Antenna selection guide: industrial IoT
How to choose the right antennas for industrial IoT applications
Read guide
Industrial antenna choice must balance reliability, performance and coverage
The industrial IoT (IIoT) market is rapidly expanding as automation and digital transformation reshape industrial operations. Forecasts predict that IIoT will grow by almost US$200 billion between 2024 and 2029, with industrial automation driving around 40% of expenditure. Antenna selection plays a central role in IIoT device design, directly influencing whether equipment connects reliably or suffers interruptions and failures. As a result, manufacturing of IIoT antennas is also growing, with antennas diversifying to span many technologies and form factors.
Ultimately, success in IIoT depends on creating scalable, rapidly deployable solutions that remain simple to set up, maintain and operate. Antennas pose a range of crucial challenges in device design, with antenna selection beginning with choices between indoor, outdoor, high-performance or ruggedized antennas. Good industrial IoT antenna selection however ultimately aligns many factors related to the device, environment and connectivity technology in use.
In many industrial scenarios, interruptions, failures, setup delays and complex configuration are unacceptable and – with volumes of IIoT devices hitting mass scale – optimized antenna selection has become essential.
Antenna selection means weighing up a range of often competing factors. In reality, it is frequently difficult to find the option that combines the optimal size, performance and cost. Decision-making often requires considerable expertise in the specific engineering context. For example, issues such as interference, signal reception and propagation need to be carefully considered when antennas are installed in assets such as heavy equipment or robots. Industrial environments also frequently involve other challenges such as temperature extremes, vibration and electromagnetic noise.
Relevant products
Quectel provides a broad portfolio of antennas optimized for IIoT. The range includes 5G, Wi-Fi, LTE, ISM, and GNSS antennas, with hundreds available off-the-shelf. We also offer a rapidly growing range of combination antennas that integrate multiple technologies. We also bring deep expertise to antenna design for IIoT devices, with our global R&D team ensuring antennas operate reliably across all networks while managing interference and mechanical constraints.
Many IIoT products require custom antenna development rather than off-the-shelf antennas. This is particularly likely where engineers embed antennas into equipment or deploy them in challenging industrial conditions. Our Antenna Services therefore include custom design services as well as technical requirement analysis, simulation and integration guidance.
