OREX Open RAN Service
Docomo said in an announcement that the introduction of the OREX Open RAN service is expected to reduce the total cost of ownership (TCO) by up to 30 percent, when initial setup and ongoing maintenance costs are taken into account.
The service can also be customized to address the unique challenges of each customer. It is also said to reduce the time required for network design by up to 50 percent and power consumption at base stations by up to 50 percent.
In the OREX RAN offering, OREX leverages the features of Open RAN, allowing the combination of various vendor products to provide base stations that are highly cost-effective.

Docomo said that OREX integrates the strengths of its 13 OREX Partners to offer an extensive range of virtualised radio base networks (vRANs) and radio units (RUs) compatible with the range of different frequencies in use in various countries.
With the addition of seven new RU vendors, DENGYO, DKK, Fujitsu, HFR, Mavenir, NEC Corporation, and SOLiD, Docomo said OREX is poised to meet the demands of an even larger customer base.
