Vodafone are using the information and data they’ve gathered to establish what works are needed to resolve the problem, and a timescale for these.

They identified several mobile phone masts across East Anglia needing their radio frequency power increased, as shown on map below:

Increasing the radio frequency means the mast covers a wider area, reducing ‘black spots’. But it must be done slowly – too much too soon can cause other problems.

Members in North East Norfolk should be seeing improvements in signal. 

Vodafone’s Service Optimisation team have made changes that have had a dramatic impact on dropped call rates across the cluster masts shown in red on the map below. This cluster of sites had shown a larger average drop call rate compared to others in the area.

The graph below shows volume of recorded service drops being around 4 to 5% on 21st May, latest correction adjustment occurred 4th July. From 5th of July onwards you can see the recorded drop rate significantly reduces to 0.5%. There will always be some dropped calls in a network just based on the “mobile” nature of users and devices. 0.5% is considered very good given seasonal impacts, building interference etc.

Vodafone anticipate phase frequency increases will be completed by the end of July.
They will also schedule further drive testing to measure improvements from power increases around the area.

The signal faults you’ve reported have been key in getting the network to look at these Member locations.
It’s important you continue to tell us about service drops, using our Report Phone Signal Issues form. This will enable us to keep up the analysis and required improvement work.
