The first mobile phone was introduced by Motorola. And the first person who spoke on a mobile connection was her employee - Martin Cooper. In 1983, he called his competitors and said that he was standing in the middle of a New York street talking on a cell phone. In those years, it was an innovation on the verge of fantasy.
The first smartphone appeared in 1993, but it looked a little like modern smartphones: it had a calendar, email, address book and other simple functions. But the screen was made big. The price was also rather big - from $ 900. And people paid, because many wanted such a technical novelty.
Smartphones of that time had buttons, but the keypad was not invented right away. Therefore, it so happened that the phone, lying in his pocket, called someone "himself" - purely by chance, and the one who answered the phone heard only interference. The police received such calls often: according to the statistics of the American 911 service, there were 70% of them, so the police of those years even got used to it and did not pay attention.
And the best-selling mobile phone brand in those years was Nokia 1100, which was considered the most compact, functional and inexpensive. It appeared on the shelves in 2003, and 250 million people bought such a model. At that time no one thought about Apple as a popular brand of mobile devices.
And the first phone with 2 SIM cards was Samsung Duos, which made business people very happy. Indeed, before the appearance of this model, they had to carry several mobile devices.
There are tons of interesting facts about phones, but the top 10 includes the following:
- Friedhelm Hilbrand not only created SMS, but also introduced a limit on the number of characters in a message. Now there is no such limit, but before it was equal to 160 characters. This is 2 lines, which, according to Hilbrand, was enough to send a short note. All well-known operators agreed with him, and in 1986 the character limit became official.
- Without mobile towers, phones are useless, and towers are set up everywhere. But they don't catch the eye, because they try to hide them from people: on poles, on the roofs of buildings, even in city clocks. And in America, mobile towers are disguised as trees or cacti.
- With the proliferation of mobile devices, people have new phobias. Those who are afraid to call or answer calls suffer from "telephonophobia", and those who are afraid to be in a place without communication or lose their phone - "nomophobia". There are people who panic at the thought that they can get sick with something terrible if they use mobile communications - this is a symptom of "Frigensophobia".
- According to statistics, there are about 3.3 billion working mobile phones in the world - and this is half the size of the entire population of the Earth. And since not everyone uses the devices - more often adults and active people - there will be about 158 working communication devices per 100 people.
- People change their mobile phones often, in the same Korea - every 11 months. And it's usually not that the device has broken, it's just that a person wants a new model. The old one is sent to the trash can. When you consider the number of these discarded phones and their half-lives, one can imagine the enormous scale of their pollution.
- Scientists want to use mobile devices as anti-terrorism sensors. For this, models are being developed that can detect the presence of radioactive materials in the vicinity of a person. And it makes sense, because terrorists are more likely to attack city centers - places where there are a lot of people, and people have phones with them. If the idea of scientists from Purdue University succeeds, it will help prevent terrorist attacks.
- The most expensive mobile phone in the world is considered the iPhone 4 Diamond Rose, which functionally does not differ from the regular iPhone 4. But the body of this phone is made of gold and decorated with diamonds, and it is handmade. And its price is $ 8 million.
- The term "cell phone" in English looks like "cell phone". It arose because the coverage areas of base stations are divided into cells - "cell", and for the first time this term was used in 1977.
- In Japan, most mobile phones are waterproof because teenagers use them even in the shower.
- In Mexico, drug cartels steal engineers and force them to work to build a private telephone network.
