Intracom Telecom has successfully completed an extended field test of its high capacity E-Band radio system, UltraLink™-GX80, in China Mobile's network, China's largest mobile operator. The field test took place during the 2020 China Mobile Emergency Skills Competition Finals, that was held in Changsha, Hunan province, China.
The field test was driven by China Mobile's strategic requirement to achieve significant savings on site related works and the last mile Radio Access Network (RAN), replacing the fibre cable connection between the analogue and the digital part of a 4G / 5G base station wirelessly, while ensuring the same standards of services.
More specifically, the field test implemented a fronthaul application in CPRI option 7 where the digital part of the 4G base station BBU (Baseband Broadband Unit) was connected and synchronised with the RRU (Remote Radio Unit) via the UltraLink™-GX80 platform. The setup delivered 10 Gbps capacity with the maximum modulation scheme of 512-QAM at 1500 MHz. Two CPRI configurations have been tested: Star (one BBU – one RRU) and Cascade (one BBU – two RRUs).
In this event Intracom Telecom demonstrated the interoperability, the capacity and the stability of the UltraLink™–GX80 platform to serve multiple 4G / 5G cellular networks. As, in both configurations, all the performed tests were completed successfully, proving that UltraLink™-GX80 fully supports all the required functionalities for C-RAN applications.
