LiFi – Lights that have Wifi?

Marcus Bronzy is at Mobile World Conference in Barcelona this week and he got to witness something really really cool! Our internet connectivity is about to be revolutionised! With LiFi – a type of technology that will allow internet connections via light. Yes light. It’s quicker than wifi too! When we said Lights we mean any lights, so thats lights that are in our car headlights, street lights and the lights in our homes.

LiFi: How does it work?

LiFi enabled LED lights modulate illumination levels and send data, just like morse code. Thus sending it to your device. The current (light) can be modulated at extremely high speeds, this in turn can be detected by a light detector on your device and the current re-converted into an electrical current, therefore carrying data.

You will still need an ethernet connection to connect to the internet, but once you’re all set up, you’re good to go to get wireless internet from light!

As routers are that gives you 100mbs a second, lights are much faster as each LED bulb has a maximum of 42mbs EACH. So if you have 10 LED bulbs in your area, that’s a total of 400mbs! What makes it faster is that data is sent and received at the same time!

LiFi doesn’t use radio frequencies, it uses the light spectrum which allows for a whole lot more data to be carried. 1000x more bandwidth available to users to be exact!It doesn’t affect radio frequencies either so you can use it in hospitals, airplanes and places like chemical plants. Safely.

This technology will be an integral part of wireless networks in the future!

LiFi: Security

LiFi is limited to the area in which the light illuminates and touches. So unlike WiFi your signal will remain hidden to anyone outside of the illuminated area! Want even more security? Simply close the door or draw the curtains to protect your network from hackers! The LiFi lights are fully networked and each light can ‘speak’ to each other, each with their own separate IP address! Why would the lights need to speak to one another? So you’re able to move around your home or office space and not lose connection!

Free WiFi Cleaning?!

Maybe you should read the T’s & C’s of Free WiFi, as recently 22,000 people are now legally bound to 1000hrs of community service. Which includes, but not limited to cleaning toilets at festivals, scraping gum off the street and “manually relieving sewer blockages” – Sounds horrifying!

Whether or not these people actually completed their smelly tasks is anyones guess but, Manchester based WiFi company ‘Purple’ slotted the cheeky terms into their T’s & C’s for 2 weeks to highlight the importance of T’s & C’s and raise the awareness that people should have when signing up to free wifi. They also offered a prize if you raised it to them and only 1 person highlighted the cleaning contract to them.

Not the first time this has happened, in 2014 Cybersecurity firm F-Secure done the same, but this time, free WiFi was in exchange of their first born.

While Terms and Conditions are legally considered contracts and binding, it is argued that the inability to negotiate such terms violates common law practices, thus leaving them void.

Facebook now offers help to find free WiFi for you wherever you are

Facebook is launching a new feature to help find free WiFi worldwide

Facebook has been in the testing phase for this new feature for the past 12 months, rolling it out only in certain countries on Apple devices to see how well it worked, but now they have confirmed that this feature will be available on both iOS and Android platforms.

This is a dream come true for those on low data packages or for the individuals who often find themselves without network.

To access this function you need to go to the ‘More’ tab in the mobile app and then click on ‘Find WiFi’.

Businesses in the area will need to opt in to make their WiFi available to the public through Facebook, but Facebook still dominates social media in terms of monthly users so it could be beneficial for the businesses who choose to opt in and provide this service.
