<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 />
