[Hohhot, China, October 18, 2021] China Unicom Hohhot and Huawei completed the initial test of the latest XMC-3E ODU product. The test used a 112-MHz channel space and the high-order 4096QAM modulation scheme, and achieved a single-channel bandwidth of 1.37 Gbps on a single ODU module. That is more than double the throughput of a conventional ODU module.
Huawei microwave aims to provide ultra-broadband and simplified solutions. The XMC-3E is the latest of the ODU products it has launched towards this endeavor. In June, 2021, this product won both the Red Dot Design Award and the iF Design Award, two prestigious awards that honor the highest quality of industry design. Featuring a sleek appearance, the ODU is easy to install and maintain and supports 112 MHz ultra-broadband and up to 8192QAM high-order modulation. This level of capability provides operators with a strong basis to pursue simplified deployment and boost spectral efficiency. In addition, its unique ergonomic handles and quick-lock mounts ensure safer and more efficient installation.
This test was conducted in Naobao Village, in the northeast of Hohhot in China’s northern Inner Mongolia region. Located 18 km away from downtown, this village is a time-honored tourist destination, which is now more than 300 years old. This solution was regarded as essential for the mobile backhaul of network services in this village.
The test confirmed that a single XMC-3E ODU product can stably provide a throughput of up to 1.37 Gbps without any bandwidth accelerator features thanks to its support for a channel bandwidth of 112 MHz and 4096QAM high-order modulation. This is a record high throughput for a single ODU module over a single channel.
With a transmit power 1.5 dBm higher than that of current high-power ODU modules, the XMC-3E boasts a transmission distance of dozens of kilometers when working on low bands (6 GHz, 7 GHz, and 8 GHz). Such performance is an effective alternative to decreasing antenna diameters and relaxing the requirements on tower space and load bearing. It lends itself to both high bandwidth and wide coverage, which are particularly needed for mobile networks in sparsely populated areas.
Jia Yuetian at China Unicom Hohhot’s Network Division said: “Huawei’s XMC-3E series enables us to improve both network bandwidth and quality for suburban users, and its simplified construction makes medium- and long-reach deployments more efficient, putting us in a good position to improve user experience.”
