1. Technical basis
4G module: The 4G module is based on LTE (Long Term Evolution) and provides relatively stable high-speed data transmission. It uses OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input Multiple Output) technologies to increase data transmission rate and reduce network latency. The design of 4G networks is mainly to meet the needs of mobile Internet, including streaming, video calls and large file downloads.
5G module: The 5G module introduces a new technical architecture, including millimeter wave bands, ultra-dense networks (UDN) and network slicing technology. The core of the 5G network is to significantly increase data transmission rate, reduce latency, and achieve higher connection density. 5G network architecture enables faster and more reliable communication between devices, supporting higher bandwidth and lower latency.
2. Performance comparison
Speed and bandwidth: The maximum download speed of 5G modules can reach 10Gbps, while the maximum speed of 4G modules is usually around 1Gbps. The bandwidth of 5G networks has been significantly improved, supporting more devices to connect simultaneously without affecting performance, which makes 5G have obvious advantages in high-speed data transmission and large-scale device access.
Latency: The latency of 4G networks is usually between 30-50 milliseconds, while 5G networks reduce latency to 1 millisecond or even lower. This ultra-low latency makes 5G perform better in real-time applications such as autonomous driving and telemedicine.
Connection density: 5G networks can support the connection of millions of devices per square kilometer, while 4G networks have a lower connection density. This makes 5G have greater potential in areas such as the Internet of Things (IoT) and smart cities.
3. Application scenarios
Application of 4G modules: 4G technology has been widely used in devices such as smartphones, tablets, and wireless hotspots. It is suitable for most daily Internet needs, such as video streaming, social media, and online games.
Application of 5G module: 5G module is not only suitable for traditional smart devices, but also extends to a wider range of fields. For example, applications such as self-driving cars, smart manufacturing, virtual reality (VR), and augmented reality (AR) all rely on the high speed and low latency of 5G. In addition, 5G also supports large-scale IoT applications such as smart city infrastructure and industrial automation systems.
