4G (fourth generation): Wireless technologies, including HSPA+, LTE, LTE advanced and LTE advanced pro, as defined by the International Telecommunications Union.
5G (fifth generation): The next generation of converged wireless technologies, expected to provide higher Internet speeds, improved coverage and lower latency, which is critical as the number of connected devices continues to increase rapidly. 5G technical standards remain in development.
AWS (advanced wireless services) spectrum: Spectrum in the 1.7 and 2.1 GHz frequency ranges that is utilized in North America for 4G services. It is commonly used in urban and suburban areas.
Fibre-optic network: Hair-thin glass fibres along which light pulses are transmitted. Optical fibre networks are used to transmit large amounts of data between locations at high upload and download speeds.
FTTx (fibre to the x): A collective term for any broadband network architecture using optical fibre to replace all or part of the existing copper local loops. FTTH denotes fibre to the home, FTTP denotes premises and FTTN denotes node or neighbourhood.
GPON (gigabit-capable passive optical network): A fibre-based transmission technology that can deliver data download speeds of up to 2.5 Gbps and upload speeds of up to 1.25 Gbps.
HSPA+ (high-speed packet access plus): A 4G technology capable of delivering manufacturer-rated wireless data download speeds of up to 21 Mbps (typical speeds of 4 to 6 Mbps expected). HSPA+ dual-cell technology can double those download speeds.
ILEC (incumbent local exchange carrier): An established telecommunications company providing local telephone service.
Internet of Things (IoT): A network of uniquely identifiable end points (or things) that interact without human intervention, most commonly over a wireless network. These systems collect, analyze and act on information in real time and can be deployed to enable the creation of smart connected businesses, homes, cars and cities.
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 allows a variety of IP devices and advanced applications to communicate over a single common network.
IP TV (Internet protocol television): A television service that uses a two-way digital broadcast signal sent through a network by way of a streamed broadband connection to a dedicated set-top box. The TELUS service is offered as Optik TV and Pik TV
LAA (licensed assisted access): An LTE feature that makes use of unlicensed spectrum in combination with licensed spectrum to deliver a performance boost for mobile device users.
LTE (long-term evolution): The leading 4G global wireless industry technology standard. LTE advanced and LTE advanced pro offer higher speeds and greater capacity, moving networks closer to 5G.
M2M (machine-to-machine): Technologies and networked devices that are able to exchange information and perform actions without any human assistance.
Non-ILEC (non-incumbent local exchange carrier): The telecommunications operations of TELUS outside its traditional ILEC operating territories, where TELUS competes with the incumbent telephone company (e.g. Ontario and most of Quebec).
Normal course issuer bid (NCIB): A program that enables a company to purchase its own shares, typically for cancellation, through exchanges or private purchases over a set period of time.
Over-the-top (OTT): Content, services and applications in a video format, for which the delivery occurs through a medium other than the established video delivery infrastructure.
Roaming: A service offered by wireless network operators that allows subscribers to use their mobile phones while in the service area of another operator.
Small cell: Low-powered radio access nodes that can operate in licensed and unlicensed spectrum within a small range to provide densification and capacity to a macro wireless network.
Spectrum: The range of electromagnetic radio frequencies used in the transmission of voice, data and video. The capacity of a wireless network is in part a function of the amount of spectrum licensed and utilized by the carrier.
VoIP (voice over Internet protocol): The transmission of voice signals over the Internet or IP network.
Wave 3 solutions: Next-generation wireless offerings that use Internet of Things technology to provide solutions to businesses and consumers.
Wi-Fi (wireless fidelity): Networking technology that allows any user with a Wi-Fi-enabled device to connect to a wireless access point or hotspot in high-traffic public locations.
xDSL: A fibre-to-the-node IP technology that allows existing telephone lines to carry voice, data and video.
