In the modern world, mobile communications are of great importance. Many businessmen conduct business negotiations using mobile communications, which have become an integral part of the life of not only a businessman, but also an ordinary person.
Since its inception, not only the telephone, but also mobile communications have been constantly improved. A modern smartphone 폰테크 or iPhone can replace a full-fledged gadget and be used not only for conversations, but also for video communications.
Let’s consider the milestones in the development of modern telephone technologies:
- 1G wireless telephone technology. This type of telephony allowed subscribers to exchange voice messages;
- 2G is a secure digital communication with encryption. This format allowed subscribers to communicate via text messages and pictures;
- 3G – this type of telephony was able to combine several functions: text and voice messages, video communication and Internet access. The main principle of operation is packet data transfer;
- 4G – this type of communication, like the previous one, is based on packet protocols. It provides subscribers not only with high-speed Internet access, but also the ability to exchange various types of information.
Currently, 5G mobile communications are being developed, initiated by the Chinese brand Huawei.
