Japan's last BB machine company stopped serving. Which countries still use BB machines?

With the appearance of mobile phones, BB has gradually withdrawn from the historical stage. At present, only a few countries are using it, but there are still some backward and poor countries using it. For example, in some poor African countries, BB machines have become a hot item. Because these countries are backward in communication, backward in social development, and generally poor, they simply can't afford to buy newer products such as mobile phones, while BB phones are cheap, less disturbed, strong in signal and save electricity, which have become popular products in these countries.

With the popularity of mobile phones and the rapid development of modern technology, BB has been abandoned by most countries. But it is unexpected that 85% of hospitals in the United States still use BB machines for communication, and every doctor is hung with a BB machine, waiting to be paged. Is this the backwardness of the United States? Let's take a look, mainly because the biggest difference between a mobile phone and a BB machine is that the mobile phone itself is a radiation source. In some radiation-proof areas of hospitals, mobile phone signals can't be received at all.

In order to be able to search for signals, mobile phones have become a powerful radiation source and an interference source, which can interfere with sophisticated medical equipment, make these sophisticated equipment work abnormally and send out wrong signals. In order to prevent this from happening. You can use the BB machine. Because the BB machine works in VHF band, it has strong diffraction ability, wide signal coverage and low transmission power. It can realize reliable transmission, the transmitted information is short and the cost is low, which makes these hospitals insist on using it. In addition, many walls in the hospital have been treated with radiation protection, and the cell phone signal can't be received at all, forming a lot of dead ends without signal, because BB machines can communicate directly with each other through internal signal forwarding devices, that is, there is no need for external base stations.

Another reason is that doctors have a clear distinction between public and private interests. When they go to work, they turn on their mobile phones and use BB to communicate in hospitals. Hospitals have paging desks, so it is very convenient to find doctors during working hours, and work and life are strictly separated. When they go home from work, they use their mobile phones, while when they go to work, they have a clear distinction between public and private interests, which can better balance work and family.
