What is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways?

enable the transmission of data over public or private networks

a communications, data exchange, and resource-sharing system created by linking two or  more computers and establishing standards, or protocols, so that they can work together

is designed to connect a group of computers in close proximity to each other  such as in an office building, a school, or a home

a network spanning a facility

Metropolitan area network (MAN)

a large computer network usually spanning a city

spans a large geographic area, such as a state, province, or country – INTERNET!

uses TCP/IP technology to transmit voice calls over long-distance telephone lines

Valued-added network (VAN)

a private network, provided by a third party, for exchanging information through a high capacity connection

is the difference between the highest and the lowest frequencies that can be transmitted on a single medi­um, and it is a measure of the medium's capacity

efers to high-speed Internet connections transmitting data at speeds greater than 200 kilobytes per second (Kbps)

Virtual private network (VPN)

a way to use the public telecommunication infrastructure (e.g., Internet) to provide secure access to an organization’s network

Personal digital assistants (PDA)

are small, handheld computers capable of entirely digital communications transmission – early PDAs did not support data communications

combines the functions of a cellular phone and a PDA in a single device

a telecommunications industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection

commonly used to transmit network signals over great distances

a big microwave repeater in the sky; it contains one or more transponders that listen to a particular portion of the electromagnetic spectrum, amplifying incoming signals, and retransmitting them back to Earth

Geographic information system (GIS)

is designed to work with information that can be shown on a mapFinding what is nearby, routing information, information alerts, mapping densities, mapping quantities

Location-based services (LBS)

are wireless mobile content services which provide location-specific information to mobile users moving from location to location

Global Positioning System (GPS)

is a "constellation" of 24 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location

Wireless fidelity (wi-fi)

a means of linking computers using infrared or radio signals

is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access

can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). It can also connect to another WiMAX tower using a line-of-sight, microwave link. This connection to a second tower (often referred to as a backhaul), along with the ability of a single tower to cover up to 3,000 square miles, is what allows WiMAX to provide coverage to remote rural areas

Radio frequency identification (RFID)

use active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers

contains a microchip and an antenna, and typically work by transmitting a serial number via radio waves to an electronic reader, which confirms the identity of a person or object bearing the tag

• Social networking gets mobilized • Mobile TV • Cheaper and more versatile multi-function devices • Location-based services • Mobile advertising • Wireless providers move into home entertainment • Wireless security moves to the forefront • Enterprise mobility

Dougie Worldwide Interoperability for Microwave Access WiMax), is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. It is based on the IEEE 802.16 standard, which is also called WirelessMAN. WiBro (Wireless Broadband,) is a wireless broadband Internet technology being developed by the Korean telecoms industry. WiBro is the Korean service name for IEEE 802.16e (mobile WiMAX) international standard. WiBro adapts TDD for duplexing, OFDMA for multiple access and 8.75 MHz as a channel bandwidth. WiBro was devised to overcome the data rate limitation of mobile phones (for example CDMA 1x) and to add mobility to broadband Internet access (for example ADSL or Wireless LAN). 15 years ago Source:
