New devices turn on and off within a blink of the eye. And similarly applications within those devices turn on and off instantly. Why should the users wait for several seconds when establishing their internet connection or downloading a web page? The key for instant user experience with the internet is proximity of the wanted data, high bandwidth and low network latency.
Gamers are especially sensitive to data delay, since their applications call for latencies below 10 milliseconds. Similarly many automated trading applications are highly sensitive to delay, transactions taking place in milliseconds and latencies causing losses of profits. Latency will have a major impact on emerging services and applications, such as mobile video communication, live video streaming and multi-player gaming – surely we’re going to see more and more emphasis being placed on real-time performance in mobile services in the future.
Low latency is an opportunity for network operators to change the game in content delivery by enhancing the customer experience of latency-sensitive applications. The evolution of the standards gives a promise on low latency networks. In general, an overall latency of 50ms is likely to be the benchmark in the coming years.
In today’s mobile networks, this 50ms figure is far from being achieved. However, measurements in LTE networks show significant improvements in latency because of high bandwidth and low latency technologies as the figure shows.
The new white paper about low latency networks shows how networks can be designed to achieve extremely low latency values to meet the requirements of new applications. The white paper is available on our Technology Vision page.
