12 months on, the data shows a significant move towards 4G, providing very fast internet access. Between January and March 2017 9.56M data samples were collected, and they show 4G availability (from any operator) increasing from 52% of locations measured to 74%. When compared with data collected between May and July 2016.

The availability of mobile data connectivity in the Greater Cambridge area has also improved and overall user experience is better, although there are still significant notspots in some areas. However, the proportion of locations measured which have no or only weak data-connectivity available (from any operator) has dropped from 19% to 12%. 

The amount of qualitative and quantitative data secured enabled us to hold meetings with various operators, including EE, Three and Vodafone, all of whom accepted that the data was accurate and shared their plans to resolve the identified notspots by early 2018. We will be meeting with the operators again at the end of 2017 to ascertain progress against agreed objectives.
