Türk Telekom’s 5G and AI development

Vodafone is running a new trial across the River Severn catchment area aimed at using its mobile network to predict short-term rainfall.
The trial functions by leveraging the inherent physical properties of wireless communications. Electromagnetic spectrum signals – especially at higher frequencies – can be attenuated by rain, meaning that signal strength can be a useful indicator of rainfall.
Vodafone’s partner, Wireless DNA, will monitor and analyse signal information from the Vodafone’s microwave links between masts, allowing for a more accurate short-term forecasting, also known as ‘nowcasting’.
This data, in turn, will be passed to the River Severn Partnership with the goal of supporting early warning systems and flood defence planning.
According to Vodafone, the data gathered from the mobile network will be more accurate that radar and more detailed than weather stations.
“Storms and extreme weather are becoming more frequent and destructive. Working with River Severn Partnership, we can use our cutting-edge technology to provide greater insight on weather forecasting and help mitigate the impact of extreme events,” said Nick Gliddon, Director, Vodafone Business UK. “This example shows how, through innovation, our mobile network can have a real impact on not just the lives of residents who live and work in the River Severn area, but for communities across the UK.”
Using wireless networks as sensors to monitor the surrounding area is not a new concept. In-home Wi-Fi sensing technology, for example, is already on the market, monitoring movement in the home to detect unwanted intruders or contacting emergency services in the event an elderly customer suffers a dangerous fall.
Using a mobile network for this purpose, however, has largely been a topic reserve for 6G. Integrated Sensing and Communications (ISAC) is one of the key developments of the new technology, allowing for far greater detail than traditional radar deployment.
At Mobile World Congress this year, Vodafone itself demonstrated a planned ‘network-as-a-radar’ use case, suggesting that its network could identify objects like birds or drones from 3km away. This, the company said, could provide invaluable data to locations like airports, ports, and other sensitive locations.
