Superfast South Yorkshire (SFSY) is a partnership of Barnsley, Doncaster, Rotherham and Sheffield Local Authorities and South Yorkshire Mayoral Combined Authority. It was established in 2014 to improve the digital infrastructure throughout South Yorkshire.

The first phase of roll-out was delivered in partnership with Openreach completed in September 2019. It saw almost £27m funding invested to reach an additional 95,000 premises. The second phase is currently in delivery and has brought gigabit capable broadband on the Openreach network to an additional 6,000 premises. Over 100,000 residents and businesses have directly benefited from the programme. 

In 2022 Superfast South Yorkshire partnered with South Yorkshire Mayoral Combined Authority to deliver part of the Digital Infrastructure Strategy. This Digital ‘Infrastructure’ Strategy is part of, and covers, one of three key areas of activity critical to providing a strategic approach to addressing the digital agenda across South Yorkshire in an integrated way.

What is 5G

5G is the newest generation of mobile networks following on from 3G and 4G offering faster and more reliable connections along with increased capacity meaning more devices can be connected in an area at the same time. 

This technology is future ready and will enable the smart towns and cities of the future transforming the way we communicate, manufacture and travel to list a few. 

5G and Health

Mobile phones and mobile masts transmit and receive radio waves, which are a type of electromagnetic radiation. Importantly, this type of radiation is classed as mainly harmless, or in scientific terms, non-ionising when used within guidelines, just like our TVs, remote controls, home Wi-Fi and so on. It is widely recognized that the strength of the signals is extremely weak and therefore does not have enough energy to cause adverse health effects. 

You can learn more about the benefits, businesses applications, and health concerns associated with 5G on the Mobile UK website.
