When did the BB machine appear? Who used it?

BP(BB) machine, also called pager, is used to be called BB machine because it emits BB sound when receiving information.

1983, the first paging station was built in Chinese mainland. In the early 1990s, paging stations sprang up like mushrooms after rain, including social stations in the post and telecommunications system and paging stations at 126 and 127. 1998, the paging business was separated from the post and telecommunications system, and Guo Xin paging company was established, which was still affiliated to the post and telecommunications system at that time. In the end, posts and telecommunications were separated from telecommunications, and telecommunications were separated from mobile. This is another matter.

Pagers are divided into digital machines and Chinese machines. Digital machines can only receive numbers. Numbers have corresponding codes, and each code represents different content. For example, the received code is 203, which means please call back. Because of this, someone was wearing a digital BP machine around his waist, and at the same time, the BP machine also carried a code correspondence table. Later, Chinese BP machine appeared, and the received text content was sent by manual station.

Each paging station is generally divided into automatic station and manual station. An automatic station means that you dial the paging station number by telephone, such as the pager number of 127+, and there will be a prompt tone after the connection. You can send digital information through the number keys on the phone. As long as the information receiver knows the meaning, this digital information can be customized without following the standard code. When using the automatic paging station, you can also hang up after hearing the prompt tone. The received BP will display the phone number of the page, and the information receiver can answer the phone by phone or mobile phone. The manual station assists the pager to send digital or Chinese information to the received BP machine through the reception of the manual seat.

In the era when mobile phones were not popular, BP machine was an important and main communication tool at that time, which played a huge role in people's work, life and social interaction. Some people even have several sets, both digital and Chinese. There was a BP machine at that time, which was also worth showing off. The brands of BP machine mainly include Motorola, NEC and Panasonic. Of course, there are many domestic brands. In the later period, the BP machine was a little messy, and even the family workshop could produce the BP machine, but the quality was poor. The price dropped from 1000 yuan for digital BP machines to several hundred yuan, or even one or two hundred yuan. Of course, opportunities in China are very expensive, and ordinary family workshops have no technical ability to produce.

Here, I would also like to say that the earliest digital pagers had no time, and they could only ring without shaking. Before that, they not only had time and vibration, but also had the function of alarm clock, which could adjust several sounds to receive information.

With the improvement of people's living standards and the development of communication, the BP machine, like a roller coaster, has exploded from one machine to the peak, and then declined rapidly, especially with the technical progress and popularization of mobile phones. In the mid-1990s, it began to decline. A large number of users lost their jobs and turned to mobile phones as the main communication tool. Social paging stations closed down first or in large numbers. Until 2005, the paging station basically completed its historical mission and withdrew from the stage. Due to different local conditions, BP machines will withdraw from the market sooner or later. As the state-owned Guo Xin paging company at that time, it was merged into China Unicom on May 1999. From a single paging service, it has also turned to mainly develop mobile communication services. As a communication tool, the inconvenience and limitation of pager has gradually been completely replaced by mobile phone.

I don't know when it appeared, but I know when it disappeared. At 200 1, my classmate brought an unused bb machine to tell the time. I happened to see 200111111.
