Recently, GosuncnWelink GM120 module has completed CCC approval and network certification, and GM120 has officially entered China Telecom product list. So far, this new NB-IoT module has successfully obtained Chinese regulatory certification and operator certification requirements and entered the stage of large-scale promotion. Excellent performance and highly competitive product configuration, it is a perfect solution for the smart water meter and smart gas meter industry which can provide customers with reliable low-power connection technology.

GM120 module uses the core wing information technology highly integrated single-chip solution XY1100, supports the 3GPP R14 protocol version, it uses an ultra-small package of LCC 16mm×18mm, and is compatible with the ME3616 design. GM120 supports NB-IoT B3, B5, B8 frequency bands, which can support the three major operator networks in China, seamless switching. In terms of low power consumption performance, the operating current in PSM mode is reduced to 0.7μA, the current in eDRX mode (2.56s) is reduced to 120μA, and the power consumption performance in sleep mode is increased by up to 80%.

Reliable connection performance and strong low power consumption advantages make it especially suitable for industrial applications such as smart water meters and smart gas meters. At present, GM120 has won the favor of leading customers in the industry and entered the design of a new generation of smart gas meters. Developed around the GM120 module, customers can also reduce the number of peripheral devices by 60%, further gaining a double boost in overall power consumption and cost performance.

The GosuncnWelink NB-IoT lineup continues to expand. GM120, ME3616, and GM100 modules will form a GosuncnWelink NB-IoT multi-platform product portfolio. NB-IoT modules line takes advantage of product capabilities in different fields to win the trust of customers in the global market.

200 million NB-IoT connection is just around the corner. During the explosive growth period in 2020, the GosuncnWelink GM120 module is coming, working hand in hand with industry customers to jointly promote the prosperity and development of the NB-IoT industry.
