Free registration required

Executive Summary

The rapid increase of the number of mobile subscribers as well as the deployment of 3G technologies are putting strain on mobile backhaul OPerational EXpenditures (OPEX) which amount to 20-40% of total mobile operator's OPEX due to their reliance on T1/E1 copper lines. For these reasons, the current backhaul systems, a term commonly used to describe connectivity between base stations and radio controllers, are increasingly integrating more cost-effective, packet switched technologies, especially Ethernet/Internet technologies. In addition, Wi-Fi andWiMAX are emerging as promising backhaul solutions and initial findings have demonstrated their feasibility.
