We have all been there - seen a new mobile phone model and been convinced that it is the answer to all our problems and that we will never need to upgrade again. While 4G does promise a lot, it is worth stepping back and taking a more realistic view.
If 3G were to cut out completely I wonder how teenagers would communicate? After all without free WI-FI that group of teenagers I saw would have just been sat on a bench, not talking to each other. Oh the joy.
Most people never go anywhere without their mobile these days and there even exists a name for those who experience anxiety when they are without their phone: nomophobia. What's more, O2 claim mobile usage abroad is growing by 100% each year.
Derek McManus, CTO of O2 UK said that: "watching a YouTube video on a smartphone uses the same capacity on the network as sending 500,000 text messages simultaneously." 4G networks are being designed to accommodate this demand.
