• Air band VHF/UHF radios, base stations, and associated ground communication equipment.
• Analog and digital conventional VHF/UHF radios and repeaters.
• Radio gateways and interfaces for interconnecting radio systems with:
– IP networks and VoIP/dispatch solutions
– Telephone systems (PABX, SIP)
– Recording and logging systems.
• Power systems associated with radio sites, including DC plants, UPS, and backup power.
III. Technical Knowledge
Working knowledge of:
• TETRA system architecture and operation (TBS, MSC/SW, control channels, talk groups, encryption concepts).
• Air band radio fundamentals (frequency allocation, AM modulation, channel spacing, operational procedures and standards).
• Conventional radio technologies (FM, digital modes), repeaters, duplexers, and combiners.
• Radio frequency (RF) basics: frequency, power, dB/dBm, coverage, interference, antenna patterns, and propagation.
• Reading and interpreting system diagrams, frequency plans, and coverage maps.
• Use of test equipment: service monitor, spectrum analyzer, field strength meter, SWR/return loss meter, multimeter.
• IP fundamentals for radio interconnection (basic routing, VLANs, QoS concepts for voice over IP).
• Electrical and power concepts related to radio equipment, including grounding and surge protection.
IV. Duties
The technician will perform, but not be limited to, the following duties:
• Installation, configuration, and commissioning of:
– TETRA base stations, handhelds, repeaters, and dispatch consoles
– Air band and conventional radio base stations and repeaters
– Antennas, feeders, duplexers, and related RF components
• Interconnection of radio systems with other networks and services, including:
– Radio-over-IP (RoIP) gateways and dispatch/console systems
– Integration with PABX/SIP telephony and recording systems
– Cross-banding and interoperability solutions between disparate radio systems
• Antenna system work:
– Mounting and aligning antennas to specification
– Coaxial cable routing, termination, and testing
– Grounding, bonding, and lightning/surge protection
• Performing and documenting:
– Coverage and RSSI/BER measurements
– Audio quality and functionality checks (call setup, group calls, emergency calls)
– Acceptance and commissioning tests, with clear reporting
• Preventive and corrective maintenance on all radio and associated infrastructure to ensure continuity of operations, including firmware updates and configuration backups.
• Assisting senior engineers or the Chief Operations Officer in frequency planning, interference investigation, and optimization of radio coverage and capacity.
• Participation in a standby/on-call roster to support after-hours and emergency interventions as required.
V. Networking Skills
Enhanced requirements:
• Ability to integrate TETRA and other radio systems with IP networks, including basic switch configuration (VLANs, trunks, QoS for voice traffic).
• Familiarity with SIP/VoIP concepts for radio-telephony interconnection.
• Basic knowledge of VPNs, authentication, and cybersecurity best practices relevant to remote radio site access and IP-connected radio equipment.
• Ability to use remote management tools and NMS platforms for monitoring radio and network equipment.
VI. Experience & Certification
• Minimum 5 years’ hands-on experience with professional radio communication systems, including TETRA and/or air band equipment.
• Relevant Technical College Certificates or equivalent professional qualifications in telecommunications, electronics, or radio engineering.
• Manufacturer-specific training/certification on TETRA or professional radio systems is required.
• Rigging Certificate is highly Desirable
• Experience in mission-critical or public safety communications environments is highly desirable.
• Valid national driver’s license for light motor vehicles; ability to operate 4x4 manual transmission vehicles (where required and to be verified in the mission area).
VII. Language
• Fluency in English, both written and oral, is required.
• Fluency or working knowledge of French or Spanish is highly desirable as an additional language.
