Currently, the commonly used wireless access technologies are mainly the following:
1, Wi-Fi (Wireless LAN)
Wi-Fi technology is one of the most common and widely used wireless access technologies. It transmits data through wireless signals to enable devices to wirelessly connect to a LAN or the Internet, providing wireless Internet access and LAN connectivity.
2. 4G LTE (Fourth Generation Long Term Evolution)
4G LTE is a high-speed mobile communication technology that provides faster data transfer speeds and lower latency. It supports applications such as high-definition video streaming, online gaming, and is suitable for mobile communication devices such as smartphones, tablets, and mobile routers.
3. 5G (Fifth Generation Mobile)
5G is the latest generation of mobile communications technology, known for its ultra-high speeds, low latency and the ability to connect more devices.5G networks will offer faster download and upload speeds, support more smart devices and IoT connectivity, and have a wide range of applications.
4, Bluetooth (Bluetooth)
Bluetooth technology is a short-range wireless communication technology used for data transmission between devices. It is mainly used for wireless headphones, stereos, keyboards, mice, and other personal devices and smart home devices to connect.
5, NFC (Near Field Communication)
NFC technology is a short-range wireless communication technology for near-field data transmission between devices. It is widely used in mobile payment, identification, smart door locks and other fields.
Why does 5G technology have a broad application prospect among wireless access technologies?
5G technology has a broad application prospect, mainly based on the following characteristics and advantages:
1, higher speed
5G network compared to the previous communication technology, has a higher transmission speed. Its data transfer rate can reach dozens or even hundreds of times that of 4G, realizing ultra-high-speed data transmission that can support faster download and upload speeds.
2. Lower Latency
5G technology realizes lower transmission latency, reducing latency to the millisecond level. This is important for applications with high real-time interactivity, such as autonomous driving, telemedicine, and virtual reality, to provide a more stable and smooth user experience.
3. More connected devices
5G technology is able to support more simultaneously connected devices. This is critical for Internet of Things (IoT) applications, which can connect and manage a large number of smart devices, driving the growth of IoT.
