Huawei recently released a 5G antenna technology called CableFree. This technology comes with major breakthroughs in key areas such as base station antenna integration, radiation efficiency, and power capacity. This device starts a new phase in the development of antennas in the 5G era. According to the company, CableFree technology breaks through the current antenna design bottleneck. It also effectively improves the antenna’s capabilities in all aspects.
Huawei’s new CableFree antenna, like its name, comes with a cable-free design. It also integrates a phase shifter design which improves antenna integration and antenna performance. CableFree technology has already been used for a couple of Huawei devices including Huawei’s Munich Pro, Golden Mini, and London Pro series antennas, as well as 32T32R Massive MIMO products. This helps customers to quickly deploy high-quality 5G networks.
Some technological advancement of Huawei’s CableFree
- Good high-band coverage: 5G uses a higher frequency band and requires higher antenna for better coverage. At the same time, 5G network coverage needs to be coordinated by multiple frequency bands. If 1.8GHz / 2.1GHz and other frequency bands are used as 5G uplinks, high-frequency coverage plays an important role in the continuity of 5G experience. CableFree technology improves antenna radiation efficiency by approximately 20%. This also increases the antenna coverage quality.
- Meets higher power and frequency demand: In the 5G era, large-capacity and high-speed requirements need the use of more spectrum and higher-order MIMO. The antenna load power increases from five or six hundred watts to more than one kilowatt. CableFree technology improves the antenna power capacity by more than 80%. With this, it meets the greater output power requirements of the 5G era.
- Lower weight, easy to install: The high degree of integration of antenna components effectively reduces antenna weight. Take the 6-band antenna as an example, the overall weight reduces by about 10kg. The weight of the control multi-band antenna is within 50kg. With this, it avoids the use of cranes, thus simplifying the installation process and saving installation costs.
- Antenna PIM performance is better: CableFree technology reduces 80% of the internal antenna screws and welding joints. With this, it also reduces the PIM risks. PIM means “Passive Intermodulation”. CableFree comes with fewer screws and joints thus it guarantees long-term PIM stability. This new architecture and process improve the production automation ratio. It also ensures better consistency of mass production performance.
