Telephonica and Vodafone have started an upgrade of their mobile phone network in west York.
The programme involves upgrading their local phone masts and base stations.
Local Councillors are being consulted on the changes.
One – on Acomb Wood Drive – has already been subject of some comment as the height of the mast is being increased significantly.
Most of the others are more simple equipment replacements which the companies say will improve 3G phone coverage in the area.
Cllr Andrew Waller is keeping an eye on the plans. He has already pointed out that the location of the phone equipment outside the Acorn Rugby Club car park on Thanet Road, obscures sight lines for those exiting. He hopes that any new equipment might be set back a little to address this issue.
