Readers of this website will remember that we conducted an online survey to find out what our residents think about the mobile phone signal strength across Radyr and Morganstown.
201 responses were received - and they painted a fairly consistent picture with regard to signal strength.
The survey showed that, in general, signal strength across Radyr and Morganstown can often be described as poor or terrible.
We have sent our survey report to Eleanor Marks, Ofcom's Director for Wales. You can read our letter to Eleanor here - and you can read our full report here.
We will let you know what Eleanor has to say.
