CASE STUDY: W IRELESS BACKHAUL OPTIMIZATION
CFN Services is a telecom infrastructure services
companyspecializing in wireless backhaul optimization, fiber, and
fixedwireless transport networks, data, infrastructure, and
services.
We created FiberSource , the industrys best and
mostcomprehensive backhaul infrastructure knowledge-base withover
550 fiber networks across 120 markets nationwide.
With fiber proximity data on more than 200,000 wireless sites,
including 80,000 tower and rooftopcollocation sites leased by the
top 50 tower companies, FiberSource enables efficient wireless
broadbanddeployment and optimization. FiberSource provides
visibility into existing fiber served sites and sites nearfiber
routes, including the wireline carriers who serve each site and the
wireless carriers collocated there.
BACKGROUND
A Tier 1 mobile carrier was operating a statewide network of
more than 1,000 cell sites interconnecting with 2primary mobile
switching centers (MSCs). The carrier was spending more than $15
million annually onlocal access transport services for backhaul
from the cell sites to the MSCs and interconnection from theMSCs to
the local telephone companys (LEC) access tandems. Planned 3G
network upgrades promised todouble T1 capacity requirements at more
than 600 cell sites.
BUSINESS CHALLENGE
Reduce leased network transport costs in the face of pending
capacity growth, while positioning the backhaulnetwork to support
backhaul for 3G broadband data services.
NETWORK SOLUTION
CFN analyzed the wireless carriers embedded access transport
circuits, costs, and growthrequirements at the facilities level
between the cell sites and the MSC, and between the MSC and the
publicswitched network. Leveraging its FiberSource design platform
and network optimization tools, CFN designedan optimized fiber
network that interconnected the MSCs and pushed interconnection
points with the LEC outfrom the MSCs to 7 strategically placed LEC
central office collocations.
Working with one of the leading optical equipment vendors CFN
and the vendor designed a turnkey opticaltransport platform to
displace existing DS1, DS3, and SONET circuits that were at or past
term. The plannedplatform displaced more than $8 million in gross
circuit costs annually from the LEC and delivered net savingsof
more than $6 million per year. In addition, the optical transport
platform was designed to deliver an aggregatecapacity of more than
4,000 T1s which included 25% excess capacity available for growth
at no additional cost.
The optical transport platform delivers 60% leased circuit cost
savings and 30% net transport savings. It alsoenables the wireless
carrier to double capacity on the platform for less than a 20%
incremental cost, while
seamlessly integrating TDM and Ethernet transport capabilities
at each network node and positions thenetwork for further
optimization via wireline and wireless technologies at the
edge.
CFNS offers a range of planning, deployment, and managed network
services to support wireless backhaulnetwork optimization. Services
range from direct fiber sourcing support, LEC collocation, and
interconnection toturnkey delivery, leasing, and management.
