1, wireless network
Wi-Fi technology is one of the most common and widely used wireless access technologies. It transmits data through wireless signals, enabling devices to wirelessly connect to a local area network or the Internet, and provides the functions of wireless Internet access and local area network connection.
2.4G LTE (4th Generation Long Term Evolution)
4G LTE is a high-speed mobile communication technology, which provides faster data transmission speed and lower delay. Support high-definition video streaming, online games and other applications, suitable for smart phones, tablet computers, mobile routers and other mobile communication devices.
3.5G (Fifth Generation Mobile Communication)
5G is the latest generation of mobile communication technology, which is famous for its ultra-high speed, low delay and the ability to connect more devices. The 5G network will provide faster download and upload speed, support more smart devices and Internet of Things connections, and have broad application prospects.
4. Bluetooth (Bluetooth)
Bluetooth technology is a short-distance wireless communication technology, which is used for data transmission between devices. It is mainly used to connect personal devices such as wireless headphones, stereos, keyboards and mice with smart home devices.
5. Near field communication
NFC technology is a short-range wireless communication technology, which is used for near-field data transmission between devices. Widely used in mobile payment, identity recognition, intelligent door locks and other fields.
In wireless access technology, why does 5G technology have broad application prospects?
The reason why 5G technology has broad application prospects is mainly based on the following characteristics and advantages:
1, faster.
Compared with the previous communication technology, the 5G network has a higher transmission speed. Its data transmission rate can reach dozens or even hundreds of times that of 4G, which realizes ultra-high-speed data transmission and can support faster download and upload speed.
2. Lower latency
5G technology has achieved lower transmission delay, reducing the delay to millisecond level. This is very important for real-time interactive applications, such as autonomous driving, telemedicine, virtual reality and so on. Can provide a more stable and smooth user experience.
3. More connected devices
5G technology can support more devices to connect at the same time. This is very important for the application of Internet of Things (IoT), which can connect and manage a large number of smart devices and promote the development of IoT.
