Long-Term Evolution

/ˌɛl tiː iː/

noun — "high-speed 4G mobile connectivity."

LTE , short for Long-Term Evolution, is a wireless broadband technology that provides high-speed data and improved capacity for mobile networks. It is part of the 4G standard and represents a major evolution from 3G networks, offering higher peak data rates, lower latency, and more efficient spectrum use. LTE is widely deployed worldwide to deliver mobile Internet, VoIP, video streaming, and enterprise connectivity over cellular networks.

Asymmetric Digital Subscriber Line

/ˌeɪ diː ɛs ɛl/

noun — "high-speed Internet over ordinary phone lines."

ADSL (Asymmetric Digital Subscriber Line) is a type of DSL technology that provides broadband Internet access over existing copper telephone lines. The "asymmetric" designation means that download speeds are higher than upload speeds, reflecting typical consumer usage patterns where downloading content dominates uploading. ADSL enables simultaneous voice and data transmission by separating low-frequency voice signals from higher-frequency data signals.

Digital Subscriber Line Access Multiplexer

/ˈdiː ɛs ɛl æm/

noun — "the network junction that aggregates DSL lines."

DSLAM (Digital Subscriber Line Access Multiplexer) is a network device that collects multiple DSL connections from subscribers and aggregates them into a high-speed backbone link for transmission to an Internet service provider’s core network. It acts as a central hub that manages signal multiplexing, traffic routing, and line management, enabling efficient broadband delivery over existing copper telephone lines.
