Term Definition
Files can be copied from or to a remote server, and also from one
remote server to another.
transponder A wireless communications, monitoring, or control device that picks up
and automatically responds to an incoming signal. The term is a
contraction of the words transmitter and responder. Transponders can
be either passive or active.
ultra high frequency (UHF) International Telecommunication Union (ITU) band 9, 300-3000 MHz,
1m - 100 mm frequency wavelength.
ultra wideband (UVB) Is a wireless technology for transmitting large amounts of digital data
over a wide spectrum of frequency bands with very low power for a
short distance. Ultra wideband broadcasts very precisely timed digital
pulses on a carrier signal across a very wide spectrum (number of
frequency channels) at the same time. UWB can carry a huge amount of
data over a distance up to 230 feet at very low power (less than 0.5
milliwatts), and has the ability to carry signals through doors and other
obstacles that tend to reflect signals at more limited bandwidths and a
higher power.
virtual private network (VPN) A network that uses a public telecommunication infrastructure, such as
the Internet, to provide remote offices or individual users with secure
access to their organization's network. A VPN ensures privacy through
security procedures and tunneling protocols such as the Layer Two
Tunneling Protocol ( L2TP ). Data is encrypted at the sending end and
decrypted at the receiving end.
voice over WLAN (VoWLAN) A method of routing telephone calls for mobile users over the Internet
using the technology specified in IEEE 802.11b. Routing mobile calls
over the Internet makes them free, or at least much less expensive than
they would be otherwise.
wideband code-division
multiple access (W-CDMA)
Officially known as IMT-2000 direct spread; ITU standard derived from
Code-Division Multiple Access (CDMA). W-CDMA is a third-generation
(3G) mobile wireless technology that promises much higher data
speeds to mobile and portable wireless devices than commonly offered
in today's market.
Wi-Fi A term for certain types of WLANs. Wi-Fi can apply to products that use
any 802.11 standard. Wi-Fi has gained acceptance in many businesses,
agencies, schools, and homes as an alternative to a wired LAN. Many
airports, hotels, and fast-food facilities offer public access to Wi-Fi
networks.
WiMAX A wireless industry coalition whose members organized to advance
IEEE 802.16 standards for broadband wireless access (BWA) networks.
WiMAX 802.16 technology is expected to enable multimedia
applications with wireless connection and, with a range of up to 30
miles, enable networks to have a wireless last mile solution. According
to the WiMAX forum, the group's aim is to promote and certify
compatibility and interoperability of devices based on the 802.16
specification, and to develop such devices for the marketplace.
