The experts guide to 4G


4G: the next step in super-fast mobile internet services. It’s a term we frequently hear bandied about. But what exactly is it? How does it work, and why should we use it? Here we take a closer look at the ins and outs of 4G.

What is 4G?

4G stands for ‘fourth generation’. It refers to mobile network technologies that enable smartphones and other portable devices to connect to the internet. Superseding 3G, which introduced the concept of mobile internet, 4G is simply the next move towards faster, more efficient services.

Since launching in the UK in 2013, 4G is offered alongside 3G services – though will inevitably replace it when networks expand. Depending on service provider, 4G can offer significant download speeds of around 5-7 times faster than 3G.

How does it work?

To understand how 4G works, it helps to understand the technology behind it.

  • Like 3G, 4G wireless networks are basically radio systems which communicate information. With 4G – and because of advances in technology – more digital data can be squeezed into each signal, maximising the speed and efficiency of the network.
  • Both 3G and 4G networks are IP (Internet Protocol)-based, meaning they use standard communication protocol to send and receive data. With 4G, the ideal is an all-IPstandard, meaning all data, including voice data, can travel without being scrambled or corrupted.
  • 4G systems are more sophisticated than 3G. They can independently overcome problems thanks to sensors and advanced software, such as crashes resulting from spikes in demand.

What this means is all-round enhanced mobile internet services, much better suited to dealing with the ever-expanding demand for on-the-go multimedia data.

Why should we use it?

4G makes everything on our phones and mobile internet devices work that much smarter. The benefits?:

  • Improved browsing speeds – whether you’re shopping or paying bills, you can do it significantly faster
  • Faster downloads – from videos to music, apps and podcasts
  • Less buffering when streaming – less interrupted viewing or listening on YouTube or Spotify
  • Better quality video calling – meaning less pixilation and fewer delayed responses on Facetime and Skype
  • Quicker responses to online commands – enhanced play capabilities for online gaming
  • More effective apps – quicker status updates on Facebook and Twitter, swifter map app responses

In short, 4G is ideal for those who want to enjoy all the benefits of multi-media mobile internet in their pocket. And, if you are looking to switch to 4G, there are some great offers out there, many with data plans comparable to 3G – such as that offered by Lycamobile.

The future of 4G

4G is still growing, but the benefits are already huge. The natural progression of 3G, 4G is the high-speed mobile technology of today and tomorrow.
