Top 13 IoT Protocols You Should Consider for Product Development

  • July 11, 2025

Introduction

The fast growth of the Internet of Things (IoT) has changed the way devices connect and share data in many industries. As more and more devices get connected, choosing the right communication protocols becomes very important. These protocols affect growth and security of the system.

Choosing the right IoT protocol is important when building a product because each one serves a different purpose—from saving power in small sensors to handling large data in factories. Knowing how these protocols work helps developers create, deploy and maintain strong and future-ready IoT devices.
