Huawei recently released a 5G antenna technology called CableFree, which has made major breakthroughs in key areas such as base station antenna integration, radiation efficiency, and power capacity, and marked a new era of antenna development in the 5G era.

According to IT Home, Huawei's CableFree technology has broken through the current bottleneck of antenna design, effectively improving the capabilities of the antenna in all aspects.

1) 5G has better high frequency coverage. 5G uses higher frequency bands and requires higher antenna gain to provide higher coverage. At the same time, 5G network coverage requires multi-band coordination. For example, using 1.8GHz/2.1GHz and other frequency bands as 5G uplink, high-frequency coverage plays an important role in the continuity of 5G experience. CableFree technology improves antenna radiation efficiency by about 20%, thereby improving coverage quality.

2) Meet the greater output power demand brought by more frequency bands and more channels in the 5G era. The large-capacity and high-speed requirements in the 5G era require the application of more spectrum and higher-order MIMO, and the antenna carrying power will increase from five or six hundred watts to more than one kilowatt. CableFree technology increases the antenna power capacity by more than 80%, meeting the greater output power demand in the 5G era.

3) Reduce the weight of the antenna, easy to install and deploy. The high integration of antenna components effectively reduces the weight of the antenna. Taking the 6-band antenna as an example, the overall weight is reduced by about 10kg, and the weight of the multi-band antenna is controlled within 50kg, avoiding the use of cranes, thereby simplifying the installation process and saving installation costs.

4) The antenna PIM performance is better. CableFree technology reduces 80% of the screws and welding points inside the antenna, reduces PIM risk and ensures long-term PIM stability; its new architecture and process improve the proportion of production automation and ensure better consistency in mass production performance.

IT House learned that CableFree technology adopts technologies such as cable-free feeding design and integrated integrated phase shifter design, which improves antenna integration and antenna performance. CableFree technology will be applied to Huawei Munich Pro, Golden Mini and London Pro series antennas, as well as 32T32R Massive MIMO and other products.
