Review Questions
How does 5G improve upon the previous generations of mobile networks in terms of speed and latency?
5G improves significantly over previous generations like 4G by providing speeds that can reach up to 10 Gbps, which is around 100 times faster than 4G. This increased speed allows for quicker downloads, smoother streaming experiences, and more reliable connections for a greater number of users. Additionally, 5G offers latency as low as 1 millisecond, which is crucial for applications requiring immediate responsiveness such as online gaming or remote control of devices.
In what ways does the layered network architecture of 5G contribute to its capabilities and performance?
The layered network architecture of 5G is designed to manage different types of services efficiently. By using techniques like network slicing, which creates virtual networks tailored for specific applications or user groups, 5G can optimize resource allocation and enhance overall performance. This flexibility allows 5G to support a diverse range of services—from high-speed mobile broadband to critical IoT applications—each requiring different levels of bandwidth, reliability, and latency.
