As CBN continues to accelerate the development of the global 5G 700MHz industry chain with its partners, the upstream and downstream of the industry chain have been actively engaged in 700MHz 5G embrace, continue to introduce chips, modules, terminals, and network equipment, and fully tap the advantages of 700MHz spectrum resources. Promote the acceleration of the 5G industry and lead the tide of "new infrastructure".

Recently, GosuncnWelink 5G module GM800 has completed the Model Approval Certificate (SRRC) supporting the 700MHz frequency band, becoming the first batch of 700MHz 5G modules in China to enter the commercial stage, adding another force to the prosperity of CBN 5G ecosystem.

700MHz has the characteristics of wide signal coverage and strong penetration, which is suitable for large-scale continuous network coverage. In 5G construction, the use of 700MHz networking can greatly reduce network construction and operating costs and has unique high-quality coverage advantages in both personal user services and vertical industry services. In March 2020, the 5G 700MHz band 2×30MHz large-bandwidth technical proposal formulated by CBN was adopted by 3GPP and officially became the 5G international standard, which is also the world's first 5G low-band large-bandwidth international standard. This greatly improves the efficiency of the use of 700MHz spectrum resources and provides new opportunities and possibilities for business innovation based on the 700MHz spectrum. In August 2020, CBN completed 700MHz data calls with Qualcomm and completed the world's first 5G 700MHz band 2*30MHz large bandwidth end-to-end system business demonstration and verification with Huawei, laying a solid foundation for China's radio and television 5G commercial use. GM800 is a 5G module developed by GosuncnWelink based on Qualcomm's SDX55 chip. It supports SA and NSA network deployment and supports 5G NR/4G/3G commercial network frequency bands in major regions and operators around the world. At present, GM800 has taken the lead in obtaining a network access certificate, model approval certificate, CCC certification, and operator certification. Joining CBN 5G 700MHz ecosystem, GM800 module will provide downstream customers with stable and reliable high-quality 5G connections based on the good coverage of the 700MHz spectrum. In the next step, GosuncnWelink will work with radio and television to continue in-depth cooperation in the 5G field, promote the integrated development of 5G communication and 5G broadcasting, support 5G streaming media broadcasting services and Internet of Things services for all scenarios, and bring personal users, home users, government and enterprise users come to a high-quality 5G connection experience.

Up to now, GM800 module has been widely used in multiple types of equipment including 5G inspection and epidemic prevention robots, 5G communication core control terminals, 5G industrial gateways, and dozens of customers have recognized GosuncnWelink's technical strength in the 5G direction.

As a new type of infrastructure and an important strategic resource supporting economic and social development, 5G is a key driving force to promote a new round of technological revolution and industrial transformation. GosuncnWelink 5G modules continue to innovate and join hands with CBN and many partners to contribute to the vigorous development of 5G!
