Fujitsu Open RAN Solution
Radio Access Network Solution for Mobile Networks
Mobile operators must respond flexibly and dynamically to growing market demands by installing numerous high-capacity, high-speed base stations over wide areas. To help them achieve this goal, Fujitsu supports 5G evolution with open, customizable equipment and an integrated network architecture. Open interfaces are essential to enable mobile operators to introduce their services expediently, or customize their network to their unique needs.
Operators face critical challenges as they install 5G architecture, including how to use available spectrum efficiently and reduce deployment and operational costs. The Fujitsu Open Radio Access Network (RAN) solution provides the flexible network configuration and extension required for the 5G network, reducing cost in several ways:
- Fujitsu's Open RAN solution combines flexible and scalable products with open standards, across multiple technologies.
- Fujitsu ensures that this entire ecosystem is tested and pre-integrated as a complete solution. Fujitsu may also offer each product separately.
This approach ensures that all components work together and meet Fujitsu's quality standards, as well as helping to control costs.
