The Minitel, an internet forerunner, allowed users to check the news and make restaurant reservations. Gerard Thery, the telecoms engineer whose Minitel project brought internet-style communications to France long before other industrialised countries, has died aged 88, officials said Monday. Thery, who oversaw the development of the Minitel ahead of...

This map shows how Optus infrastructure, such as the pictured Dixon’s Creek Site in Victoria, is assessed for fire threat or building loss potential. Each coloured dot shows the level of hazard that location presents to the Optus infrastructure in the centre of the image. Locations are analysed for ember,...

Without spectators, TV crews will have to innovate at Aomi Urban Sports Park, the main venue for 3x3 basketball during the Tokyo Olympics. There'll be no fans in the stands, and less media on the ground, so when it comes to covering the Tokyo Olympics, broadcasters are relying on technology...

Deep streams of data from Earth-imaging satellites arrive in databases every day, but advanced technology and expertise are required to access and analyze the data. Now a new system, developed in research based at the University of California, Berkeley, uses machine learning to drive low-cost, easy-to-use technology that one person...

A vehicle that remains continuously connected even when in remote areas is being road tested in Cornwall in the south west of the UK. The test vehicle will use ubiquitous communications technology to switch seamlessly between 5G and satellite networks as required. The technology was developed by Darwin Innovation Group,...
