I live in Kaiapoi and was standing under the Telecom cellular tower.
I looked at the signal strength on my CDMA phone which showed only 2-3 bars. I would have thought, given the proximity to the tower, I should be getting a full strength signal.
Also noticed is that some towers seem to have 2 types of antennae which I have assumed is for the 2 types of networks Telecom has - correct me if I'm wrong.
