As the internet is expanding rapidly and new households are being connected to the internet on a daily basis, the demand for new technologies to facilitate this rapid expansion is growing as well. The old architecture of the internet had several drawbacks such as IPv4. However, we have come a long way and practically every place has wireless internet (Wi-Fi). The advantages of Wi-Fi over cable networks are obvious and are the catalyst for the surge in mainstream adoption of wireless technology worldwide. For example, Taipei is currently implementing a free public Wi-Fi network for the city.
China is a rapid rising economy at the moment and, as a result, its huge amount of citizens are moving to urban settings in a fast pace. These demographic changes put a huge amount of stress on governments, both national and local, to facilitate this transformation adequately. Although a large part of China is already making use of the internet, it still is very limited in terms of amount of connections in smaller cities and internet speed. Moreover, let’s not forget the great firewall of China blocking a large amount of content on the internet to Chinese society. Nevertheless, scientists at China’s Fudan University have managed to create a futuristic solution: internet emitting light bulbs.
This technology, dubbed Li-Fi, can at the moment provide 4 computers per bulb internet at speeds of 150 mbps which is much higher than the average broadband connection in China. As you can see, this new technology might provide China and other countries new ways for internet adoption. Moreover, it could provide companies huge investment costs of large internet servers and router networks within the firm; rather, it could replace all the light bulbs with Li-Fi ones as light is essential within society.
To me, these are interesting developments and could lead to a more worldwide adoption of the internet, creating an even more connected world. Also, imagine the possibilities of this techology such as Li-Fi streetlighting. Can you think of other usefull solutions?
