Digital Trunked Radio System

SAES-T-493 standard specifically focuses on the engineering and installation requirements of Digital Trunked Radio Systems. However, it does not cover the design requirements for process automation systems. For process automation systems design requirements, you may need to refer to other relevant standards or documents that specifically address those requirements.

Industrial Codes and Standards

The provided list includes various industrial codes and standards relevant to communication systems, frequency plans, and equipment specifications. Here is a brief description of each standard or organization:

1. Saudi Arabia Communication & Information Technology Commission (SC&ITC): This is the regulatory body responsible for the communication and information technology sector in Saudi Arabia.
2. National Frequency Plan for Saudi Arabia (NFP): It outlines the allocated frequency bands and their authorized uses within Saudi Arabia.
3. ETSI ETS 100-392 Series: The European Telecommunications Standards Institute (ETSI) series of standards related to Terrestrial Trunked Radio (TETRA) systems.
4. ETSI EN 300 392: Standard for TETRA systems, specifically addressing voice and data transmission (V+D).
5. ETSI EN 300 394: Standard for TETRA systems, focusing on conformance testing specifications.
6. ETSI EN 300 395: Standard for TETRA systems, specifying the speech codec for full-rate traffic channels.
7. ETSI EN 300 396: Standard for TETRA systems, defining the technical requirements for direct operation (DMO).
8. ETSI EN 302 109: Standard for TETRA systems, concerning security measures and synchronization mechanisms for end-to-end encryption.
9. ETSI EN 301 489-18: Electromagnetic compatibility (EMC) standard for TETRA equipment.
10. ETSI EN 301 040: Standard for TETRA systems, focusing on lawful interception (LI) interfaces for security purposes.
11. ETSI EN 300 827: EMC standard for TETRA equipment and ancillary devices.
12. ETSI EN 303 035: Harmonized European Standard for TETRA equipment, ensuring compliance with essential requirements under the Radio and Telecommunications Terminal Equipment (R&TTE) Directive.
13. ETSI EN 300 812: Standard for TETRA systems, specifically addressing security aspects and the Subscriber Identity Module to Mobile Equipment (SIM-ME) interface.
14. ETSI ES 201 962: Standard for TETRA systems, covering TETRA Advanced Packet Service (TAPS).
15. UL Standards:

• UL 452: Standard for antenna discharge units used in radio and television receiving appliances.
• UL 497C: Standard for protectors used in coaxial communications circuits.

1. National Fire Protection Association (NFPA) 70 – 2008: Also known as the National Electric Code (NEC), it provides guidelines and requirements for electrical installations.
2. International Electrotechnical Commission (IEC) IEC 60079 – XX: Series of standards related to explosive atmospheres and electrical equipment used in such environments.

These standards and codes help ensure compliance, safety, and compatibility in the design, installation, and operation of communication systems and equipment.

Design of Digital Trunked Radio System

6.1 Spectrum Regulation and Approval

6.1.1 Digital Trunked radio equipment used in the project must conform and comply with the spectrum regulations set by the Saudi Arabia Communication & Information Technology Commission (SC&ITC) and the National Frequency Plan (NFP). Any spectrum allocation request and approval must be obtained from SC&ITC. It is important to note that obtaining spectrum approval from SC&ITC should be done through the IT Government Coordination Group, CE&TSD.

6.1.2 All Digital Trunked radio equipment used in the project must adhere to the importation procedures for radio telecommunication equipment into the Kingdom of Saudi Arabia. For the specific procedures related to radio equipment importation, reference should be made to the following requirement documents:

• MI-321.015: Materials Requiring Saudi Arab Government Import Permits, Letters of Authorization, and/or Clearance Permits
• MI-321.021: Import Permits for Communications Equipment
• GI-1603.000: Importation of Communications Equipment

6.1.3 Any new frequency assignments allocated to Saudi Aramco for the project must be surveyed and scanned by the project team to ensure that interference-free channels are available prior to utilization.

6.1.4 All detailed design packages related to the TETRA project must undergo a review process by CE&TSD (IT Government Coordination Group).

6.2 Portable Devices Use

All portable electrical/electronic devices used in the project must adhere to the minimum requirements specified in GI-0006.008. These requirements include restrictions, labeling, and proper use guidelines for portable devices.
