 The RFI is believed to be for a 4G+ mobile phone service which will bridge the gap between 4G and 5G. It is thought that the signal provides coverage to the Manchester metropolitan area, and this is seen at Pickmere and Darnall too. The RFI is believed to be for a 4G+ mobile phone service which will bridge the gap between 4G and 5G.
