How Cat.1 bis Technology Solves the
  The Internet of Things (IoT) is entering its second phase — a shift from "multi-point connectivity" to "intelligent scenarios."  Traditional smart home devices are moving beyond indoor environments into outdoor spaces that lack stable power and network access. Asset tracking is expanding from localized monitoring to global roaming, while AI-powered wearables are pushing the limits of battery technology as computing demands rise.  To address these challenges, the global Cat.1 bis standard is emerging as a key enabler. With its streamlined integrated design, ultra-low microamp-level power consumption, and global single-SKU compatibility, Cat.1 bis provides a breakthrough solution for mobility and endurance in next-generation smart devices.  New Battlefield for IPCs: From "Fixed Sentries" to "Mobile Detectives"  IPCs (Internet Protocol Cameras) are evolving rapidly from traditional indoor home security systems toward mobile, portable, and multi-scenario applications. Users now demand outdoor devices that can operate in "off-grid, weak-network" environments and portable cameras capable of capturing "brilliant moments" anytime, anywhere.  However, once IPCs go outdoors, unstable networks and limited battery capacity become major constraints. How can video transmission remain stable during movement? How can a camera stay on standby 24/7 without missing key footage or draining the battery? These challenges set extremely high standards for module size, mobility, and power management.  To cope with fluctuating networks in mobile scenarios, the new-generation Cat.1 bis technology introduces bandwidth adaptation, which dynamically adjusts bitrate based on real-time signal quality. This significantly improves bandwidth utilization and ensures smooth video streaming even in weak network conditions.  Meanwhile, to tackle battery anxiety, smart detection and flexible recording technologies are being deployed. A Cat.1 module can stay connected while only triggering recording upon detecting anomalies or critical events. This "microamp standby, millisecond wake-up" mechanism captures every key moment while extending standby time exponentially.  Asset Tracking: Building a Truly Global Network  As global supply chains expand, goods increasingly travel across continents. Traditional tracking solutions require different hardware models for each country’s frequency bands — resulting in SKU fragmentation, higher R&D costs, and complex inventory management. Furthermore, to ensure covert installation and long operating time, devices must continuously shrink in size and reduce power consumption to near-physical limits.  The global Cat.1 bis module solves this through multi-region compatibility, enabling a single device to achieve "one hardware, worldwide connectivity." Enterprises can maintain a single SKU that meets network certification requirements across major global operators. This not only reduces management complexity and cost but also enables seamless roaming for cross-border asset tracking.  With its compact, integrated hardware design, the next-generation module minimizes PCB footprint to meet the "ultra-compact" demands of locators. Combined with software-level power optimization, standby consumption is reduced to the microamp level — allowing even coin cell–sized devices to deliver long-term asset protection.  AI Companions and Wearables: The Art of Balancing Performance and Efficiency  Driven by large AI models, new categories such as AI companion dolls and senior health trackers are booming. These devices embody the “have it all” dilemma — balancing the demanding requirements of AI voice interaction for speed and mobility access, cost efficiency for mass adoption, and large batteries within compact designs to support intensive AI operations. This transformation demands multi-functional connectivity.  Cat.1 bis perfectly meets the speed requirements for both voice interaction and data transmission, avoiding the overkill and high costs of advanced LTE modules. For AI-driven devices that frequently wake from standby, Cat.1 bis optimizes power consumption and sleep mechanisms at the software level, achieving an efficient balance between connectivity and computational efficiency. Its compact hardware design also makes wearables lighter and more comfortable, enabling truly all-day intelligent companionship.  Conclusion: The Core Enabler of the Next IoT Evolution  From mobile IPCs to globally connected trackers and long-lasting AI wearables, every leap in IoT devices pushes the limits of connectivity technology. The new-generation global Cat.1 bis is rising to the challenge with three core capabilities — high compatibility, cost efficiency, and intelligent adaptability (including bandwidth self-adjustment, smart sleep, and single-SKU global support).  Cat.1 bis not only achieves unprecedented compactness and power efficiency in hardware but also establishes a unified connectivity foundation for Chinese smart manufacturing to expand globally.

Industry’s Highest* Rated Power! ROHM Unveils the UCR10C Series of Sintered Metal Shunt Resistors
  ROHM has developed the “UCR10C Series”, which has the industry's highest rated power for 2012-size shunt resistors (10 mΩ to 100 mΩ).  Shunt resistors are required to handle higher power for current sensing in both the automotive and industrial equipment markets. Additionally, specific requirements for high junction reliability in these markets has increased annually.  ROHM’s new products form a copper-based resistive element on an alumina substrate via sintering. By optimizing the heat dissipation structure, it achieves rated powers of 1.0W and 1.25W-double that of equivalent-sized products including thick film types and metal plate types. This enables the replacement of products with wide terminal types or larger alternatives, facilitating miniaturization and reducing the number of components required.  Furthermore, the use of a metal resistive element achieves a low TCR (0 to +60 ppm/°C). This minimizes errors due to temperature changes, enabling high-precision current sensing. Moreover, it achieves the same level of durability as the metal plate types in temperature cycle testing (-55°C / +155°C, 1000 cycles). This ensures high bonding reliability even in applications with extreme temperature fluctuations, such as automotive use, enabling stable, long-term operation.  This series is fully lead-free. No lead materials are present, even in RoHS-exempted areas, thus reducing environmental impact.  As part of its future expansion plans, ROHM has also commenced development of the 3216-size (2W) sintered metal shunt resistor, the “UCR18C Series”, further enhancing its product line-up that combines high power, high precision and high reliability.  Application Examples  Various current detection applications in automotive, industrial equipment, and consumer electronics.
