The global market for Cat.1 bis Chip was estimated to be worth USD 1,203 million in 2025 and is projected to reach USD 1,834 million, growing at a CAGR of 6.3% from 2026 to 2032.
A Cat.1 bis chip is a highly integrated semiconductor device designed to support the LTE Cat 1 bis communication standard, which is standardized by 3GPP as an evolutionary extension of the LTE Category 1 specification specifically optimized for low-power wide-area network applications and Internet of Things devices. The defining architectural innovation of Cat 1 bis technology is its single-antenna design, which fundamentally distinguishes it from standard LTE Cat 1 chips that require dual receive antennas. By eliminating the second RF receive chain and its associated components, Cat.1 bis chips dramatically reduce the bill-of-materials cost, minimize the printed circuit board footprint, and simplify the industrial design integration for IoT product developers. Despite this streamlined architecture, the chips still deliver robust 10 Mbps downlink and 5 Mbps uplink data rates—sufficient for firmware-over-the-air updates, occasional image transmission, and responsive two-way communication—while supporting essential power-saving features including Power Saving Mode and extended Discontinuous Reception that enable multi-year battery operation for field-deployed devices. These semiconductor platforms are available in two principal configurations: single-mode Cat.1 bis chips that exclusively support LTE Cat 1 bis operation, optimized for cost-sensitive applications where multi-mode capability is unnecessary, and multi-mode Cat.1 bis chips that integrate support for additional radio access technologies including 2G GSM or narrowband IoT, providing a migration-safe connectivity solution that ensures devices can operate even in regions where LTE coverage remains incomplete. The chips serve as the foundational silicon building blocks for both standard-type modules, where the chip functions as a modem companion to an external host microcontroller, and Open CPU type modules, where the chip’s integrated application processor executes customer application code directly, eliminating the need for a separate host processor and enabling ultra-compact, cost-optimized IoT endpoint designs.

Market Development Trends and the 2G/3G Sunset Migration
The market analysis reveals that the Cat.1 bis chip industry is being propelled by a structural demand force of historic proportions: the coordinated global decommissioning of 2G and 3G cellular networks that is rendering obsolete the connectivity foundation of an entire generation of IoT devices. In the United States, all major carriers have completed their legacy network shutdowns. In Europe, operators including Vodafone, Deutsche Telekom, and Orange are systematically retiring 3G infrastructure across multiple markets. In China, the Ministry of Industry and Information Technology has designated LTE Cat 1 as the official migration path for medium-rate IoT applications, with state-owned operators China Mobile, China Unicom, and China Telecom actively subsidizing chip and module procurement to accelerate the transition. This government-directed push has established China as the epicenter of Cat.1 bis chip development and production. The development trend toward multi-mode chip architectures represents a strategic response to the fragmented global landscape of network sunset timelines: while developed markets are aggressively retiring 2G and 3G, many emerging economies will maintain these networks for years, creating demand for chips that can seamlessly fall back to legacy technologies when LTE coverage is unavailable while future-proofing devices for eventual 2G/3G retirement.
Competitive Dynamics and the Chinese Semiconductor Ecosystem
The competitive landscape for Cat.1 bis chips is dominated by Chinese semiconductor companies that have capitalized on the enormous scale of their domestic IoT market and strong government support for technology self-sufficiency. Unisoc Technologies, Eigencomm Technologies, and ASR Microelectronics represent the leading domestic chip designers, collectively supplying the silicon foundation for the massive Chinese LTE Cat 1.bis module industry that dominates global production. These companies have achieved rapid product development cycles and aggressive price points that have established China as the global center of Cat.1 bis chip innovation and manufacturing. China Mobile Communications Group, through its subsidiary chip operations, has introduced Cat.1 bis silicon as part of its strategic initiative to accelerate IoT connectivity adoption across its network. Sequans Communications represents a notable non-Chinese competitor with established positions in European and North American markets. Mlink Tech and Xinyi Information Technology serve specialized segments with differentiated chip architectures. The industry outlook suggests that Cat.1 bis chip demand will maintain strong growth momentum as the 2G/3G migration continues, with competition increasingly centered on integration levels, power efficiency, and the breadth of global carrier certification support that enables module manufacturers to address international markets with a single chip platform.
Application Ecosystem and the Standard vs. Open CPU Architecture Choice
The downstream application landscape for Cat.1 bis chips spans an extraordinarily diverse array of IoT verticals, each imposing distinct requirements that influence chip architecture selection. Asset tracking and telematics applications demand robust mobility management and reliable connectivity across cell boundaries, favoring chips with proven handover performance. Smart home and consumer IoT devices prioritize ultra-low standby power consumption to maximize battery life in compact form factors. Photovoltaic and renewable energy monitoring systems require extended temperature range operation for outdoor deployment. Vehicle networking applications demand automotive-grade reliability and long-term component availability commitments. The strategic choice between standard-type and Open CPU module architectures represents one of the most significant design decisions in the Cat.1 bis ecosystem. Standard-type modules implement the modem protocol stack on the chip while delegating application processing to an external microcontroller, offering maximum design flexibility and the ability to run complex application software on a processor optimized for that purpose. Open CPU type modules integrate an application processor within the Cat.1 bis chip itself, enabling developers to run custom code directly on the connectivity silicon without a separate host processor, dramatically reducing system cost, complexity, and physical footprint for simple IoT endpoints such as basic asset trackers, environmental sensors, and utility meters. The growth trajectory for Cat.1 bis chips is further reinforced by the expanding scope of IoT applications that require cellular connectivity: smart city infrastructure, agricultural monitoring systems, healthcare telemetry devices, and industrial predictive maintenance sensors all represent incremental demand vectors that will sustain chip consumption growth well beyond the initial 2G/3G migration wave.
