    1. The first version of technology that provides packet-data capabilities to wireless networks and has peak downlink speeds of 307 Kbps and uplink speeds of 144 Kbps. It was incorporated into 2.5G wireless standards.

    2. The first phase of CDMA technology that increases peak download speeds to 2.4 Mbps. It was incorporated in 3.5G wireless standards.

    3. The original standards for mobile phone networks and is based on analog technology. The networks were designed primarily to carry voice traffic.

    4. The second standards of mobile phone technology that included the conversion of voice to digital data for transmission over the air and then back to voice. 2G data services were based on circuit-switched data connections where each connection was dedicated to the user for the duration of each session. Circuit switched data was slow, typically providing 9.6-14.4 Kbps. 2G technologies included Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), and GSM (Global System for Mobile communications).

    5. While there are no official definitions for 2.5G, it refers to technology that is added to a 2G network to provide packet-data capabilities. 2.5G technologies include GPRS and EDGE for GSM and 1xRTT for CDMA. EDGE and 1xRTT are also sometimes referred to as 2.75G technologies as well.

    6. The third generation of mobile phone standards and technology. A key aim of 3G standards was to enable mobile broadband data speeds above 384kbps. 3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Advanced services include video and multimedia messaging, and broadband wireless data, all in a mobile environment. 3G technologies include Wideband-CDMA, (W-CDMA), cdma2000 and TD/SCDMA.

    7. Refers to evolutionary upgrades to 3G services that provide significantly enhanced broadband wireless data performance to enable multi-megabit data speeds. The key 3.5G technologies in North America are High-Speed Packet Access (HSPA) and CDMA EV-DO.

    8. A technology that offers increased voice, video and multimedia capabilities; a higher network capacity; improved spectral efficiency; and high-speed data rates over current 3G benchmarks.

    9. Denotes a very specific television display resolution of 4096 x 2160. Today’s 1920 x 1080 resolution full HD televisions present an image of around 2 megapixels, while the 4K generation of screens delivers an 8 megapixel image.

    10. See WiFi.

    11. See WiMAX.

  2. A

    1. The part of the carrier network that touches the customer’s premises in a wireline network or the connection to the cell site in a wireless network. The access network is also referred to as the local loop, or last mile.

    2. A digital local loop typically using copper facilities and providing greater bandwidth in one direction than the other. It is « asymmetric » because it provides much higher speeds downloading than uploading. This technology is used to transmit data at fast rates on existing copper phone lines.

    3. Charges to users of wireless networks based on a flat rate or on minutes of use for voice services, or kilobits or megabits for data services.

    4. A device that boosts the strength of an electronic or radio frequency signal.

    5. AMPS was the original analog cellular system deployed in North America. AMPS used FDMA transmission technology and narrowband FM modulation to create channels, dividing geographic areas into cells where each connection uses a dedicated frequency. AMPS is the cellular equivalent of POTS.

    6. The electrical transmission accomplished by adding signals of varying frequency or amplitude to carrier waves of a given frequency of altering electromagnetic current. Broadcast and phone transmission has conventionally used analog technology. In telecommunications, analog refers to a transmission standard that uses variable frequencies and amplitudes of electrical impulses to emulate the audio waveform of sound.

    7. This business performance measure expressed as a dollar rate per month includes all the revenue generated by account as opposed to user or device so that a customer who has many devices (each device would have a different ARPU) will have a higher ARPA than a customer with only one device. In other words, ARPA is the sum of the device ARPUs for a given customer.

    8. Average revenue per user, or subscriber, expressed as a dollar rate per month for a given measurement period. Predominantly used in the wireless and cable industries to describe the revenue generated per customer per month. ARPU is an indicator of a wireless or cable business’ operating performance.

    9. The wireless telecommunications spectrum band that is used for wireless voice, data, messaging services and multimedia.

  3. B

    1. Bandwidth can have two different meanings: (1) a band or block of radio frequencies measured in cycles per second, or Hertz; (2) an amount or unit of capacity in a telecommunications transmission network. In general terms, bandwidth is the available space to carry a signal: the greater the bandwidth, the greater the information-carrying capacity.

    2. A measurement of data transmission speed used for measuring the amount of data that is 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; Gbps (gigabits per second) is billions; Tbps (terabits per second) is trillions and Pbps (Petabits per second) is quadrillions.

    3. High-speed transmission. The term is commonly used to refer to communications services which allow transmission of voice, data, and video simultaneously at rates of 1.544Mbps and above.

    4. A broadcast service is one that is delivered to all customers at the same time.

    5. Video content that is broadcast simultaneously to all users. Broadcast video may include multiple frequencies supporting multiple ‘channels’ of content and end user customers who can browse the frequencies using a tuner to select specific content.

    6. A very general term referring to the provisioning of two or more telecom services together, typically in a retail package.

  4. C

    1. A device which allows a computer end-terminal to initiate and affect a communications link with a cable modem termination system (CMTS) via a coaxial cable (« cable television ») network, using Internet Protocol (IP) and interconnecting with the Internet so as to provide the customer with Internet access.

    2. Compound annual growth rate.

    3. The telecommunications network facilities that provide cable service in a given geographic area.

    4. The transmission of real time voice communications over a cable network.

    5. An independent organization dedicated to working with consumers and service providers to resolve complaints about telephone and Internet services. Its structure and mandate were approved by the CRTC.

    6. The term used to describe the disconnect rate of customers to a telecommunications service. Usually expressed as a percentage and calculated as the number of subscriber units disconnecting in a one month period divided by the average number of units on the network. It is a measure of customer turnover and is often at least partially reflective of service quality and competitive intensity.

    7. A telecommunications provider company that competes with other, already established carriers, generally the incumbent local exchange carrier (ILEC).

    8. A synonym for distributed computing, and means the ability to run a program or application on many connected computers at the same time.

    9. The federal regulator for radio and television broadcasters, and cable-TV and telecommunications companies in Canada.
