The Internet of Things (IoT) is transforming our world in countless ways, from the tiniest smart dust particles to the most sophisticated smart homes and factories. 

IoT continues to expand at a rapid rate; but standardising IoT devices is essential to ensuring smooth interoperability, strong security, and reliable performance. 

Design standards and protocols are crucial in creating an efficient IoT ecosystem of connected devices. 

Without these standards, we risk a fragmented IoT landscape where devices from different manufacturers struggle to communicate and work together effectively. 

Also, inconsistencies in communication protocols and security measures can lead to potential vulnerabilities and hinder the overall performance and reliability of IoT systems. 

Drawing on our work in the IoT space over the past decade or more at ByteSnap, we’ve created this comprehensive guide to give you a thorough overview of the various protocols and standards used in IoT product design.

Whether you are an IoT product designer, a business looking to integrate IoT solutions, or simply an technology enthusiast, use this handy guide as your connectivity concierge.

Table of Contents

As a highly experienced IoT product development team, at ByteSnap we’ve helped many companies define, refine, rescue, and rapidly engineer wireless device designs since 2008 and get them successfully to market. 

Over the years, we’ve dealt with many IoT development queries. We’ve answered some of them in the FAQs later in this guide.  For now, here are three common queries:

What’s the difference between IoT Protocols, IoT Standards, IoT Frameworks and IoT Architectures?

  • IoT Protocols are a set of rules and guidelines that govern the communication between IoT devices and systems. 

 

  • IoT Standards are guidelines that ensure interoperability, security, and privacy in IoT systems. 

 

  • IoT Frameworks are guidelines that define a common architecture and framework for the design, development, and operation of IoT systems. 

 

  • IoT Architectures provide a high-level view of the components and interactions of an IoT system, providing a blueprint for the design and development of IoT systems.

Why are IoT product design standards important?

Chiefly, IoT product design standards ensure interoperability between devices from different manufacturers. By adhering to a common standard, devices can communicate with each other seamlessly, reducing the need for proprietary communication protocols or gateways. 

This makes it easier for consumers to set up and manage their smart home or other IoT systems, as they can choose devices from different manufacturers that work together.

IoT product design standards also help to:

  1. Ensure the security and privacy of data transmitted between devices. Standards such as the Matter standard include several security features such as encryption, authentication, and device identity. This helps to ensure that data transmitted between devices is secure and private, reducing the risk of data breaches and cyberattacks.
  2.  
  3. Guarantee the reliability and scalability of IoT devices. Standards such as Zigbee or Bluetooth Mesh are designed to handle large-scale deployments of IoT devices, allowing them to communicate with each other efficiently and effectively.
  4.  
  5. Reduce costs for electronics product designers and manufacturers. By adhering to a common standard, manufacturers can reduce the need for custom development and testing, reducing costs and time-to-market for new products.
  6.  
  7. Drive innovation in the IoT industry. By providing a common framework for communication between devices, designers and manufacturers can focus on developing new and innovative products and services, rather than spending time developing custom communication protocols.

How do I choose the right IoT protocol for my project?

That will depend on several factors within your spec – such as the type of device, the data transfer rate, power consumption, and range requirements. 

It’s best to consult with IoT product design experts, such as ByteSnap, who can help you choose the right protocol for your development.

Ultimately, IoT product design standards are crucial for electronics product designers and manufacturers as they provide them with interoperability, security, reliability, and scalability.

By adhering to these standards, manufacturers can reduce costs, improve efficiency, and deliver better products to consumers.

Let’s now go through some key IoT product design standards and protocols.

IoT Product Design Standards

IoT standards are the guidelines and specifications that ensure interoperability and compatibility between different IoT devices.

The standards define the protocols, data formats, and security requirements that IoT devices must adhere to.

IEEE 802.15.4

This defines the physical and media access control (MAC) layers for low-rate wireless personal area networks (LR-WPANs).

IEEE 802.15.4 is used as the lower layer of Zigbee, Thread, WirelessHART, and 6LoWPAN networks and is well-suited for smart homes and building automation.

Zigbee

A wireless communication standard based on IEEE 802.15.4. It is designed for low-power and low-data-rate applications and is used in smart homes, industrial automation, and healthcare. 

Zigbee was the first widely adopted mesh networking system and, as such, has been perhaps the most successful IoT protocol for home automation systems after Wi-Fi. 

It also predominantly, but not exclusively, runs on the 2.4GHz, worldwide licence-free band. 

We have designed Zigbee products for many years at ByteSnap.  In fact, we developed the world’s first Zigbee metering module, the ZMM01, back in 2013.

Zigbee was extended in 2006 with the addition of a cluster library, which allows interoperability between different vendors’ devices that adhere to it. 

Zigbee was chosen, with the Smart Energy Profile, as the standard for UK smart meters that were SMETS2 compliant.

Thread

Thread has similarities with Zigbee. It too is a wireless communication standard that is based on IEEE 802.15.4 and also runs in the same frequency band. 

It was released in 2015, ten years after Zigbee. Thread is designed for low-power and secure mesh networking and is used in smart homes and commercial buildings. 

Thread builds up 6loWPAN to integrate IPv6 networking onto IEEE 802.15.4 which was seen as the main weakness of Zigbee as a bridge was always needed to interface Zigbee to the wider, IP-based, world (i.e., the internet!). 

Thread is a newer standard and presents some advantages over Zigbee as, to a large extent, it was developed on the shoulders of Zigbee; learning from mistakes made with Zigbee and fixing the main issue – the lack of native use of IP. 

However, it doesn’t define the full application layer that Zigbee does. Consequently, it doesn’t have the same inherent interoperability that Zigbee offers when products use the same clusters.

WirelessHART

WirelessHART is a wireless sensor network protocol that is commonly used in industrial applications.

It’s designed to provide reliable and secure communication between sensors and other devices in a plant or factory setting.

WirelessHART overview:  
  • Uses a mesh network topology, where each device acts as a repeater to extend the range of the network.
  •  
  • Operates in the 2.4 GHz frequency band and can support up to 100 devices per network.
  •  
  • Provides end-to-end encryption to secure data during transmission.
  •  
  • Has low power consumption, allowing devices to operate for years on a single battery.
  •  
  • Typical applications: Industrial sensors and monitoring devices, for example, temperature sensors, pressure sensors, and flow meters.

Wi-Fi

This wireless communication standard is commonly used in IoT products.

It provides high-speed data transfer and internet connectivity.
 
Key Features:

  • Uses a point-to-point network topology, where devices connect directly to a router or access point.
  •  
  • Operates in the 2.4 GHz and 5 GHz frequency bands and can support hundreds of devices per network.
  •  
  • Provides high-speed data transfer, with speeds up to several gigabits per second.
  •  
  • Has relatively high power consumption, which can be a challenge for battery-operated devices.
  •  
  • Typical applications: Smart home devices, such as thermostats, security cameras, and lighting systems.

SmartMesh

  •  

Bluetooth Low Energy (BLE)

BLE is a wireless communication standard for low-power and short-range applications. It is used in smart homes, healthcare, and location-based services. 

BLE is integrated into smartphone handsets and, therefore, has the big advantage over 802.11.4 protocols where a phone can directly interface with Bluetooth IoT devices, rather than requiring some form of bridge. 

This is, however, a weakness, as the Bluetooth bands can get clogged up in densely populated environments (e.g., schools, hospitals, airports, etc.).  

BLE is typically a point-to-point protocol, so the nodes have to be within range of each other to communicate rather than benefit from the hops that mesh networks provide. 

However, Bluetooth 5 has added a long-range mode (lower data rate) – and later Bluetooth Mesh – to address these issues. 

At the time of writing, Bluetooth Mesh has much lower adoption than Zigbee and Thread.

OneM2M

Machine-to-machine communication standard that provides a common framework for IoT devices to communicate with each other. It supports interoperability between different protocols and standards and is well-suited for large-scale IoT deployments.

ETSI EN 303 645

A standard developed by the European Telecommunications Standards Institute (ETSI) that provides guidelines for the cybersecurity of IoT devices It outlines requirements for the secure design and development of IoT devices, ensuring that they are resilient to cyberattacks.

Open Connectivity Foundation (OCF)

The Open Connectivity Foundation (OCF) is a standard that provides a common framework for IoT devices to communicate with each other. It supports interoperability between different protocols and standards and is well-suited for large-scale IoT deployments.

Matter Standard

The Matter standard, previously known as Project CHIP (Connected Home over IP), is a new open-source smart home standard developed to enable communication between different IoT devices.

Founded by the Connectivity Standards Alliance (CSA), the standard is supported by major companies such as Amazon, Apple, Google, and the Zigbee Alliance.

The Matter standard aims to provide a common language for IoT devices to communicate with each other, regardless of the manufacturer or communication protocol used.

The standard is based on IP and is designed to be secure, reliable, and scalable.

One of the key benefits of the Matter standard is interoperability. By using a common language, Matter-compatible devices can communicate with each other seamlessly, reducing the need for proprietary communication protocols or gateways.

This makes it easier for consumers to set up and manage their smart homes, as they can choose devices from different manufacturers that work together.

As Matter is adopted by more devices, it is likely to become an essential standard for the smart home industry.

The key point with Matter is that it sits on top of Thread, WiFi, or Zigbee; it doesn’t replace them. 


Other IoT standards and solutions by the CSA include:

Green Power

The Green Power IoT standard is designed to provide a low-power, energy-efficient solution for IoT devices. 

This standard enables IoT devices to operate using energy harvested from their surroundings, such as light, motion, or temperature changes. By using energy harvesting technology, IoT devices can operate for extended periods of time without the need for battery replacement or recharging.

 

Smart Energy
