly “held” in his hand because of his large size. Nevertheless, it was an industrial assembly device that immediately showed great prospects for the development of communications. The first mobile phones made it possible to communicate on air over a short distance and had a very weak battery (it lasted only for one hour). But the main drawback was that it was necessary to first call the base station and dictate the number of the subscriber with whom the connection was already from the station.

In addition, the so-called receive-transmit button was used, which complicated the conversation. Carrying a “box” with an antenna was not very comfortable. Yes, and the high cost of a scarecrow mobile phone. In the USSR, cellular communications were hardly used until the mid-80s of the last century. With a vast territory, coverage with this type of communication was very small. However, I remembered the chip of that time: the “new Russian” in a crimson jacket and with a “pipe” in his hand – a Mobira-MD 59 NB2 telephone. This device weighed 3 kg. For the connection, the provider took four thousand dollars. A minute of conversation cost one American dollar. But already in 2003, according to providers, in Russia there were 30 million mobile phone users. How many of them are now – no one can say, because the situation is approximately the same as during the boom with pocket transistor receivers.
