Global shipments of cellular IoT modules grow 39% y-o-y in 2021: Study

Quectel, Fibocom, Sunsea AIoT, Thales and Telit, hold 68% of the cellular IoT modules market in terms of revenues last year


European IoT analyst firm Berg Insight reported that annual shipments of cellular IoT modules reached 428 million units in 2021, an increase of 39% compared to the previous year.

Annual revenues from this sector grew even faster, at 54%, to reach US$ 5.3 billion, reflecting strong customer demand in a constrained supply environment, Berg Insight said in a release.

Even though supply chain shortage likely has caused some inventory build-ups, several vendors have reported continued strong growth in the first quarter of 2022, suggesting that short-term demand remains robust, the firm added.

The results of Berg Insight’s latest cellular IoT module vendor market share assessment show that the five largest cellular module vendors, including Quectel, Fibocom, Sunsea AIoT, Thales and Telit, hold 68% of the market in terms of revenues.

“Overall, the year 2021 was a record year for the cellular IoT module industry, in which all major vendors achieved double-digit growth. China-based vendors continue to outgrow the market, in part due to the significant growth in the domestic IoT market, which now accounts for more than 55% of global cellular module demand,” Berg Insight said.

The firm also noted that 4G LTE is the dominant technology as LTE Cat-1, NB-IoT and LTE-M replace 2G and 3G technologies in the low to mid-market segments. “LTE Cat-1 module shipments close to tripled in the year, driven by strong uptake in China, where chipsets from domestic suppliers supporting the single antenna version LTE Cat-1 bis are roughly half the price compared to standard LTE Cat-1 platforms,” the firm said. “Adoption of LTE Cat-1 in the country comes somewhat at the expense of NB-IoT shipments that recorded slowing growth year-on-year. Similar to the previous year, NB-IoT module shipments were largely confined to China. Internationally, NB-IoT module shipments are in the single-digit millions with demand primarily driven by smart gas meter and smart water meter deployments.”

Berg Insight also highlighted that LTE Cat-1 modules also account for a major share of the volume in North America, Europe and parts of the Asia-Pacific region, though LTE-M is viewed as an increasingly attractive alternative for IoT devices with stricter requirements on power consumption and long lifecycle. “As both LTE-M and NB-IoT are 5G-ready, they are suitable for IoT devices that will stay in the field for more than 10 years, which may prove critical as mobile operators in advanced markets will start to sunset their 4G LTE networks near the end of the decade. LTE-M module shipments today far exceeds NB-IoT shipments outside of China. The ability to perform over-the-air software upgrades of LTE-M devices has proven to be the key factor for the technology’s success compared to NB-IoT.”

The company also noted that 5G NR module shipments are starting to take off across product categories such as connected cars and IoT gateways. Berg Insight highlighted that 3GPP’s latest Release 17 introduced 5G NR support for reduced capability (RedCap) devices, expanding 5G NR to less complex IoT devices for higher-end applications that require faster speeds compared to LTE-M or NB-IoT. Enhanced RedCap (eRedCap) that is part of 3GPP Release 18 will offer improved energy efficiency and provide a migration path for LTE Cat-1 designs, according to Berg Insight.
