On September 25-27, 2024, the China International Information and Communication Exhibition (PTEXPO2024) was grandly held at the Beijing National Convention Center, where technology elites and industry partners from all over the country gathered to share insights and experiences. SageRAN participated in the event, with the theme of "Unlimited Connectivity For a New Era", comprehensively showcased the innovative applications of the global interconnection platform solution for satellite base stations and the 5G/5G-A full scene coverage solution, attracting a large number of guests and audiences to stop and discuss on site. The atmosphere at the booth continued to heat up, laying a solid foundation for future cooperation.

NTN Satellite-based BS Global Interconnection Platform

With the rapid development of China's satellite communication industry, the integration of space and ground communication has become a trend. SageRAN is a leading provider of core software for full stack communication of satellite Internet. Its newly launched "NTN Satellite-based BS Global Interconnection Platform" shows its outstanding strength in the field of satellite communication. The platform has completed the independent research and development of core technologies such as load system software, satellite terminal software, twin modeling platform, semi physical simulation verification platform, and realized the autonomous control of the core software of the whole stack communication of satellite Internet.  In blind spots of cellular network coverage such as vast oceans, remote suburbs, and earthquake disasters, there is no need to rely on ground base stations anymore. By using terminals and satellites, signals can be "always online".

XLink™ 4+5G Distributed Base Station consists of BBU and indoor/outdoor RRU,  supports 6x4G cells and 6 5G cells simultaneously, achieving 400 users per 4G cell and 1200 users per 5G cell. It has the characteristics of high performance, flexible networking, and high scalability. It can achieve supplementary coverage of indoor and outdoor distributed hotspots in densely populated areas such as stations, shopping malls, and office buildings, as well as private network coverage in industrial parks, mines, and other places.

XLink™ mmWave Distributed Base Stations have advantages such as large bandwidth, low latency, and high positioning accuracy. It has flexible frame structure configurations, support multiple networking methods and beam management mechanisms, and have air interface latency as low as 2ms. They can be widely deployed in industrial scenarios with strict requirements for speed and latency.

Unity™ Outdoor Integrated Base Station combines self-developed BBU and RRU of SageRAN to achieve integrated 5G base station functions, which can quickly provide carrier grade reliable 5G wireless coverage network for users. The product has the advantages of compact structure, small size, and convenient engineering construction, supports customized frequency bands, power, and capacity. It is particularly suitable for applications in 5G+vertical industries such as smart mines and smart parks, as well as for application scenarios that require large-scale 5G coverage in suburban and rural areas.

Unity™ 4+5G Indoor Small Cell is a compact, energy-efficient, dual-frequency small cell that integrates BBU and RRU, with built-in antennas. It is easy to install and occupies minimal space. This device offers a cost-effective indoor coverage solution, catering to areas overlooked by macro cells. It supports a range of flexible backhaul methods, efficiently eliminating signal blind spots.

5G positioning solution based on Intel®architecture

SageRAN, together with Intel and East China Normal University, has jointly launched a 5G positioning solution based on Intel®architecture, relies on the SageRAN’s extended small base station, which includes a baseband unit (BBU), an extension unit (EU), and a radio frequency unit (RRU). The extended small base station adopts Intel technology ®Xeon® processor and Intel ®FlexRAN architecture server, combined with the 5G based multi-dimensional information fusion fingerprint positioning algorithm developed by East China Normal University and the estimation distance ratio positioning algorithm based on Difference of Reference Signal Strength (DRSS) measurement values, significantly improves the performance of positioning algorithm processing and achieves accurate and fast target positioning.

Based on the present and looking to the future, SageRAN will continue to uphold the corporate vision of "providing universal and high-quality wireless network technology to the world", actively embrace the opportunities and challenges brought by the development of mobile communication, continue to strengthen core technology innovation, focus on key areas and major needs of network coverage, and create a series of products and solutions that meet user needs, work together with industry partners, and inject "new momentum" into the communication technology revolution and industry.
