随着中国经济的发展和科学技术的进步,无线射频资源在当下社会经济领域各个方面起着举足轻重的作用,并带来极其深远的影响。800MHz/900MHz频段电波传输性能好、标签天线尺寸适中,适于远距离识别和大规模应用,是构建物联网和无线通信网的重要运行载体。该频段已分配给公众移动通信、集群通信、广播传输、航空导航等领域。该频段频率资源的规划、管理、共存、共容和有效利用关乎
With the development of China’s economy and advances in science and technology, radio frequency resources play an important role in all aspects of the current social and economic fields and have far-reaching implications. 800MHz / 900MHz band radio transmission performance is good, tag antenna size is moderate, suitable for long-range identification and large-scale applications, is building an Internet of Things and wireless communications network is an important carrier of the operation. The band has been allocated to public mobile communications, cluster communications, broadcast transmission, aeronautical navigation and other fields. The planning, management, coexistence, coexistence and effective utilization of frequency resources in this frequency band concern
