A dramatic shift is underway in the world of cellular IoT, moving beyond simple growth to a fundamental reshaping of the industry. While unit shipments are surging, revenue growth is leveling off, signaling a powerful trend toward ultra-low-cost connectivity solutions.
This transformation is being fueled by massive demand from China and India, particularly for LTE Cat.1 bis technology. Global device manufacturers are now aligning their strategies and certifications to these dominant ecosystems, anticipating a future defined by affordability and widespread adoption.
However, a potential roadblock looms on the horizon: constraints in DRAM supply. This could significantly impact the development of sophisticated, high-end industrial applications, potentially pushing innovation towards simpler architectures or even non-cellular alternatives.
The United States is charting a unique course, with early adoption of 5G RedCap technology. This divergence foreshadows a more fragmented global landscape for cellular IoT, where regional preferences and network strategies will play a crucial role.
Despite these challenges, the overall outlook remains strong. Cellular IoT module shipments are projected to reach 544 million units by 2025, representing a remarkable 23% growth rate. This expansion isn’t limited to industrial applications; consumer-focused devices are also driving demand.
A key driver of this growth is emerging regulatory pressure. In China, new rules mandating GNSS tracking for e-scooters – a market shipping 60-65 million units annually – are creating substantial demand for LTE Cat.1 bis modules. Spain’s requirement for emergency lights in vehicles, needing approximately 30 million NB-IoT modules in 2025 alone, is another example.
Smart home applications are also gaining traction, particularly in China, where extremely low data costs and module prices are encouraging the use of LTE Cat.1 bis over traditional Wi-Fi for continuous data collection.
Globally, LTE Cat.1 bis is solidifying its position as the dominant connectivity standard, capturing 63% of total cellular IoT module shipments by 2025. This is largely due to the sunsetting of 2G and 3G networks, leaving Cat.1 bis as the practical choice for mass-market devices.
While cellular LPWA technologies like NB-IoT and Cat-M currently hold a significant share, their growth is expected to slow. NB-IoT is experiencing a temporary boost in Europe due to Spanish regulations, but is otherwise maturing in China. Cat-M faced oversupply issues but is poised for recovery.
5G remains a niche player for now, representing a tiny fraction of total shipments. However, the U.S. market is leading the charge towards 5G RedCap and eRedCap, driven by operator plans to transition to all-5G networks. The arrival of affordable Chinese chipsets will further accelerate this adoption starting in 2027-2028.
The impending shutdown of 4G networks by AT&T and T-Mobile in the U.S. is accelerating the migration to 5G. This makes the U.S. the first mover in adopting 5G RedCap and eRedCap modules, a trend not yet mirrored globally.
The competitive landscape is heavily influenced by Chinese vendors, who control approximately 90% of the module market and 85% of the chipset market. Companies like China Mobile IoT, SunSea, and Lierda are expanding their reach through aggressive pricing strategies.
Non-Chinese suppliers are rebounding as inventory issues ease, maintaining a foothold in segments requiring high security and government oversight. Several Chinese module makers have even established alternative corporate structures to ensure continued access to Western markets.
India is also emerging as a key player, with new local suppliers like Cavli Wireless gaining prominence, driven by geopolitical factors and a growing preference for domestic solutions. Cavli Wireless now holds roughly 10% of the Indian market.
In the chipset arena, ASR, Eigencomm, Xinyi, UNISOC, and Qualcomm dominate, but Chinese suppliers are leading the charge in low-end technologies like LTE Cat.1 bis and 5G RedCap. HiSilicon is expected to gain significant ground in the coming years, particularly in the 5G RedCap segment.
The looming DRAM shortage presents a critical challenge. Devices relying on legacy DDR3/DDR4 – including smart handhelds, cameras, and industrial PCs – could face supply constraints and price increases as early as 2027, potentially reshaping the entire industry.
