Application of wireless network technology in the oral English teaching under the background of 5G mobile communication

5G mobile communication is a digital mobile network in which analog signals of audio and images are digitized through the PE terminal, and then converted to digital through an analog converter and used as a bit stream transmission. The communication is carried out through the local receiving device and the low-power automatic transceiver. In order to carry out comprehensive resource sharing and organic collaboration, we integrate wireless network technology and distributed resources on the Internet into a huge whole, so that everyone can use the resources. Wireless network technology can be used to build company and organization internal networks, local area networks, system local area networks, and home and personal networks. If 5G mobile communication wireless network technology is used in spoken English, then spoken English will have a better development. Spoken English is a form of oral communication and is commonly used in English-speaking countries. Oral English is usually communicated through mouth and lip shape and tone, Can flexibly use spoken English for dialogue in different situations and between speakers. The oral teaching system is an important activity system for teachers and students to work together to achieve educational goals. It is composed of teacher and student education information, textbooks and equipment platforms. It is controlled by three different systems, namely execution, feedback and control systems. Contrary to spoken language, written English is a language developed based on spoken language for written expression.
