SK Telecom and Nokia achieve 2ms latency on an LTE network

Lowering latency is key to several emerging mobile use cases including high quality mobile video and autonomous vehicles. Much of the work in this area is related to 5G, but SK Telecom and Nokia have made a breakthrough on an LTE network, reducing latency from current 4G levels around 25ms, to just 2ms. The proposed specification for 5G calls for ultra-low latency of 1ms or less, though this is a challenge which many think will not be met until a future generation of the standard, except for very small packets (the smaller the packet, the lower the latency). However, getting to 2ms on a 4G network raises hopes that the 3GPP specs may not be over-optimistic after all. They achieved…
