The products, technologies, and technical areas within the scope of current and/or future standards developed and maintained by TR-41 include:

  • Performance requirements for
    • Voice, video, and other features that are associated with communications services.
    • Environmental impacts.
    • User related features that interface to networks and other equipment.
    • Accessibility and usability.
  • Covering products that connect to a communications network including:
    • Telephones with handsets, headsets, and speakerphones.
    • Communications gateways, conference systems, and other products that are typically installed at the user’s premises.
    • Wearable devices (e.g., watches, lapel microphones).
    • Using digital and analog wireline or “local radio” media (e.g., Wi-Fi® or Bluetooth®).
    • Directly or through another device (e.g. a USB headset connected through a computer).
    • For features that use wireless “air interfaces” (e.g., LTE, GSM, WCDMA).

    TR-41.3 Performance and Accessibility for Communication Devices

    Mission & Scope
    TIA Subcommittee TR-41.3 develops and maintains voluntary standards for communications devices including requirements and testing methods for evaluating the performance of a device's audio and electro-acoustics, network interfaces, features, accessibility and environmental robustness. Devices covered by these standards may include traditional communication devices with corded or radio-linked handsets, headsets, and hands-free (speakerphone) interfaces. In addition devices such as wearables, appliances, and multi-media, systems may be covered by these standards. Electro-acoustics requirements may include any audio frequency band from (e.g., Narrowband (300 to 3,400 Hz) to Fullband (20 to 20,000 Hz)) TR-41.3 will maintain liaison and may participate in joint standards development activities with other standards organizations in the U.S., Canada, and other countries.
