5G is not about speed

The breakthrough was made despite speed not being the main focus of the research being carried out at the University of Surrey’s 5G Innovation Centre (5GIC), which was founded by industry partners Huawei, Fujitsu, EE, Aircom, BT, Samsung, Telefonica, Vodafone, BBC, Aeroflex and Rohde & Schwarz

“We can provide the highest-ever speed wirelessly. Two hundred to 800 times faster than the fastest time in 4G – 0.1 terabits to 0.8 terabits per second,” said Professor Rahim Tafazolli, head of 5GIC, at an event in London today announcing the ‘vision’ for 5G.

The 0.8 terabit speed was achieved with a bandwidth of 100 megahertz and tested with 1024×1024 antennas, and is “implementable today”, Tafazolli said. However, he pointed out that factors such as available spectrum and 100 MHz bandwidth will determine the actual speed delivered outside the research lab.

Tafazolli insisted that, despite the breakthrough, “speed is not the differentiator” between 5G and previous network generations, 2G to 4G.

According to the researchers, the 5G network will intelligently understand the demands of the user depending on the context, and allocate resources to ensure that the demand is met instantly.
