In the world of IoT, energy efficiency is a critical factor that determines the success of a device. With the increasing number of IoT devices, it is important to choose the right generation of mobile communication technology that can support the device's requirements while maximizing energy efficiency.

In this presentation, we will explore the different generations of mobile communication technology and the protocols that are available for IoT devices. We will examine the pros and cons of each technology and highlight the key features that make them suitable for different types of IoT applications.

We will also discuss the optimal way to send messages in an energy-efficient manner, taking into account factors such as data rate, latency, and power consumption. By choosing the right combination of technology and protocol, IoT devices can achieve optimal energy efficiency and reliable communication.

The goal of this presentation is to educate IoT developers and decision-makers on the best practices for choosing the right generation of mobile communication and sending messages in an energy-efficient manner. By doing so, they can ensure that their IoT devices are reliable, cost-effective, and sustainable.
