5G RAN Solution
Radio Access Network Solution (RAN) for Mobile Networks
Mobile operators must respond flexibly and dynamically to growing market demands by installing numerous high-capacity/high-speed base stations over a wide area. To help them achieve this, Fujitsu is supporting the 5G evolution with open, customizable equipment and an integrated network architecture. Open interfaces are essential to enable mobile operators to introduce their services, or customize their network to adjust their unique needs. Mobile operators will face challenges in installing 5G architecture to use available spectrum efficiently and reduce deployment operational costs.
The Fujitsu RAN solution enables the flexible network configuration and extension required in the upcoming 5G network, reducing cost in several ways:
- Fujitsu's RAN solution is composed of flexible and scalable solutions across multiple technologies with Open standards.
- Fujitsu ensures that this entire ecosystem is tested and pre-integrated as a complete solution. Fujitsu may also offer each product separately.
This approach provides assurance that all components work together and meet Fujitsu's quality standards, which also helps customers to control costs.
Fujitsu Radio Proliferation
Fujitsu has a successful track record as a global RAN solution vendor:
- Fujitsu first supplied RAN infrastructure in 1995 (PDC system)
- Fujitsu's RU (Remote Radio Unit) was the world's first to be shipped, in 2004 (W-CDMA)
- Fujitsu has supplied wideband RU to the North America market since 2013
- Fujitsu has designed and supplied customer-specific frequency band combinations for dual- and triple-band applications since 2014
- Fujitsu has supplied 5G-RU and CU/DU since 2019
