currently being developed by Symbian, a consortium that includes
Psion, Ericsson, Panasonic, Motorola, and Nokia.
ESN(electronic serial number):
Unique identification number embedded in a wireless phone by the
manufacturer to prevent fraud. ESN differs from the mobile identification
number, which is the wireless carrier's identifier for a phone
in the network.
Fixed wireless data:
Wireless services to a fixed location through larger antennas
than are seen in mobile or portable setups. The fastest data throughputs--up
to T-1 speed-are available over fixed wireless networks.
FULL USER MOBILITY:
Wireless classification under which users can access data while
on the move, such as in a car.
A ground-based link to a mobile satellite service network.
GEOS(geo-stationary Earth orbit systems):
Communications system with satellites in geosynchronous orbits
22,300 miles above the Earth.
GMPCS(global mobile personal communications services):
Future mobile satellite systems that will provide global wireless
GPRS(general packet radio service):
An enhancement of the GSM core network that introduces packet
data transmission. It makes very efficient use of available radio
spectrum, and users get more access bandwidth than over a standard
GPS(global positioning system):
Series of 24 geosynchronous satellites that continually transmit
their position. GPS is used in personal tracking, navigation,
and automatic vehicle location technologies.
GSM (global system for mobile communication):
Digital cellular or PCS standard used throughout the world and
the primary standard in Europe and Southeast Asia.
HDML(handheld device markup language):
Derived from hypertext markup language, this programming language
allows Internet access from wireless devices such as handheld
personal computers and smart phones.
iDEN(integrated digital enhanced network):
Motorola enhanced mobile radio network technology that integrates
two-way radio, telephone, text messaging and data transmission
into a single network.
Term that refers to the new third generation global standard for
mobile telecommunications. Coined by the International Telecommunication
LEC(local exchange carrier):
Authorized carrier that has been commissioned to provide local
voice-level telecommunications services within a predetermined
LEO(low Earth orbit):
Mobile communications satellite between 700 and 2,000 kilometers
above the Earth.
LMDS(local multipoint distribution service):
Broadband radio service that enables two-way transmission of voice,
high-speed data, and video (wireless cable TV).
LNP(local number portability):
Subscribers' ability to switch local or wireless carriers and
still retain the same phone number, as is possible now with long-distance
carriers. Wireless carriers will not be required to offer LNP
until March 2000.
Modified Web browser that allows users to get Internet data on
a handheld wireless device - where getting good data, not good
graphics, counts the most.
Next generation of paging networks, enabling two-way acknowledgment
and "wireless answering machine" paging.
NIMBY (not in my back yard):
The sentiment of citizens opposing the nearby placement of undesirable
facilities such as antenna towers or waste dumps.
PAN (personal area network):
Experimental IBM technology that allows information devices to
discreetly communicate and synchronize with one another when in
close proximity using the human body as an antenna.
PCS (personal communication system):
Federal Communications Commission classification for digital wireless
communication systems based on the same principles of cellular
systems, but usually operating in a different frequency range
and with smaller cell sizes than cellular systems.
Portable wireless data:
Classification of networks that access the Internet by using a
laptop or palmtop computer and a small wireless modem.
SMS (short message service):
Electronic messages on a wireless network, such as those used
in two-way paging.
SS7 (Signaling System 7):
International high-speed signaling backbone for the public-switched
TDMA (time division multiple access):
Digital air interface technology used in cellular, PCS, and EMSR
TM-UWB(time-modulated ultra-wide band):
New wireless technology that greatly broadens bandwidth. Developed
by Time Domain, TM-UWB uses short, coded pulses transmitting over
a wide range of frequencies, making it useful for a wide range
of applications from networking to through-the-wall radar and
WAP (wireless application protocol):
Open, global specification that empowers mobile users with wireless
devices to easily access and interact with Web information and
A consortium that developed the WAP standard. Includes Phone.com,
Ericsson, Motorola, and Nokia.
WDF (Wireless Data Forum):
Industry group dedicated to promoting wireless data.
WIN (wireless intelligent network):
Wireless switched network that allows carriers to provide enhanced
and customized services for mobile phones.
Wireless LAN(local area network):
LAN that uses wireless transmissions such as radio or infrared-instead
of phone lines or fiber-optic-to connect data devices.
WML (wireless markup language):
The programming language designed by the WAP Forum for formatting
Web content to be viewed on handheld devices.
XML (extensible markup language):
An uberprogramming-language that might someday replace both HTML
and WML. Designed to be viewed on any kind of device.
