In Hall 1, which is quite large at the 2026 Mobile World Congress (MWC 2026), Huawei has occupied more than half of the space. With such a large area, the key word that Huawei wants to highlight is U6GHz.

To achieve the distant blueprint of 6G, recently, the world has witnessed a wave of exploration of U6GHz (6.425 - 7.125 GHz). Major operators in many countries such as the UAE, Brazil, and European countries have recently completed the verification of the corresponding 10 - Gigabit experience rate.

Put simply, U6GHz is like a "golden frequency band". Since it has achieved the best balance in the three dimensions of capacity, coverage, and cost, it is about to become the core resource for the expansion and upgrading of mobile networks in the next decade. It can be regarded as the key "high - speed road" for the future deployment of 5G - A and 6G.

During MWC 2026, Huawei released a series of products and solutions related to U6GHz, covering the complete matrix of macro - stations, small - stations, and microwave systems.

Although U6GHz has many advantages, it is not perfect. It has the inherent shortcomings of high frequency and large loss, just like being unable to "travel long distances".

To address this, Huawei has launched the "AAU product series matrix". The biggest breakthrough is that, compared with traditional antennas that may have only dozens of transmitting and receiving units, the AUU integrates 256 units, just like miniature flashlights.

In addition, Huawei has also incorporated a digital - analog hybrid intelligent beamforming algorithm into the AUU. Its function is to control these 256 miniature flashlights to work together and form a super - strong signal spotlight.

This combination of dense antenna units and algorithms means that the limited signals can be concentrated to compensate for the loss of high - frequency signals during propagation. According to Huawei, this set of combined measures will enable U6GHz to have a propagation distance and coverage effect similar to the current mainstream C - band (about 3.5 GHz) of 5G.

After solving the signal loss problem of U6GHz, Huawei has further considered how to make it achieve more extreme network performance. In this regard, Huawei's two major weapons are the 400 - MHz ultra - wide bandwidth and the super - resolution MU - MIMO algorithm.

It can be understood that Huawei has quadrupled the main channel from the original 100 MHz of 5G. A wider spectrum means that more data can be transmitted simultaneously, and the super - resolution MU - MIMO algorithm is like an intelligent traffic control system, which improves the efficiency of spectrum utilization.

According to Huawei's demonstration, with the support of these two capabilities, Huawei's U6GHz AAU can be greatly improved in two dimensions: peak capacity (downlink 100 Gbps / uplink 10 Gbps) and user experience rate (downlink 10 Gbps / uplink 1 Gbps).

Interestingly, a large number of future AI applications will occur indoors. Considering the problem of signal loss when U6GHz signals pass through walls, Huawei has also released U6GHz small - station products this time, enabling future indoor AI applications to use the "golden frequency band".

In this product, Huawei not only maintains the 400 - MHz ultra - wide bandwidth of U6GHz but also conducts a full - band integration. It integrates U6GHz with the existing frequency bands in one device - which is equivalent to providing different options in the same signal hotspot, allowing both new and old terminals to have a better experience.

If the aforementioned two products (AAU and small - station) respectively break through the "access" link of outdoor and indoor data, Huawei also pays attention to the data back - haul problem. Therefore, Huawei has also released microwave products to meet the high - bandwidth transmission requirements of U6GHz base stations, solving the problem of efficient back - haul of massive data.

It is reported that Huawei has introduced full - duplex technology, which can simultaneously send and receive data in both directions on the same frequency - which is equivalent to providing an ultra - high - bandwidth wireless back - haul solution that does not rely on fiber optics, ensuring that the capabilities of U6GHz base stations will not be restricted in the "last mile".

That is to say, Huawei has actually built a network closed - loop around U6GHz. Only when these three work together can the smooth data path from AI terminals, to base stations, and then to the cloud be ensured. Currently, Huawei's full - series U6GHz products are commercially viable.
