The Telecommunications Industry Association (TIA) is the leading trade association representing the global information and communications technology (ICT) industry through standards development, policy initiatives, business opportunities, market intelligence and networking events. With support from hundreds of members, TIA enhances the business environment for companies involved in telecom, broadband, mobile wireless, information technology, networks, cable, satellite, unified communications, emergency communications and the greening of technology.
The Terrestrial and Non Terrestrial Mobile Multimedia Multicast TR-47 committee is responsible for the development and maintenance of voluntary downlink standards for terrestrial and non-terrestrial mobile multimedia multicast systems. These standards are intended to be employed by users and suppliers to promote compatible and interoperable systems to support multicast audio, video and data requirements for a wide range of commercial and public services.
The Mobile and Point-to-Point Communications Standards TR-45 committee develops performance, compatibility, interoperability and service standards for mobile and personal communications systems. These standards pertain to, but are not restricted to, service information, wireless terminal equipment, wireless base station equipment, wireless switching office equipment, ancillary apparatus, auxiliary applications, inter-network and intersystem operations, interfaces, and wireless packet data technologies.
The Performance and Accessibility for Communications Products TR-41 committee develops and maintains voluntary standards for the performance and accessibility of communications products. The products addressed by these standards include telephones with handsets, headsets, and speakerphones, communications gateways, and other products that are typically installed at the user’s premises. The products may connect to a communications network using digital and analog wireline or radio (e.g., Wi-Fi® or Bluetooth®) media. They may connect directly to the network or through another device (e.g. a USB headset connected through a computer). TR-41’s standards may include performance requirements for voice, video, and other features that are associated with communications services. They cover requirements for a product’s performance related to signal transmission, environmental impacts, interfacing to networks and other equipment, accessibility, and usability. TR-41 addresses issues pertaining to administrative aspects of regulatory product approval processes and develops criteria for preventing harm to the telephone network, which become mandatory when adopted by the Administrative Council for Terminal Attachments (ACTA). TR-41 is a point of contact for expert technical opinions, advice, and actions for standards development for government agencies that deal with communications including the FCC. It also provides input to other organizations that develop and publish product safety standards.
The Multi-Media Access, Protocols and Interfaces TR-30 engineering committee develops standards related to the functional, electrical and mechanical characteristics of interfaces between data circuit terminating equipment (DCE), data terminal equipment (DTE) and multiMedia gateways, the telephone and voice-over-Internet protocol (VoIP) networks, and other DCE and facsimile systems.
Mobile and Personal Private Radio Standards TR-8 engineering committee formulates and maintains standards for private radio communications systems and equipment for both voice and data applications. TR-8 addresses all technical matters for systems and services, including definitions, interoperability, compatibility and compliance requirements. The types of systems addressed by these standards include business and industrial dispatch applications, as well as public safety (such as police, ambulance and fire fighting) applications.
