5G, or the fifth-generation mobile phone action communication standard, has become a hot topic in recent years in the technology field. Compared to 4G, 5G technology offers higher speeds, lower latency, and greater capacity. Here are the main features of 5G networks: 1. Extreme speed: The theoretical maximum download speed of a 5G network can reach up to 10 Gbps, more than ten times faster than a 4G network. 2. Low latency: The low latency of a 5G network makes it ideal for applications that require real-time interaction, such as autonomous driving and remote medical treatment. 3. Large capacity: 5G networks have a larger bandwidth and capacity, allowing for the simultaneous transmission of more data. 4. IoT support: 5G networks provide strong support for the development of the Internet of Things (IoT), meeting the needs of more devices to connect to the Internet simultaneously. 5. Slicing technology: 5G networks support network slicing technology, allowing customized network services to be provided according to different business needs. **III. Conclusion** Overall, both 4G and 5G are crucial
