For many implementations, LTE Cat 1 bis is becoming an alternative to the aforementioned LPWA technologies. 4G IoT connections grew by 24% due to higher adoption of LTE Cat 1-, Cat 4-, and Cat 6-based chipsets.

Users are moving away from legacy 2G/3G toward 4G/5G IoT.

NB-IoT adoption (finally) took off, with connections growing by 61% YoY, driven by a wide variety of implementations, most notably in the areas of water and gas metering.

LPWA networks expanded, especially those using NB-IoT technology.

These are some key trends that impacted the growth of the number of connected IoT devices in 2021: Here is what impacted IoT connections in 2021, where we stand in 2022, and where we may be headed beyond 2022: IoT in 2021: Selected IoT connection growth highlights (The previous estimate for 2021 was 12.3 billion connected IoT devices the previous forecast for 2025 was 27.1 billion connected IoT devices). It is expected that by 2025, as supply constraints ease and growth further accelerates, there will be approximately 27 billion connected IoT devices.īoth the 2021 actuals and the current 2025 forecast for IoT devices are lower than previously estimated. In 2022, the market for the Internet of Things is expected to grow 18% to 14.4 billion active connections. Other headwinds for IoT markets include the ongoing COVID-19 pandemic and general supply chain disruptions.

The number of global IoT connections grew by 8% in 2021 to 12.2 billion active endpoints, representing significantly lower growth than in previous years.ĭespite a booming demand for IoT solutions and positive sentiment in the IoT community as well as in most IoT end markets, IoT Analytics expects the chip shortage’s impact to the number of connected IoT devices to last well beyond 2023. The chip shortage continues to slow the Internet of Things (IoT) market recovery, according to our latest State of IoT-Spring 2022 report, released in May 2022.
