It added that this new gear significantly lowers installation footprint, reduces construction and equipment costs and lower power consumption.<\/p>\n<p>\u201cThis marks a major step forward for 5G infrastructure in Japan,\u201d said JTower, adding that the shared radio units are compliant with the Sub6 bands used by all four national operators.<\/p>\n<p>The need for high-capacity networks continues to grow as mobile traffic surges due to widespread use of video, social media, web conferencing and now generative AI, the firm said, adding that it aims to support this demand by enabling more efficient and sustainable network deployment.<\/p>\n<p>The company also highlighted that it designs and builds shared systems internally to meet the stringent quality and operational standards of Japan\u2019s mobile operators. This includes joint reviews, testing and certification processes to ensure seamless network integration.<\/p>\n<p>Looking ahead, JTower said it plans to continue its investment in shared infrastructure innovation \u2014 including potential fronthaul sharing \u2014 to support Japan\u2019s growing digital ecosystem and the nationwide rollout of 5G networks.<\/p>\n<p>In August 2024, U.S. investment firm DigitalBridge Group <a href=\"https:\/\/www.rcrwireless.com\/20240815\/featured\/digitalbridge-launches-offer-to-acquire-jtower-in-take-private-deal\" target=\"_blank\" rel=\"noreferrer noopener\">offered<\/a> a 152% premium for JTower in a deal that valued the Asian telecom infrastructure company at around ($630 million.<\/p>\n<p>In Japan\u2019s telecom industry, carriers are facing growing pressure to expand coverage not only for rural and disaster-prone areas, but also for the sky, sea and even outer space, all while grappling with a shrinking population and limited human resources. JTower said maintaining and operating communication infrastructure reliably under these conditions has become a major challenge.<\/p>\n<p>\u201cIn this context, there is a growing need to improve the efficiency of indoor and outdoor network development and the maintenance and operation of communication infrastructure through infrastructure sharing,\u201d said the company.<\/p>\n<p>JTower also said that its capital investment and system reinforcement in the indoor infrastructure sharing business and tower business, as well as initiatives to upgrade the sharing area, will require responding flexibly to future additional funding needs and making up-front investments from a long-term perspective.<\/p>\n<p>However, the company noted that there is a possibility of restrictions on raising funds in the stock market due to share-price conditions, and the market has a strong tendency to prioritize short-term profitability, which makes it difficult to make up-front investments for future growth. <\/p>\n<p>The company, though, said it has received commitments from DigitalBridge to provide additional equity after JTower goes private via the ongoing tender offer. This move is expected to enable more agile and stable growth funding and allow the company to invest with a long-term view.<\/p>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>JTower said it will begin interoperability testing with Japan\u2019s four mobile carriers in fiscal year 2025 In sum \u2013 what to know: Japan\u2019s first Open RAN 5G radio \u2013 JTower\u2019s new shared unit supports Sub6 bands across four operators, using O-RAN for flexible vendor interoperability.
