The exploding growth of smartphones and other mobile data devices is

driving huge increases in demand for wireless bandwidth. New 4G Long

Term Evolution (LTE) services provide greater bandwidth for mobile

devices and will compete with residential broadband services. The 4G

LTE high-speed data technology is driving cell sites from traditional DS1

copper to ber-optic Ethernet based transport. For these reasons, there

is a growing business opportunity for independent local service

providers to deliver mobile backhaul network services at cell towers. In

many areas, often underserved rural locations, large wireless operators

and telecommunications carriers are seeking to expand their coverage

footprint, giving local service providers the opportunity to step in and

offer a mutually benecial business partnership to provide cost-effective

backhaul infrastructure on a rapid deployment schedule.

Typical Network Design

Small local carriers typically require networks that will connect one or

more Mobile Technology Switching Ofces (MTSOs), one or more Central

Ofces (COs) and a number of cell tower sites. The example design

below is based on an actual deployment for a local service provider in a

rural town in Alabama.

This network is based around an OC-48

optical backbone network ring,

connecting several COs. At each CO is a

hub, providing connections to individual

cell towers in various locations, as well as

one connection to a large carrier’s MTSO.

The Fujitsu FLASHWAVE® 4500

Multiservice Provisioning Platform

provides the high-volume connection

point at the carrier’s MTSO, and

FLASHWAVE 4100ES Packet Optical

Networking Platforms connect the cell

towers to the backbone.

Transitioning networks

The mobile communications environment is in a period of

transition, as data services (such as GPS navigation systems,

smartphone apps and mobile streaming audio/video) become

more prevalent. With the advent of 4G LTE network technology,

it becomes necessary to support mobile trafc in an all-Ethernet

environment. At the same time, wireless operators still have the

need to support older types of communications technology, such

as (Time-Division Multiplexing) TDM and Synchronous Optical

Networking (SONET). Ultimately, all network communications

will take place in an “all-packet” environment as Ethernet

technologies become universal.

Key strengths of Fujitsu Optical Networking Platforms

Fujitsu FLASHWAVE® optical networking equipment leads

the market because of its reliability, exibility and

performance. Several features of the FLASHWAVE

platforms make them particularly good choices for

backhaul deployments:

•  Scalability – Service providers value the ability to

expand their networks rapidly in response to growth in

their customer base, or to capitalize on new business

opportunities. The Fujitsu FLASHWAVE 4500 and 4100

ES systems are easy and economical to expand without

disrupting existing services.

•  Supporting new and older, “legacy” services – The

FLASHWAVE 4500 and 4100ES platforms support

transitioning networks as they migrate from traditional

TDM to new Ethernet-based services. The FLASHWAVE

4100 ES is also engineered to support an all-packet

service environment.

•  Environmentally hardened – The FLASHWAVE 4100 ES

is optimized for outside-plant cabinet deployments as

well as in indoor rack or cabinet settings.

•  Centralized management – NETSMART element

management provides centralized point-and-click

manangement for all FLASHWAVE platforms.

•  Flexible voltage operation – including +24 V DC and –48 V DC.

What is Mobile Backhaul?

Mobile backhaul and cell-tower backhaul are terms that refer to the

land-line, “wired” portion of mobile communication. Only the rst and last

leg of mobile network trafc travels on the airwaves, between the sender or

recipient and their nearest cell tower or wireless connection. The remainder

of the communication occurs mainly on the wired network between the cell

tower and Mobile Technology Switching Ofces (MTSOs). Some cell tower

trafc is transported to hub cell sites using microwave line of sight

technology.

Mobile and cell-tower backhaul service requires high standards of

performance to satisfy the demands of both voice and high-bandwidth data

services. Among these requirements are low transmission delay, low data

loss and high reliability/uptime. Optical network equipment that provides

backhaul service must be able to support these performance demands and

must also be environmentally hardened (to withstand extremes of heat,

moisture and cold) and that can be installed in outdoor cabinets. Another

critical requirement is exible cell tower voltage operation, including the

ability to operate at +24 V DC, used at many cell towers or standard telco

–48 V DC. Equipment not supporting these voltage options results in higher

capital and operational costs for cell-tower deployment.
