Abstract: “The enhancement of environmental connection of things through the internet is based on the efficiency of the cellular network and how much it can serve massive amount of devices. The roll of previous cellular network s in the Inter net of Things (IoT) trend ser ves a small number of devices with limited data rates, insufficient delay and large percentage of packet loss. In this research the aim is to measure the efficiency of a real test of an IoT environment using 3G and 4G cellular network sequentially, and als o testing the same network in a simulative environment and compare the outputs to the real test outputs measuring the accuracy of the simulation, then also to examine a 5G network based on the millimeter wave (mmWave) and directional antennas, from this po int we can analyze the efficiency of the 5G network based on the accuracy of the simulation. Bottom line, we have achieved an overall enhancement percentage of the throughput 84% and lessened delay by 80%, but, the number of”
