4G premises: signal from all operators - WMCA

This metric shows the proportion of residential and small business premises with a reliable 4G signal from all four mobile network operators (EE, Vodafone, O2 or Three). It has been produced by Ofcom, using data provided by mobile operators referenced against the Ordnance Survey of Great Britain (OSGB) Coordinate System, premises coverage is calculated from the postal delivery points taken from the Ordnance Survey AddressBase database.  Mobile coverage produced by operators are based on theoretical models, calibrated using measurements of actual performance. However, consumers use mobile phones in many different situations - indoors, outdoors, on the move, in cars, as pedestrians along roads in built up areas and in wide open spaces all of which can affect coverage. Due to variations in mobile performance over time, the file should not be regarded as a definitive and fixed view of the UK's mobile infrastructure. However, the information provided in this file may be useful in identifying variations in mobile performance by geography.Data is Powered by LG Inform Plus and automatically checked for new data on the 3rd of each month.

本指标展示了所有四家移动网络运营商（EE、沃达丰、O2或Three）提供的可靠4G信号在住宅和小型商业场所中的比例。该指标由英国通信管理局（Ofcom）编制，数据来源于移动运营商，并参照大不列颠测量规范坐标系（OSGB）进行校准。场所覆盖范围的计算基于来自测量规范地址数据库的邮政投递点。运营商生成的移动覆盖范围基于理论模型，并通过实际性能的测量进行校准。然而，消费者在不同情境下使用移动电话——室内、室外、移动中、车内、繁华地区的道路行人以及广阔的开放空间，这些都会影响覆盖范围。由于移动性能随时间的变化，本文件不应被视为英国移动基础设施的最终和固定视图。尽管如此，文件中提供的信息可能有助于识别不同地理区域的移动性能差异。数据由LG Inform Plus提供支持，并自动于每月第三天检查新数据。
