The difference between 4G and 5G networks lies primarily in speed, latency, and capacity. 5G networks offer significantly faster download and upload speeds, theoretically reaching up to 10 Gbps, compared to 4G's maximum of around 1 Gbps. Additionally, 5G exhibits lower latency, allowing for real-time communication and responsiveness, which is crucial for applications like autonomous vehicles and augmented reality. Furthermore, 5G can support a larger number of devices simultaneously, enhancing connectivity in crowded areas. This evolution enables new technologies and applications, driving forward a more connected world.
