Digital communication technology: The communication of digital signals transmitted by digital communications and transmitted by digital sources is a digital signal obtained through the source code of a digital terminal, and the digital signal emitted by the terminal is transformed into a digital signal suitable for transmission with the channel through channel coding. Then the modem modulates the signal to the digital channel used by the system and finally transmits it to the trust after the opposite transformation. According to the direction and time of information transmission, the data communication system has three types of simplex, semi-duplex, and all-purpose methods. Program-controlled exchange technology: Program-controlled exchange technology refers to the use of specialized computers to store pre-programmed programs into computers as needed to complete various exchanges in communications. The digital switches developed with program-controlled exchange technology are fast, small in size, large in capacity, flexible, and serve more functions, facilitating the change of switch functions, facilitating the construction of smart networks, and providing more and more convenient telephone services to users. It can also realize the exchange of fax, data, image communication, etc.. It is controlled by the program and is a telephone connection exchange device that is physically switched by the time division multiplexing network. Information transmission technology: one computer sends a fax to a remote computer or fax machine, one computer receives a fax sent by a remote computer or fax machine, screen conversations between two computers, and file transfers between two computers, That is, EDI(Electronic Data Exchange) technology. Communication network technology: A communication network is a communication system in which communication endpoints, node(junction) points, and transmission links are organically connected to each other to provide connection or non-connection transmission between two or more specified communication endpoints. According to different functions and uses, communication networks can generally be divided into three types: physical networks, business networks, and support management networks. Access technology: Access technology is one of the core parts of the modern telecommunication network system and has the role of connecting local end users and end users. The wire network structure is mainly composed of two parts, UNI(user network interface) and SNI(business node interface). The core network is the link connecting the user network interface and the business node interface. The main function of the access network is the effective connection of the communication information between the actual user and the terminal device. Compared with the fiber optic communication technology and Bluetooth technology, the access technology does not have the function of reuse and cross-connection. Bluetooth technology: With the more and more intelligent level of mobile phones, Bluetooth technology has gradually entered people's lives. Of all current communication technologies, Bluetooth technology can be said to be the latest communication technology. At present, mobile phones, laptops, wireless headphones and many other peripherals have Bluetooth capabilities. It can be said that the promotion of Bluetooth technology greatly simplifies the communication between terminal devices. Bluetooth technology also allows wireless devices to communicate with the Internet, and Bluetooth technology has another huge advantage in that users do not have to pay for the exchange of information using Bluetooth technology. In addition, Bluetooth technology does not require a fixed infrastructure, it is easier to install and the equipment is more adaptable.
