BT announced today that it has completed its project to install 500,000 wi-fi hotspots across London, with the launch of over 100 new hotspots along the River Thames.

The hotspots give Londoners, visitors and commercial and private river users access to the internet at locations such as the Cutty Sark in Greenwich, The London Eye, Waterloo Pier and London Bridge Pier.

BT made a public commitment in September 2011 to have half a million hotspots in place for the London 2012 Olympic and Paralympic Games, as part of its role as official communications services partner.

Although BT only announced the news today, a spokesperson told Techworld that the company completed the network two weeks ago - in time for the Olympic opening ceremony.

Over the last three months, almost 200,000 hotspots have been added, giving a huge boost to connectivity in the capital. Hotspots can be found in high street shops, hotel chains, independent businesses and homes, and outdoors in Westminster and Waltham Forest.

The company has also installed a public high density Wi-Fi network in the Olympic Park, consisting of 1,000 access points across nine venues, including the Olympic Stadium, the Aquatics Centre, the Velodrome and across all public areas of the Olympic Park in East London.

The company said that more Wi-Fi access is good news for commuters who have been urged to work flexibly or remotely to ease congestion and keep London moving during the Games.

"We’re giving Londoners and visitors as many places as possible to get online, keep in touch, work and share their experiences of the exciting events happening across London.” said Andy Baker, CEO of BT Wi-Fi.

Access to the network is free for BT broadband customers, whilst those wishing to purchase Wi-Fi vouchers will be able to do so online.
