The Complete Guide to IoT Standards and Protocols

What is an IoT Standard?

The IoT standard is a communication protocol that helps in connecting devices and machines to the internet.

The IoT standard is created by a group of companies that strive to make a standard for the Internet of Things. The standard has been developed in order to help in facilitating and improving the connection between devices and machines.

The IoT standards are an open-source platform where all interested parties can contribute and create their own standards for the internet of things.

What does an IoT Standard and a Protocol Actually do?

The Internet of Things (IoT) is a network that connects physical objects and devices to the internet.

To help us understand what an IoT standard and protocol actually do, let’s take a look at the following example.

Imagine that you are a company who needs to design an IoT device. You want your device to connect with other devices in your company, but unfortunately you don’t have any experience in this area. To make things easier for you, you decide to use an IoT standard or protocol – like Wi-Fi or Bluetooth – that will help you connect to other devices without needing any knowledge of how they work.

An IoT standard is a set of rules and guidelines used by manufacturers when creating their products so that they can be compatible with other similar products on the market. An IoT standard would also mean that a product could communicate with other products simultaneously without any technical incompatibilities. One of the most popular standards in IoT is IEEE 802.15.4, which is a wireless protocol for connecting low-power, low-cost devices to networks and each other over short distances (typically 10 meters). This standard can be used for IoT device.

What are the Different Levels of IoT Protocols & Standards from Low to High?

The internet of things is a term that describes the connection of everyday objects to the internet. There are many protocols and standards that are used to connect these objects. Some of these protocols and standards are low-level while others are high-level.

Low Level: Low level protocols allow devices to communicate with each other without any human interaction. The devices may use radio frequency or infrared light signals to transmit data. Low level protocol is suitable for small scale networks where not much is required from the devices.

High Level: High-level protocol uses a lot of data transmission, which means it can be used on larger scale networks that require more data transmission for various applications such as industrial automation, remote monitoring, and medical care systems.

Advantages of IoT Standards and protocols

IoT standards and protocols have the potential to change the way we interact with technology in various aspects. They can be used to simplify our lives and make it easier for us to communicate.

The following are some of the advantages of IoT standards and protocols:

  • They can provide a more efficient way of communication between devices;
  • They can help in achieving efficiency, cost savings, and improved performance;
  • They can also help in making a better quality product by providing greater control over product design;
  • They can provide greater security for data by allowing only authorized devices to access it.

What’s the difference between protocols and standards?

Protocols are the rules and standards are the implementation of those rules. Protocols are the set of guidelines followed by a group of people or a society. Standards on the other hand define how something is supposed to be done.


  • The rules and guidelines followed by a group of people or society
  • Examples: The protocols for how to respond in an emergency situation, how to behave at a funeral, what constitutes as harassment, etc.

A protocol can be either written or unwritten


  • How something is supposed to be done
  • Examples: Standard for driving on the road, standard for business attire, standard for using social media responsibly

The four essential IoT standards and protocols.

The IoT is the next big thing in technology. It has already been around for a while but it is getting more and more popular. The IoT consists of devices that are connected to the internet, such as smart home appliances, sensors, etc.

The four essential IoT standards and protocols are:

  1. WiFi: Wi-Fi, is a wireless local area network technology that uses radio waves to provide a wire-free and convenient way to connect devices to the internet. WiFi is used in many devices from smart phones, tablets, laptops and computers.
  2. Zigbee: Zigbee is a low power radio frequency that has been in use since 1998. It has been used in a variety of applications and is known for its ability to communicate with devices without need for line-of-sight.
  3. Bluetooth: Bluetooth, or short-range radio signals, is a wireless technology that has been rapidly spreading across the world. It uses a small device to transmit data such as sound, photos or videos wirelessly. Bluetooth is easy to install and can easily connect up to 8 different devices.
  4. Z-Wave: Z-Wave is a wireless standard that uses long range radio signals to communicate between devices. It has a longer range than WiFi and Z-Wave technology is used in hundreds of thousands of product installations worldwide, including smart homes.
