The Telecommunications Industry Association (TIA) is accredited by the American National Standards Institute (ANSI) to develop voluntary, consensus-based industry standards for a wide variety of Information and Communication Technologies (ICT) products, and currently represents nearly 400 companies. TIA's Standards and Technology Department operates twelve engineering committees, which develop guidelines for private radio equipment, cellular towers, data terminals, satellites, telephone terminal equipment, accessibility, VoIP devices, structured cabling, data centers, mobile device communications, multimedia multicast, vehicular telematics, healthcare ICT, machine to machine communications, and smart utility networks.

Active participants include communications equipment manufacturers, service providers, government agencies, academic institutions, and end-users are engaged in TIA's standards setting process. To ensure that these standards become incorporated globally, TIA is also engaged in the International Telecommunication Union (ITU), the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC).

TIA merged in 2017 with the Quest Forum, home of the TL9000 quality standard for operators, which substantially increased the number of companies under the TIA umbrella. The boards of the two organizations were combined into a single board. The headquarters of the combined organization was the TIA location in Arlington, Virginia.
