TR-8.11 Antenna Systems
Definition of terms, methods of measurement, and equipment specifications for radiating devices and associated components in public and private Land Mobile radio systems. “Associated components” include all components that lie in the RF path between a radiating device and its associated transmitter or receiver or between two radiating devices. This scope excludes specific activities assigned…
TR-8.12 Two Slot TDMA
To establish the definition of terms, methods of measurement, and functional specifications for enabling implementation of an interoperable Two Slot TDMA Air Interface, excluding specific assigned activities within other TR-8 subcommittees.
TR-8.15 Common Air Interface
Establish standards defining the protocol necessary for digital-based equipment for land mobile services. The Common Air Interface is the radio communications interface shared by the portable, mobile, and base station equipment. The Common Air Interface allows these radios to send and receive digital information over a narrow band radio channel. Related Materials: “Conventional Procedures” Stakeholders…

To establish common terms, definitions, and methods of measurement to aid interested parties in evaluating adherence to Federal Communication Commission guidelines concerning Radio Frequency exposure.
TR-8.18 Wireless Systems Compatibility – Interference and Coverage
Definition of terms and methodology for the modeling, simulation, and empirical performance verification of land mobile radio systems.
TR-8.19 Wireline System Interfaces
Establish standards defining interoperability, interconnection and compatibility between Private Land Mobile Radio services and wireline systems. Wireline system interfaces may include, but are not limited to, console, fixed station, intersystem, telephone interconnect and network management.
TR-8.21 Land Mobile Radio (LMR) Intrinsic Safety(IS) Consideration
The scope of the TR-8.21 Land Mobile Radio (LMR) Intrinsic Safety (IS) Sub-Committee includes, but is not limited to, the development of technical proposals and papers on IS topics of interest to standards development organizations, product testing and certification organizations, relevant professional groups, and relevant government agencies.
TR-8.25 Compliance Assessment
The Compliance Assessment Subcommittee shall be responsible for the resolution of compliance assessment related questions.
The Encryption Working Group was established to develop the encryption standards for public-safety land mobile communication.
The Vocoder Working Group was created to develop and support Vocoder standards for Project 25 compatible land mobile radio equipment. It is the goal of these standards to sufficiently define the Vocoder and specify verification methods such that competing manufacturers may produce inter-operable equipment. These standards will include a technical description of the Project 25…
