The Engineering Subcommittee is responsible for the development and maintenance of downlink standards for a subclass of terrestrial mobile multimedia multicast (TM3) systems. That subclass is characterized by the combining of the following features, among others:

• Purpose-built
• High spectral efficiency
• Multiple, simultaneous services
• Layered modulation.
• Layered service support
• Advanced coding
• Customized transport methods, not limited to Internet Protocol encapsulation
• Statistical multiplexing of variable-rate services
• High-quality Audio, video & data
• Content protection
• Multiple coverage areas (wide and local) within a single radio frequency (RF) channel
• Support different Quality of Service (QoS) for different services within a single RF channel
• Support different Quality of Service for different components within a single service
• Fast switching time between services
• Minimize receiver power consumption without sacrificing the time-diversity performance or the speed of service switching, regardless of the service rate
• Deterministic frame structure based on a time synchronizing signal such as Global Positioning System (GPS)

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 Engineering Subcommittee, through its parent, works with other national and international standards development organizations in promoting standards harmonization.

Work items are encouraged that are not duplicative of wireless data services architecture, interface and protocol development, such as done in Third Generation Partnership Project (3GPP), 3GPP2 and the Open Mobile Alliance (OMA), among others.

The Engineering Subcommittee's focus is on standards for radio interfaces, testing methodologies, performance and reliability standards, and equipment design guides as they relate to a subclass of terrestrial mobile multimedia multicast technologies described above

TR-50 Smart Device Communications

Engineering Committee TR-50 Smart Device Communications is responsible for the development and maintenance of access agnostic interface standards for the monitoring and bi-directional communication of events and information between smart devices and other devices, applications or networks. These standards development efforts pertain to but are not limited to the functional areas as noted:

• Requirements
• System Architecture
• Cross-industry communication
• Leverage existing (and future) physical infrastructure
• Information models (state diagrams)
• Security (e.g., data content, mutual authentication)
• End to End Performance and scalability of equipment and networks
• Network Management/Operations
• Device Management (incl. discovery and identity)
• Protocols
• Minimum Performance, Conformance and interoperability Testing

TR-50 will develop a Smart Device Communications framework that can operate over different underlying transport networks (wireless, wired, etc.) and can be adapted to a given transport network by means of an adaptation/convergence layer. The TR-50 framework will make its functionality available to applications through a well-defined Application Programming Interface (API) that is agnostic to the vertical application domain (eHealth, Smart Grid, Industrial Automation, etc.)

TR-50 works with other TIA Engineering Committees and non-TIA standards forums (international or national standards) to ensure end-to-end functionality and interoperability and to avoid overlap or duplication of work and to foster collaboration and coordination among organizations addressing various components of Smart Device Communication Systems.

Subcommittee TR-50.1 is assigned the authority of a Formulating Group (as defined in the TIA Engineering Manual), which includes the authority to develop and maintain publications (e.g. TIA Standards, American National Standards, TIA Service Bulletins). Such publications pertain to the access agnostic (e.g. PHY and MAC agnostic) monitoring and bi-directional communication of events and information between smart devices and other devices, applications or networks. The scope of work within Subcommittee TR-50.1 includes the following:

• The development and maintenance of publications pertaining to requirements. Such requirements shall be agnostic to the application (e.g. eHealth, Smart Grid, Industrial Automation, etc...), but shall reflect the requirements of the applications of interest. Examples of such publications include Use Cases and Stage-1 Descriptions.
• The development and maintenance of publications pertaining to system architecture. Such system architecture shall be agnostic to the application, but shall reflect the requirements of the applications of interest, including their information models. Such publications include, for example, description of the functional elements, definitions of relationships between functional elements, definitions of relationships between functional elements and elements external to the system, data flow diagrams, control flow diagrams, and definition of the application program program interface, State Diagrams and Stage-2 Descriptions.
• The development and maintenance of publications pertaining to data models. Such requirements shall be agnostic to the application, but shall reflect the requirements of the applications of interest. Examples of such publications include Stage-3 Descriptions, XML schema.

In its work, Subcommittee TR-50.1 shall take account of the following:

• Security (e.g., data content, authentication, signaling)
• End to End Performance and scalability of equipment and networks
• Device Management (incl. discovery and identity)
