What actually constitutes a 5G  network is a bit nebulous at the moment, but the general consensus is  that it would be somewhere between 10 and 1000 times faster than current  4G LTE networks, with download speeds in the region of 100-1000  megabytes per second — fast enough to download a TV episode or movie in a  couple of seconds. The South Korean government hopes that by getting  ahead of the curve, national chaebols such as Samsung and LG — which  represent a significant portion of the country’s entire GDP — will have a  competitive edge when other nations get around to rolling out 5G.What exactly is  5G? That’s a very good question, and as it stands there’s no definitive  answer. The ITU, the organization that defines telecoms standards, has  only just started looking at the problem and is years away from a 5G  specification. Right now, 5G is essentially a catch-all term for the  next generation of very-high-speed mobile networks that are being  developed by various research groups around the world. There have been  very few actual real-world 5G tests. In mid-2013, Samsung set up a “5G”  wireless link capable of 1Gbps (100MB/sec) over two kilometers (1.2  miles) — but there are scant few details on how Samsung actually pulled  it off, and even fewer details of whether the test was actually  applicable to mobile applications (it sounds like Samsung used a big van  full of batteries and antennae).If things move quickly, we might  have a 5G standard by 2015 or 2016. The South Korean roadmap, following  the government’s $1.5 billion investment, wants to see a trial 5G  deployment in 2017, and a commercial service by the end of 2020. The  main barrier to developing a 5G standard, though, is finding a suitable  way of pushing gigabits of data through the air without interfering with  other wireless services and without burning through the battery.</blockquote>
