4G premises: signal from 1 operator - WMCA

This metric shows the proportion of residential and small business premises with a reliable 4G signal from one 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.

本指标展现了住宅及小型商业场所中，来自四家移动网络运营商（EE、沃达丰、O2或Three）之一可靠4G信号的占比。换言之，仅此比例的区域中，仅有一种网络信号可用。欲了解全面覆盖情况，请参阅所有运营商的指标。该数据由Ofcom编制，依据由移动运营商提供的数据，并与英国（OSGB）坐标系统中的测量数据进行对比，场所覆盖范围通过从《英国测量局地址数据库》中提取的邮政投递点进行计算。运营商生产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，消费者在多种不同情况下使用移动电话——室内、室外、移动中、车内、作为繁忙地区道路上的行人以及在开阔的空间中，所有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且固定视角。尽管如此，本文件提供的信息或许有助于识别地理区域间移动性能的差异。数据由LG Inform Plus提供支持，并自动于每月第三日检查新数据。
