Main features of the equipment are compact, lightweight, and low-power-consumption. It is installed with the base station antenna and connected with the base station controller through optical fiber using the O-RAN fronthaul interface specifications. This allows DKK&#8217;s radio unit to be connected with the base station controllers from different vendors that comply with the O-RAN fronthaul specification, and enables flexible network configuration not restricted to a specific vendor.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"602\" height=\"335\" src=\"https:\/\/denkikogyo.co.jp\/en\/wp-content\/uploads\/2022\/10\/5G\u5546\u7528\u30b5\u30fc\u30d3\u30b9\u5411\u3051\u7121\u7dda\u88c5\u7f6e-\u30b3\u30d4\u30fc.jpg\" alt=\"\" class=\"wp-image-6438\" \/><figcaption class=\"wp-element-caption\">DKK\u2019s wireless equipment for 5G commercial services<\/figcaption><\/figure><\/div>\n\n\n<ul>\n<li><strong>Outlook for the future<\/strong><\/li>\n<\/ul>\n\n\n\n<p>DKK has mainly supplied base station antennas to NTT DOCOMO, so this is DKK&#8217;s first shipment of radio unit to NTT DOCOMO.<\/p>\n\n\n\n<p>We recognize that this delivery is the first step in the radio unit market towards full-scale entry into the wireless equipment market with outcomes of research and development at the DKK Wireless R&amp;D Center established in 2019.
