4G premises: signal from 3 operators - WMCA

This metric shows the proportion of residential and small business premises with a reliable 4G signal from three of the four mobile network operators (EE, Vodafone, O2 or Three). ie, for this proportion of the area only one network is available. For overall coverage see all operators metric. 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.

本指标展现了四家移动网络运营商（EE、沃达丰、O2或Three）中，拥有可靠4G信号的住宅和中小企业场所的比例。换言之，该比例覆盖的区域仅有一家网络可用。欲了解整体覆盖范围，请参阅所有运营商的覆盖指标。此数据由Ofcom机构根据由移动运营商提供的数据生成，并与英国大地测量局（OSGB）坐标系统进行对照，场所覆盖范围计算基于来自大地测量局地址数据库的邮政投递点。运营商生成的移动覆盖数据基于理论模型，并通过实际性能的测量进行校准。然而，消费者在多种不同的场景中使用移动电话——室内、室外、移动中、车内、作为步行者在繁忙地区的道路上以及广阔的开阔空间中，所有这些都会影响覆盖效果。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，本文件提供的信息可能有助于识别不同地理区域移动性能的差异。数据由LG Inform Plus提供支持，并自动于每月第三天检查新数据。
