在物联网设备呈爆发式增长的今天，稳定、高效、低功耗的通信连接成为众多行业数字化转型的关键。古桥信息科技(郑州)有限公司（下称“古桥信息”）联合海思，于2025年11月正式推出基于海思Hi2131平台的全新Cat.1模组——GC33H-B，以全国产化、高性能、强兼容等优势，为客户带来更优无线通信的解决方案。
Today, amid the explosive growth of IoT devices, stable, efficient, and low-power communication connectivity has become a key enabler for the digital transformation of numerous industries. In collaboration with Hisilicon, Guqiao Information Technology (Zhengzhou) Co., Ltd. (hereinafter referred to as "Guqiao Information") officially launched its new Cat.1 module — GC33H-B — based on the Hisilicon Hi2131 platform in November 2025. Boasting advantages such as full localization, high performance, and strong compatibility, this module delivers superior wireless communication solutions to customers.
GC33H-B基于海思Hi2131平台开发，采用RISC-V架构，支持FDD/TDD LTE Cat.1 bis R14标准，实现从芯片到模组的全面国产化，保障供应链安全与稳定。
CapabilitiesThe GC33H-B is developed based on the Hisilicon Hi2131 platform and adopts the RISC-V architecture, supporting the FDD/TDD LTE Cat.1 bis R14 standard. It achieves full localization from chip to module, ensuring the security and stability of the supply chain.
模组尺寸仅为17.6mm × 15.7mm × 1.8mm，封装紧凑，可与行业上多型号全系列兼容，满足不同客户的需求，方便客户快速替换与升级，缩短产品开发周期。
With a compact module size of only 17.6mm × 15.7mm × 1.8mm and a streamlined package, it is compatible with multiple models and full product series in the industry. This meets the diverse needs of customers, facilitates their rapid replacement and upgrade, and shortens the product development cycle.
GC33H-B在功耗控制上表现卓越：
1. 休眠电流降低30%
2. 典型业务场景功耗下降20%
3. TDD网络DRX功耗（PF=128）压缩至150uA
4. 保活功耗降低超30%
真正实现“性能不妥协，功耗更节能”。
The GC33H-B excels in power consumption control:
1. Sleep current is reduced by 30%
2. Power consumption in typical service scenarios is decreased by 20%
3. DRX power consumption (PF=128) in TDD networks is compressed to 150uA
4. Keep-alive power consumption is reduced by over 30%
It truly achieves "no compromise on performance, yet greater energy efficiency".
下行信号接收比同类型模组平均提升1dBm，即便在地下停车场、电梯井等弱信号场景，仍能维持稳定通信，减少数据丢包和通信中断，确保设备的稳定运行。
The downlink signal reception is improved by an average of 1dBm compared with modules of the same type. Even in weak signal scenarios such as underground parking lots and elevator shafts, it can maintain stable communication, reduce data packet loss and communication interruptions, and ensure the stable operation of devices.
支持Audio PWM/I2S/ADC/USB/UART等多种接口供客户做OC开发，适配各类行业应用与定制需求。
