Executive Summary

A Tier 1 mobile carrier was operating a statewide network of more than 1,000 cell sites interconnecting with 2 primary Mobile Switching Centers (MSCs). The challenge was to reduce leased network transport costs in the face of planned capacity growth, while positioning the backhaul network to support 3G broadband data services. CFN analyzed the wireless carrier's embedded access transport circuits, costs, and growth requirements at the facilities level between the cell sites and the MSC, and between the MSC and the public switched network. Leveraging its FiberSource design platform and network optimization tools, CFN designed an optimized fiber network that directly connected the MSCs and pushed interconnection points with the LEC out from the MSCs to 7 strategically placed LEC central office collocations.
