Say hello to li-fi

Say hello to li-fi, the new wi-fi


Move over wi-fi, there’s a new kid on the block


This week, a new method of delivering information online was tested in Tallinn by Estonian start-up, Velmenni.


The technology, namely li-fi is able to provide internet access more than 100 times faster than the regular wi-fi we know and love, boasting top speeds of up to 1GB per second. Lab tests suggest this could further increase to a massive 224 GB per second!


How does li-fi work?

Li-fi requires an internet connection, an LED bulb or other enabled light source and a photo detector.


This innovative technology enables data to be encoded into pulses of light,  similar to what happens in TV remote controls. The light spectrum is around 10,000 times bigger than the radio waves used for typical wi-fi, meaning we could potentially wave goodbye to those pesky low coverage hotspots.

The pros and cons of li-fi

Li-fi is still in the early development stages but it’s likely to become accessible to consumers within three years. Here’s what you need to know:


  • Li-fi does not interfere with other radio signals, meaning it could be used on aircrafts or near hospital equipment  – something we’re not used to with wi-fi.
  • Wi-fi radio waves are in short supply, but the light spectrum is much bigger, so it should never run out




  • Li-fi technology cannot currently travel through walls which is highly unpractical. However, it could work well as a supplement in large wi-fi networks or areas where wi-fi is dangerous.


  • The light signal is interfered by direct sunlight, meaning that outdoor useage is not possible.




Windows 10 automatic upgrade

Windows 10 Automatic Upgrade

Microsoft has just announced that Windows 10 will be automatically installed to all devices as of early 2016.

Up to now, Windows 7 & 8 users have received numerous (annoying) pop-ups giving them the option to upgrade to Windows 10 through a registration process. But this is all set to change. For the rest of this year, the Operating System upgrade will be listed as an ‘optional update’, and then as of 2016 it will be re-categorised to ‘recommended update’ which will automatically install itself – giving users very little freedom of choice.

It will be possible to opt out of the Windows 10 upgrade but Microsoft insists that this may put your device at risk of cyber threats.

How to Cancel Windows 10 Upgrade

As with all upgrades, it will possible to return back to your previous version of windows within 31 days if you wish. All you’ll need to do is click on Settings > Updates & Security > Recovery > Uninstall Windows 10. This will restore your system to its previous version of Windows.

How to avoid upgrading to Windows 10

To avoid falling foul of this mandatory upgrade, you should adjust a few settings ahead of the automatic upgrade changes that are coming in 2016. Here’s how:

Hit the Start button and go to the control panel, then click updates or Windows update for Windows 8 users and select “change settings” from the left hand task bar. This will take you to a new window and from the “Important updates” section, and from the drop down menu, select “Check for updates but let me choose whether to download and install them”. By choosing this option, you will have full control of the future upgrades and updates your device is installing.
