Every now and then, a revolutionary technological advance comes along and changes the way we live. Li-Fi might just be the next one. Thanks to Prof Harald Haas from the University of Edinburgh, who has demonstrated that by modulating light in an LED bulb, data can be transmitted at a speed 100 times faster than Wi-Fi.
The technology, which could be commercially available in three to four years, will enable us to outfit our offices, malls or bus stations – just about anywhere that has lights – with LED bulbs that send and receive data and provide illumination at the same time. Li-Fi would also be more secure as light can’t penetrate walls, meaning your neighbours won’t be able to steal your bandwidth or eavesdrop on your communications.
The development comes as we mark another milestone in science – the centenary of Einstein’s theory of general relativity that showed how light was at the centre of the structure of space and time. It’s a reminder of the distance we have travelled in 100 years.

Key figures in the life of the fort
Sheikh Dhiyab bin Isa (ruled 1761-1793) Built Qasr Al Hosn as a watchtower to guard over the only freshwater well on Abu Dhabi island.
Sheikh Shakhbut bin Dhiyab (ruled 1793-1816) Expanded the tower into a small fort and transferred his ruling place of residence from Liwa Oasis to the fort on the island.
Sheikh Tahnoon bin Shakhbut (ruled 1818-1833) Expanded Qasr Al Hosn further as Abu Dhabi grew from a small village of palm huts to a town of more than 5,000 inhabitants.
Sheikh Khalifa bin Shakhbut (ruled 1833-1845) Repaired and fortified the fort.
Sheikh Saeed bin Tahnoon (ruled 1845-1855) Turned Qasr Al Hosn into a strong two-storied structure.
Sheikh Zayed bin Khalifa (ruled 1855-1909) Expanded Qasr Al Hosn further to reflect the emirate's increasing prominence.
Sheikh Shakhbut bin Sultan (ruled 1928-1966) Renovated and enlarged Qasr Al Hosn, adding a decorative arch and two new villas.
Sheikh Zayed bin Sultan (ruled 1966-2004) Moved the royal residence to Al Manhal palace and kept his diwan at Qasr Al Hosn.
