4G premises: signal from 2 operators - WMCA

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

此指标展示了住宅及小型商业场所中，从四家移动网络运营商（EE、沃达丰、O2或Three）中两家所提供的可靠4G信号的占比。换言之，仅此比例的区域中，仅有一个网络可用。关于整体覆盖范围，请参阅所有运营商的覆盖指标。该数据由Ofcom编制，基于移动运营商提供的数据，并参照大不列颠测绘局（OSGB）坐标系统进行校准。场所覆盖范围的计算基于来自测绘局地址库（AddressBase）的邮政投递点。运营商产生的移动覆盖基于理论模型，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、作为繁华地区的道路行人以及在开阔空间中——这些都会影响覆盖范围。鉴于移动性能随时间的变化，该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，该文件提供的信息可能有助于识别不同地理区域中移动性能的差异。数据由LG Inform Plus提供支持，并自动于每月第三天检查新数据。
