Looking at the Crewe and Nantwich predicted coverage, it's hard to say how many masts they might be upgrading could only be 1 or 2 prominent ones in each area, or if the actual coverage will be smaller, they've certainly made a mistake on the mast in market Drayton as it makes it look like a large area is covered when in fact it's not, my guess is this is the predicted coverage area of the main mast in the town on the water tower or both masts, but this one couldn't be upgraded for some reason yet (only single carrier 3g at the moment so must need new backhaul) just nobody's told the map people yet. back to Nantwich/Crewe, even with fringe coverage from these towns and not the nearest masts the coverage and speeds will be much better in the rural areas where I live then those presently on three and maybe even EE which goes from feast to famine on the hill sides and where orange masts still reign supreme, which will give me and my contact food for thought..
