信息产业部最近以信部(1998)649号文件发布《关于PHS和DECT无线接入系统共用1.9GHz频段频率台站管理规定的通知》,其主要内容如下。根据原国家无委《关于2000MHz频段部分地面无线电业务规划及有关问题的通知》(国无管[1996]22号),1900—1920MHz频段用于无线接入系统TDD方式。目前,符合上述频率规划的有数字无绳电话系统PHS和DECT两种技术体制。为保证这两种不同系统能共用同一频段并正常工作,防止相互产生有害干扰,现将PHS和DECT系统的频率指配、台站审批等有关问题,具体规定如下: 一、频率分配
The Ministry of Information Industry recently released the Circular on the Administration of PHS and DECT Wireless Access Systems Sharing 1.9 GHz Band Frequency Stations Based on the Document No. 649 of the Ministry of Information Industry. The main contents are as follows. According to the original State No Commission “on the 2000MHz band part of the terrestrial radio service planning and related issues notice” (stateless [1996] No. 22), 1900-1920MHz band for wireless access system TDD mode. Currently, in line with the above frequency plan there are digital cordless telephone system PHS and DECT two technical systems. In order to ensure that the two different systems can share the same frequency band and work normally and prevent harmful interference from each other, the related issues such as the frequency assignment of PHS and DECT systems and station approval are specified as follows: I. Frequency Allocation
