Half a million Wi-Fi hotspots will be in place across London in time for the start of the London 2012 Olympic and Paralympic Games.

Improved Wi-Fi access across the capital is certainly good news for the commuters that will be working flexibly or remotely during the Games to reduce congestion and time wasted commuting.

As well as being able to utilise the wireless network around London, users will also have access to the 3G network, allowing them to download and upload as much data as they wish without worrying about surpassing their data limit.

Mayor of London Boris Johnson said the creation of 500,000 Wi-Fi hotspots is "fantastic news" for the visitors coming to London over the summer, but noted it is "even better news for London's businesses".

Gerry Pennell, LOCOG chief information officer, said: "The 2012 Games will be a truly digital Games and this enhanced Wi-Fi coverage is giving people additional opportunities to get online, keep in touch and share their experiences during this exciting time."

Access is free for BT broadband customers and included in contracts for millions of Android, iOS and other smartphone devices through BT agreements with UK and international network providers.
