SMEs and communications services

Ofcom undertakes research on the availability and experience of communications services for small and medium enterprises (SMEs) in the UK, defined as businesses with fewer than 250 employees. A survey of 1501 SMEs (0-249 employees) was undertaken using CATI (computer aided telephone interviewing). The survey data were weighted to be representative of the SME universe on size. Fieldwork took place between 9 May and 18 July 2016.

Mobile matters

To better understand the changing ways in which people use their mobile services, and the experience they receive, Ofcom has analysed crowdsourced data collected between January and April 2020 from around 200,000 Android devices across the UK.

In this report, we focus on the share of connections across wireless network technologies (2G, 3G, 4G, 5G, Wi-Fi), the success rate for mobile connections, response times and patterns in the ways people use their mobile phones. We also look at how these vary by factors such as location, day of the week and time of day.
