Introduction<br />
� <strong>Backhaul</strong> plays a vital role <strong>in</strong> mobile networks by act<strong>in</strong>g as the l<strong>in</strong>k<br />
between Radio Access Network (RAN) equipment (Eg: radio<br />
basestation) and the mobile backbone network.<br />
– This means that backhaul is able to transport mobile data from the end<br />
user to the <strong>in</strong>ternet (or similar network), mobile networks and traditional<br />
telephone networks.<br />
� The rapidly evolv<strong>in</strong>g telecoms marketplace has meant that mobile<br />
operators are fac<strong>in</strong>g a significant spike <strong>in</strong> bandwidth demands <strong>in</strong> the<br />
backhaul due to-<br />
– The proliferation <strong>of</strong> 3G-based data services and<br />
– The emergence <strong>of</strong> high-speed air <strong>in</strong>terface enhancements such as High<br />
Speed Packet Access (HSPA).<br />
� At the same time, backhaul network operators are be<strong>in</strong>g required to<br />
significantly reduce operational costs <strong>in</strong> order to compensate for<br />
decl<strong>in</strong><strong>in</strong>g Average Revenue Per <strong>Use</strong>r (ARPU) and to compete with a<br />
host <strong>of</strong> new competitors and technologies.<br />
� Operators are also required to protect (or sufficiently emulate) core<br />
legacy services such as voice, which still account for a substantial<br />
share <strong>of</strong> revenue.
