NEC Corp announced today (30 July) the provision of radio units (RU) for 5G base station equipment to Japan’s leading mobile operator by subscribers, NTT DOCOMO. In a press release, the equipment maker said it has already begun shipping three types of small-cell RU that support the 3.7GHz, 4.5GHz and 28GHz bands, all of which are compliant with O-RAN fronthaul interface specifications – defined as ‘open interfaces between the master and slave stations of the base station defined by the O-RAN Alliance (Open Radio Access Network Alliance)’. NEC went on to note that the RUs are compact, lightweight and offer a low-power consumption solution via efficient heat transfer technology, which it claims makes it easier to install the RU on rooftops and walls of buildings, thereby reducing installation and operation costs.
In collaboration with DOCOMO, NEC says it has been developing products that are compliant with O-RAN fronthaul interfaces, an open interface, for 5G. NEC products will contribute for flexible 5G network deployments and support diverse use cases.
