ADSL

ADSL (Asymmetric Digital Subscriber Line or DSL for short) is a high-speed Internet access service that utilizes existing copper telephone lines to send and receive data at speeds that far exceed conventional dial-up modems.

Analog Telephone Adaptor (ATA)

An analog telephone adaptor (ATA) is a device used to connect a standard telephone to a computer or local area network so that the user can make calls over the Internet.

Backhaul

Wireless backhaul is the use of wireless communications systems to get data from an end user to a node in a major network such as the Internet.

Bandwidth Access Management

Bandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link, which would result in network congestion and poor performance of the network.

Bridge device

A bridge device bridges the traffic from one network by simply rebroadcasting it to adjacent network segments.

Broadband

Broadband refers to telecommunication in which a wide band of frequencies is available to transmit information. Since wide band of frequencies is available, it allows more information to be transmitted in a given amount of time.

CCTV

Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. CCTV is used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores.

Connectivity

Connectivity is the ability to connect systems or application programs which may need to communicate with each other to complete transactions or to effectively balance resources at an installation.

CPE (Customer Premises Equipment)

Customer premises equipment (CPE) is service provider equipment that is located on the customer's premises (physical location) rather than on the provider's premises or in between.

Dial Up

Dialup internet service is a service that allows connectivity to the internet through a standard telephone line.

Digital subscriber line (DSL)

Digital subscriber line (DSL) is a family of technologies that provides digital data transmission over the wires of a local telephone network. DSL service is delivered simultaneously with wired telephone service on the same telephone line.

Ethernet

Ethernet is the most widely-installed local area network (LAN) technology. An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires and is also used in wireless LANs.

Fixed Wireless Broadband

Fixed wireless broadband is a type of high-speed Internet access where connections to service providers use a combination of radio frequency signals and cables.

Front to back ratio

In telecommunication, the term front-to-back ratio (also known as front-to-rear ratio) can mean:
1. The ratio of power gain between the front and rear of a directional antenna.
2. Ratio of signal strength transmitted in a forward direction to that transmitted in a backward direction.

IEEE802.11a/b/g/n standards

IEEE refers to Institute of Electrical and Electronics Engineers. IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands.

Indoor/Outdoor Access Point

Wireless access points (APs or WAPs) are specially configured nodes on wireless local area networks (WLANs). Access points act as a central transmitter and receiver of WLAN radio signals. Access points support Wi-Fi wireless communication standards.

Internet

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP). It carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW).

Kbps, MBps, GBps

The data rate of a computer network connection is normally measured in units of bits per second (bps).
◙ One megabit per second (Mbps) equals 1000 Kbps or one million bps
◙ One gigabit per second (Gbps) equals 1000 Mbps or one million Kbps or one billion bps

Data rates for non-network equipment are sometimes shown in bytes per second (Bps) rather than bits per second. In those cases,
◙ One KBps equals one kilobyte per second
◙ One MBps equals one megabyte per second, and
◙ One GBps equals one gigabyte per second
◙ Finally, one kilobyte per second equals 8 kilobits per second.

LAN

A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home. A LAN is useful for sharing resources like files, printers, games or other applications.

Last mile application

The "last mile" or "last kilometer" is the final leg of delivering connectivity from a communications provider to a customer.

Leased Lines

A leased line connects two locations for private voice and/or data telecommunication service. Leased lines can span short or long distances.

Network

A computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information.

Network processor

Network processors are typically software programmable devices commonly used in many different types of network equipment and products.

Orthogonal Frequency-Division Multiplexing (OFDM) technology

Orthogonal frequency-division multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at different frequencies. This technology enables connectivity at lower cost.

Polarization

Antenna polarization is a very important consideration when choosing and installing an antenna. Most communications systems use vertical,
horizontal or circular polarization.

◙ An antenna is said to be vertically polarized (linear) when its electric field is perpendicular to the Earth's surface.
◙ Horizontally polarized (linear) antennas have their electric field parallel to the Earth's surface.
◙ A circular polarized wave radiates energy in both the horizontal and vertical planes and all planes in between.

Point to Multipoint connectivity

Point-to-point interfaces are used in serial communication. Simply: 1 source port to 1 destination port Point-to-multipoint connects one station to several other stations. Simply: 1 source port to multiple destination ports

RFID

Radio-frequency identification (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object.

Signal strength

In telecommunications, particularly in radio, signal strength refers to the magnitude of the electric field at a reference point that is a significant distance from the transmitting antenna.

Stub loaded helix (SLH) Antenna

The Stub Loaded Helix is a compact helix antenna with performance characteristics similar to a conventional helix but only one-quarter the size.

Supersonic speed

Supersonic speed is a rate of travel of an object that exceeds the speed of sound. For objects traveling in dry air of a temperature of 20 °C (68 °F) this speed is approximately 343 m/s, 1,125 ft/s, 768 mph or 1,235 km/h.
