一种专用广域寻呼系统，提供现场寻呼系统的灵活性、多功能性和速度，但覆盖范围更广。专用广域寻呼系统的最低性能特征和相关测量方法。通过使用更高的发射机功率和天线位置，以及指定的接收机灵敏度，实现了具有扩展自由场范围的现场寻呼系统。它可以使用分时来增加虚拟可用频道的数量。建议的分时系统是一个自由运行的系统，需要最小的开销，并提供最小的净损失- 广播时间。该系统将在高频VHF或UHF频率范围内工作。涵盖的设备类型:基站发射机/接收机/收发机、袖珍接收机。潜在客户包括急救服务、医院和制造业，可能位于覆盖区域内的各个地点。连接到PSTN接口的设备可能需要额外的标准/规范。本ETS和ETS 300 741旨在成为一个协调标准，其参考文献将在参考EMC指令的欧洲共同体官方公报中引用。

A private wide area paging system which provides the flexibility, versatility and speed of an on-site paging system but covering a wider area. Minimum performance characteristics and related methods of measurement for private wide-area paging systems. On-site paging systems with an extended free field range achieved by using a higher transmitter power and antenna location, as well as a specified receiver sensitivity. It may use time sharing in order to increase the number of virtually available channels. The time sharing proposed is a free running system that requires minimum overhead and supplies minimum loss of net-airtime. The system will work in the high band VHF or UHF frequency range. Types of equipment covered: base station transmitters/ receivers/ transceivers, pocket receivers. Potential customers include emergency services, hospitals and manufacturing industry that may be located at various sites within the coverage area. Additional standards/specifications may be required for equipment inteded to interface to the PSTN. This ETS, together with ETS 300 741, is intended to become a harmonised standard, the reference of which is intended to be cited in the Official Journal of the European Communities referencing the EMC Directive.
