FREMONT, CA: Japan-based Fujitsu Laboratories announced the development of a new, high-speed computing technology to significantly streamline the deployment of wireless base stations compatible with 28 GHz millimeter-wave private 5G systems. Private 5G has shown great promise as a critical infrastructure technology to support digital transformation (DX) for various companies across different industries and business areas, delivering low-latency communications for applications as varied as AI video analysis on worksites to seamless remote operations for robots in manufacturing and medical facilities.

To realize the technology's true potential, it is necessary to optimize wireless base stations' deployment. This often proves challenging, and despite its wide bandwidth, the millimeter-wave band remains challenging to handle because of its susceptibility to interference, including obstruction by surrounding obstacles. Radio experts are often required to determine the correct location of wireless base stations to avoid this. This remains an expensive process and requires extensive field adjustments.

With its new technology, Fujitsu has successfully developed a high-speed algorithm that can automatically calculate the best placement for private 5G millimeter-wave base stations 5 to 10 times faster than conventional approaches. This technology also accounts for the adjustment of parameters, including transmission power, radio channel, antenna direction, and position, making it easier for non-radio experts to determine layouts for wireless base stations for private 5G systems. Fujitsu will continue to advance its automated design technology and aims to leverage it in the area design of its private 5G system integration service within fiscal 2020.

Previously, the company has developed an automatic wireless base station designed technology that enables non-specialists to design and install wireless LAN networks in a day or so, instead of the previous seven-day work required by wireless experts, by using radio wave simulation technology that makes use of the knowledge of network technology we have accumulated over the years. However, the millimeter-wave band is more direct than microwaves of 6 GHz or less, which to date have been used mainly in cellular and wireless LANs. Therefore, the millimeter-wave band is easily affected by surrounding obstacles, and the signal attenuation is significant when the distance between the base station and the terminal increases. As a result, it is essential to increase signal power and compensate for attenuation by directing radio waves to each terminal.
