Huawei shows 5G Already in March, Huawei had at the MWC Shanghaicurrent solutions for “1+N” 5G target networks were present. The offers were now also on display at the Mobile World Congress 2021 in Barcelona and were place by the provider in a larger context for global economic progress and sustainability.
“Carbon Handprint” and “1+N”
David Li, President of Huawei Western Europe, explains: “We support other industries in reducing their carbon footprint through ICT solutions. We call this our ‘Carbon Handprint’. The industry’s carbon footprint only accounts for about two percent of total emissions. But with the help of ICT technologies, total global emissions can be reduce by up to 20 percent.”
With “1+N”, Huawei describes 5G infrastructures that are based on a universal, broadband infrastructure; in addition, “N” stands for a simplified deployment of fragmented bands (“overlay advantage”).
In detail, Huawei is promoting the industry’s only 400 MHz ultra-wideband 64T64R massive MIMO. This uses leading technologies and algorithms in the field of ultra-wideband radio as well as power amplifiers for the entire C-band. Operators can use their multi-segment spectrum on just one module to reduce the number of devices. In addition, the product offers a large bandwidth and high capacity, so that one module can be shared by multiple operators.
According to Huawei, the 64T64R Massive MIMO product is the lightest of its kind: a single module weighs 19 kilograms. The new 64T products can therefore be transport and install by one person and require less space than previous solutions.
Blade AAU integrates active and passive antennas
The Blade AAU (AAU = Active Antenna Unit) integrates South Korea Phone Number List active and passive antennas in one box, making it the first choice for sites with limited space. The latest Blade AAU Pro is 64T capable while offering a high level of A+P integration. The active module has been improved with 64 channels compared to the previous 32 channels, supports a transmit power of 320 watts and a bandwidth of 200 MHz. The passive module has also been improved: the port specifications have been increased to 2L6H to enable full sub-3GHz coverage. Huawei’s entire BladeAAU series received the “Best Mobile Network Infrastructure ” award from the GSMA.
Using sub-3GHz spectrum efficiently
According to Huawei, the efficient use of the fragment sub-3 GHz spectrum has become a common challenge for global operators. Traditional RF solutions require one module for each cell phone number listing band. Huawei’s Blade RRU Pro (Remote Radio Unit) is the first system to integrate three low bands and three mid bands. This reduces the number of FDD RRUs require for full-band coverage by two-thirds.
Huawei offers a SingleCell software solution for BladeRRU Pro to coordinate scheduling between low and mid-bands, thereby freeing up more resources to serve low-band user equipment (UEs) at cell edges. Commercial deployment of the solution at multiple sites has shown that SingleCell can almost double the average experience indicators for these UEs.
Specifications of FDD-Massive-MIMO are base on TDD
While Massive MIMO has already been successfully commercialize on TDD bands, according to Huawei, FDD Massive MIMO still faces challenges in device dimensions, weight and Bulk Database performance. As a solution, Huawei claims to have launch the industry’s first commercial FDD massive MIMO products that combine an innovative meta-material array design and an ultra-miniaturize passive intermodulation (PIM)-free filter technology. The FDD massive MIMO device is less than 500 mm wide but offers technical specifications comparable to those of TDD massive MIMO. The cell capacity is five to six times higher than that of 4T4R while providing similar deep coverage performance to that of sub-1 GHz bands.
