Signal Transmission
We sometimes
say that misunderstandings are due to people being out of
sync or not on the same wavelength. When it comes to our
communications devices, these expressions are literally
true. Precision measurement of time and frequency are essential
to communications. So are a host of other measurement tools
and standards. Read on to see how NIST provides communications
measurements and standards.
Time
and Frequencymaintains one of the most accurate
atomic clocks in the world; provides time and frequency
signals necessary for radio, television, phone, and Internet
communication, as well as navigation and space exploration.
Antenna
Metrologyhelps industry determine performance of
antennas and related components for satellites, radar, and
communications systems.
Optoelectronics
Manufacturing Group helps
keep phone, email, and cable television signals from
degrading with NIST-developed
measurement tools that help industry accurately measure
optical fiber diameters to within a millionth of a meter.
Optical
Components Groupcharacterizes the properties of
optical fiber and optical communication systems components;
develops wavelength standards for optical communications.
Standard
Reference Materials for optical fibershere's a
list of optical fiber and wavelength calibration standards
for telecommunications.
NIST's
Manufacturing Extension Partnership, a nationwide network
of assistance centers for small manufacturers in all 50
states and Puerto Rico, offers expert advice on productivity
and modernization. Since 1988, MEP has assisted more than
100,000 firms, including communications companies.
CommScope,
Inc., of Scottsboro, Ala., a maker of fiber optic and
coaxial
cable, sought advice from its local Manufacturing
Extension Partnership center, the Alabama
Technology Network, for its spool winding operation.
With ATN assistance, CommScope increased productivity.

Wireless
We ask
a lot from the tiny, intricate components that make up cellular
telephones, pagers, and other miniature communications devices.
In order to deliver clear communications, key parts have
to perform consistently in a wide range of temperatures.

Security
In the
electronic age, words like hacker and virus have taken on
new meaning. And efforts to secure electronic information
are becoming increasingly important. NIST helps secure electronic
data by identifying vulnerabilities and cost-effective security
measures. The links below describe what we're doing to secure
electronic information.

Other Resources
NIST
outreach programs work directly with business and industry
to boost U.S. economic competitiveness. Many communications
companies have benefitted by taking advantage of these programs.
NIST's
Advanced Technology Program
spurs innovation in U.S. industry by co-funding high-risk,
high-payoff projects with private industry.
Smaller
manufacturers face many challenges in our technology-driven
environment. To help meet these challenges, NIST started
the Manufacturing Extension
Partnership program in 1988. This nationwide network
of centers, now in all 50 states, has assisted more than
10,000 U.S. firms, including communications firms.
The
Baldrige National
Quality Program recognizes performance excellence and
quality achievement by U.S. manufacturers, service companies,
educational organizations, and health-care providers. Communications
firms have been competing for the Baldrige Award since it
was established in 1988. In 1995, Corning
Telecommunications Products Division won the Baldrige
Award. In 1994, AT&T
Consumer Communications Services and GTE
Directories Corporation were selected as winners. In
1992, two divisions of AT&T won: AT&T
Network Systems Group and AT&T
Universal Card Services. Motorola
Inc. was one of the very first Baldrige Award winners
in 1998.
Organizations
that apply for the Baldrige Award must address seven key
criteria: leadership, strategic planning, customer and market
focus, information and analysis, human resource focus, process
management, and results. Each applicant receives a feedback
report citing strengths and opportunities for improvement.
Award recipients and applicants alike say the application
process can yield significant process improvements and is
good for the bottom line. In fact, a fictitious 'Baldrige
Index' made up of winning company stock has consistently
outperformed the Standard & Poor's 500 Index. And thousands
of other companies have used the Criteria
for Performance Excellence to assess and improve their
overall performance.
