5g and 4g architecture

This document provides an overview of 4G and 5G architecture and their key differences. 4G uses technologies like LTE-A and WiMAX with data rates up to 3Gbps download and 1.6Mbps upload, operating in frequency bands between 1.8-2.6GHz. 5G is expected to have significantly higher data rates up to 10-50Gbps using technologies like BDMA and new frequency bands up to 300GHz to enable applications requiring low latency like VR. 5G aims to address limitations of 4G like higher capacity to support more users and IoT devices, as well as lower latency critical for applications like autonomous driving.
