How to Choose the Best IoT Module for Your IoT Project

What is IoT Module?


The Internet of Things (IoT) has the potential to revolutionize the way we interact with the world around us. From regulating the temperature of our refrigerators to tracking packages and livestock, providing faster security and monitoring, and enabling smart grids for entire cities, IoT brings intelligent transformation for both personal and industrial purposes. It holds significant value in terms of providing greater convenience, higher efficiency, improved work quality, and better utilization of big data. Digital transformation has become crucial for business growth, societal development, and economic expansion, with IoT at the core of this transformation.


The number of IoT device connections is expected to continue growing in the coming years. According to a report by IoT Analytics, the global number of active IoT endpoints reached 14.3 billion in 2022. IoT Analytics predicts that by 2023, the global number of connected IoT devices will grow by another 16% to reach 16.7 billion active endpoints.



IoT modules, small computing devices that allow physical objects to connect to wireless networks, are one of the most critical components in any IoT deployment. These foundational building blocks continuously sense, collect, store, and transmit data to enable wireless communication between devices and networks, making them a vital part of IoT solutions. However, with numerous module solutions and vendors available in the market, choosing the best module product becomes essential for successful IoT deployments.



How to Select the Right IoT Module?


Understanding Your Project


Before selecting the right module, it is important to understand the following aspects of your project:


  • The scale and scope of your project
  • The anticipated power consumption of your project
  • The environment in which you will deploy the connected devices
  • The range, data volume, and accuracy required for your project
  • Hardware and software inventory, including your company’s network setup



What are the Parameter Filters for Module Search?


Manufacturers typically list modules based on various parameters, including the radio frequencies they operate on, data rates (such as bytes per second), range, and certifications. Therefore, filtering your IoT module search based on parameters that meet your specific IoT requirements is crucial.


Here are some of the most important parameters to consider:


  • Mobile communication network standards and frequency band configurations:

Network standards refer to the type of network. Mobile communication relies on radio waves, and to efficiently utilize spectrum resources, radio frequencies are divided into different bands, like lanes on a road, for different communication standards to travel on their designated lanes. In order to facilitate communication, each frequency Band that has been divided is also replaced by band plus numbers or direct B plus numbers.


The combination of network standards and frequency bands forms the networks that a module product can support. If a product supports all network standards and frequency bands in a specific country or region, it is considered a global product for that area, allowing seamless connectivity within the mobile network coverage area.


  • Interfaces:

Communication interface technology is crucial in IoT systems, including interconnecting various communication networks, enabling various terminal devices to connect to the network, and adapting to different communication protocols and software.


Depending on the actual scenarios involved in IoT communication, IoT communication interface types can be divided into several categories. The first two categories involve long-distance wireless communication based on cellular communication technologies such as 2G, 3G, 4G, 5G and NB-IoT, as well as non-cellular long-range wireless communication methods such as Lora and Sigfox. The third category includes short-distance wireless communication technologies such as Bluetooth, UWB, NFC, RFID, WiFi, and Zigbee. The fourth category covers wired communication, including various serial communication interfaces such as USB, RS485, RS232, RS422, Ethernet, and MBus communication methods.


  • Wi-Fi protocol support:

 IEEE 802.11 represents the most commonly used series of wireless LAN standards worldwide. Today, there are many 802.11 series standards in use, each with its own specifications. When selecting these protocols, three key factors need to be considered: data rate, range, and power requirements. Protocols like 802.11n, 802.11ac, and 802.11ah offer faster data rates for multimedia IoT applications, while protocols like 802.11b/g have advantages in reducing power consumption. Therefore, the most suitable wireless IoT module for your project depends on your specific project requirements and use cases.


  • Operating frequency:

 The IEEE 802.11 standards operate within designated frequency ranges and are divided into multiple channels. Each country has its own rules and regulations to determine the usage, channels, and maximum power levels for these frequency bands. ThinkWill’s upcoming IoT modules will support both 5GHz and 2.4GHz frequencies, providing greater flexibility in operating frequencies for IoT devices and enhancing interoperability and compatibility.


Many wireless IoT modules produced by different vendors have identical specifications in terms of power consumption, size, and functionality. To find the best IoT module, you need to delve deeper beyond the comparison data table of module specifications.
