Recently, the Ministry of Industry and Information Technology issued radio frequency use licenses to China Telecom, China Unicom and China Broadcasting, agreeing these three companies can jointly use the 3300-3400MHz frequency band for 5G indoor distribution coverage in China. This is the first time in China, which will help further realize the co-construction and sharing of 5G construction operators, save frequency resources, reduce cost and increase efficiency, and promote the development of 5G indoor distribution technology in China.

ZTT is a pioneer in the research and development of 5G indoor distribution co-construction and sharing technology in China. At the beginning of the construction of 5G indoor distribution in China, it carried out the research and development of new products and new solutions for 5G indoor distribution, and accelerated the globalization of 5G industrialization. At present, we have successively developed 5G indoor distribution products such as wide-angle indoor distribution, ROOFTOP indoor distribution and 5G fiber optical composite cable. 

ZTT's wide-angle indoor distribution and ROOFTOP indoor distribution technology can achieve 700MHz-3800MHz ultra-wideband compatibility, carrying 2345G of operators and the 3300-3400MHz frequency band issued this time. This product has passed the "new product and new technology appraisal” of Jiangsu Provincial Ministry of Industry and Information Technology, and its comprehensive technical performance has reached the international advanced level.
