THE GROWING PROMISE OF WIRELESS.

The call for more content, greater speed and new communication protocols is

exploding across the U.S. and in many global markets, with strong demand for service

on the part of subscribers located beyond established areas of the public service

telephone network. As businesses become increasingly reliant on data communication

and internet-related services, wireless transmission is coming into its own as an

effective alternative for bandwidth delivery at high data rates.

Wireless communication has moved from a stop-gap solution to a fully functional

and highly competitive alternative for delivering broadband access. Mobile wireless

technology has the demonstrated potential to meet the needs of a full range of

communications services in small population-center markets, and for remote

locations and specialized facilities where conventional telco infrastructure cannot satisfy

the demand.

Services such as carrier-class telephony, high speed internet access, voice-over-internet,

direct broadcast satellite TV, real-time duplex video and video-on-demand represent

substantial revenue opportunities for telecommunication providers and network suppliers.

These services can now be effectively provided by means of a wireless infrastructure,

which also eliminates the high costs of establishing right-of-way, installing poles,

trenching cables and placing hard-wired facilities in areas of severe weather or difficult

terrain. It makes it possible to provide subscribers with the full range of broadband

services within a matter of hours rather than days or even weeks.

PUBLIC SWITCHED TELEPHONENETWORK (PSTN)

The worldwide switched voice network.

PHYSICAL-MEDIA LAYER

The cable or physical medium overwhich data flows. Includes electrical

signals as well as all connecting, splicing, switching, splitting and

termination components.

CELLULAR

A typical cellular wireless site servesmobile phones in a dedicated area,

and is implemented by a cell operatorthat receives backhaul service from

a telco or network operator.

WIRELESS POINT-TO-MULTIPOINT

BROADBAND/WIMAX

Signals are fed from a central office or other location to the

base station, and then by wireless point-to-multipoint to remote

customer equipment.

WIRELESS POINT-TO-POINT

A wireless hut installation is typicallyused in remote locations where theoperator does not have access to a fiber ring. Signals are transmitted to the hut by wireless point-to-point transmission from another location,

and passed to subscribers over conventional outside plant distribution, including both

POTS and data.

KEY TERMS

CONVERGENCE TO

INTERNET PROTOCOL.

Traditional Public Switched

Telephone Network (PSTN) is

limited in its ability to handle the

exploding demand for services, and

is vulnerable to traffic overload.

Because the packet-based nature

of Internet protocol is not subject

to this capacity limitation, it is fast

becoming the connectivity choice

for high-volume, mixed transmission

requirements and the common

unifying element in worldwide

communication growth.

MEDIA DATA

WIRELESSINTERNET

Historically, wireless and internet

applications have been on

fundamentally separate tracks.

However, approximately

seventy-five percent of today’s

cellular subscribers use the

Internet, and by 2005 an

estimated one billion wireless

subscribers are expected to

seek Internet access. While

the transition to packet-based

applications requires new

connectivity and switching

hardware, the nature of the

physical-media layer of the

OSI model remains unchanged.

THE PHYSICAL-MEDIA LAYER FOUNDATION.

The Open Systems Interconnection Model (OSI) definesseven layers that describe the functionality of a network,from physical connections to the user applications, andincludes all signal details and transfer protocols.

THE PHYSICAL-MEDIA LAYER. • The physical path which the information

will travel across• Each layer affects the overall service quality;

but none is more critical than the media layer• All communication processes are dependent

upon the media layer

THE MOBILE

SWITCHING CENTER.

This center serves as a

network node in a wireless

telecommunications network

and as a point of access to

the Public Switched Telephone

Network. Also sometimes known

as a Mobile Telephone Switching

Office or Mobile Switching Office,

it is similar to a central office

switch that bridges a mobile

telephone network with digital

and fiber distribution frames,

fiber-optic and copper cable

assemblies, vault closures and

cross-connect blocks and

electrical protection. 3M is

uniquely positioned to provide

packaged solutions for the

entire physical network.

BACKHAUL/OSP.

The backhaul network (outside

plant installation) provides the

signal path between the mobile

switching center and the wireless

base station. It comprises fiber

optic or copper cables and

splices, closures, cabinets

and cross-connect blocks.

Maintenance requires locating

and testing capabilities,

with underground markers

to rapidly pinpoint and expose

components without damage.
