<strong>Why</strong> <strong>Latency</strong> <strong>Matters</strong> <strong>to</strong> <strong>Mobile</strong> <strong>Backhaul</strong><br />
<strong>Mobile</strong> Industry Landscape<br />
The <strong>Mobile</strong> industry is changing rapidly, as it evolves from 2G <strong>to</strong> 3G and on<br />
<strong>to</strong> 4G networks. This evolution is driven by the need <strong>to</strong> provide better<br />
performance in three main areas:<br />
− Provide subscribers with higher data rates<br />
− Support a wider variety of end user applications<br />
− Reduce the latency of the mobile network<br />
Increasing sales of 3G smartphones, USB modems, tablets and PCs with<br />
built in wireless radios is pushing data traffic on mobile networks <strong>to</strong> record<br />
levels. While email, social networks and Internet browsing are very popular<br />
among nomadic users, the deployment of mobile broadband services has<br />
the biggest impact on network traffic. In rural areas, mobile networks are<br />
often the only way <strong>to</strong> support applications his<strong>to</strong>rically delivered over<br />
copper based networks. Video streaming is a major contribu<strong>to</strong>r <strong>to</strong> the boost<br />
in traffic, with the success of Internet services such as YouTube and<br />
DailyMotion. The latest Cisco Visual Networking Index forecasts<br />
unprecedented global mobility demand.<br />
