Online technologies are an integral part of many children’s lives. In 2017, the Children’s Commissioner for England identified shortcomings in online safety education and a number of stakeholders have called for action to increase ‘digital literacy’ in the UK.

5G is the next generation of mobile communications technology. It follows on from the previous generations of mobile technology, such as 3G and 4G. 5G is expected to improve on previous mobile technologies by providing faster, lower latency (response time) mobile broadband connections and being able to connect a greater number of devices to a mobile network in a particular area while maintaining good quality connections. 5G mobile broadband will be the first widespread application of the technology. However, in the longer term it may have applications in other sectors.
