1X: Technology standard for 3G (third generation) high-speed wireless Internet service at speeds of up to 153 Kbps. 1X was the first step in the CDMA2000 evolution. 1X provides enhanced voice network capacity as well as high-speed packet data mobile wireless Internet access.

3G (third generation): Describes wireless technology that offers highspeed packet data mobile wireless Internet access and multimedia communications at minimum transmission rates of 144 Kbps in mobile (outdoor) and two Mbps in fixed (indoor) environments. Analog cellular is the first generation of wireless and digital is the second.

4G (fourth generation): Describes the next generation of future wireless technology, which is still in the developmental stages. Long-term evolution (LTE) has emerged as the leading technology for adoption as 4G.

A

ADSL (asymmetric digital subscriber line): A technology that allows existing copper telephone lines to carry voice, data and video images at high speeds. It is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information upstream from the user.

ADSL2+: Increases the downstream data rate of ADSL to as much as 24 Mbps. These rates can be increased further by bonding multiple lines together to get data rates of up to 48 Mbps.

AWS (advanced wireless services) spectrum: AWS spectrum in the 2 GHz range, which is expected to be utilized in North America for 4G services.

gradient splitter

B

bandwidth: The difference between the top and bottom limiting frequencies of a continuous frequency band, or indicator of the information-carrying capacity of a channel. A greater bandwidth provides a greater information-carrying capacity.

bits per second (bps): A measurement of data transmission speed for the amount of data transferred in a second between two telecommunications points or within network devices. Kbps (kilobits per second) is thousands of bits per second; Mbps (megabits per second) is millions; and Gbps (gigabits per second) is billions.

gradient splitter

C

CDMA (code division multiple access): A wireless technology that spreads a signal over a frequency band that is larger than the signal to enable the use of a common band by many users, and to achieve signal security and privacy. CDMA2000 refers to the family of third generation wireless standards that use CDMA.

CLEC (competitive local exchange carrier): A category of telecommunications carriers, identified for regulatory purposes, that provide local exchange service in competition with an ILEC, using both the CLEC’s own switching and network or the CLEC’s switching facilities and a combination of either the CLEC’s network facilities or an ILEC’s unbundled network facilities.

CRTC (Canadian Radio-television and Telecommunications Commission): The federal regulator for radio and television broadcasters, and cable-TV and telecommunications companies in Canada.

gradient splitter

D

digital: A transmission method employing a sequence of discrete, distinct pulses that represent the binary digits 0 and 1 to indicate specific information, in contrast to the continuous signal of analog. Digital networks provide improved clarity, capacity, features and privacy compared to analog systems.

gradient splitter

E

EVDO (evolution data optimized): Part of the CDMA family of standards, EVDO is wireless radio broadband protocol that delivers data download rates of up to 2.4 Mbps. It is suitable for high bandwidth download applications such as enterprise VPN computing, music transfers and video streaming. EVDO Rev A (DOrA), the next generation of EVDO, adds data download rates of up to 3.1 Mbps, upload rates of up to 1.8 Mbps and higher system capacity, as well as improved quality of service support for data packet applications.

gradient splitter

F

fibre network: Transmits information by light pulses along hair-thin glass fibres, making it useful for transmitting large amounts of data between computers or many simultaneous telephone conversations.

forbearance: PPolicies refraining from the regulation of telecom services, allowing for greater reliance on competition and market forces.

gradient splitter

G

GPON (gigabit-capable passive optical network): A fibre-based transmission technology that delivers data download rates of up to 2.5 Gbps and upload rates of up to 1.25 Gbps.

GPS (global positioning system): A radio navigation system that allows users to determine and communicate their exact location, from anywhere in the world.

GSM (global system for mobile communication): A digital PCS mobile phone standard used in many parts of the world.

gradient splitter

H

hosting: TThe management of data, which incorporates the business of housing, serving and maintaining files for one or more websites.

hotspot: A Wi-Fi wireless access point in a public place.

HSPA (high-speed packet access): A 3.5 or higher generation GSM technology capable of delivering wireless data download speeds of up to 30 Mbps.

gradient splitter

I

iDEN (integrated digital enhanced network): A network technology developed by Motorola to utilize 800 MHz channels for digital service. The digital signals offer greatly enhanced spectrum efficiency and system capacity. TELUS uses this technology for its Mike service, which also includes PTT service.

ILEC (incumbent local exchange carrier): An established telecommunications company providing local telephone service.

IP (Internet protocol): A packet-based protocol for delivering data across networks.

IP-based network : A network designed using IP and QoS (quality of service) technology to reliably and efficiently support all types of customer traffic including voice, data and video. An IP-based network enables a variety of IP devices and advanced applications to communicate over a single common network.

IP TV (Internet protocol television): Television service that uses a two-way digital broadcast signal sent through a switched telephone or other network by way of broadband connection. The TELUS service is trademarked as TELUS TV.
