Telecom Practices, Safety and Regulatory Framework in India
This domain tests field and laboratory safety plus Indian telecom regulation: licensing, spectrum, standards, EMF limits and laser safety. Questions often present a workplace scenario and ask for the correct safe practice.
Core rules
- The Indian Telegraph Act 1885 provides the legal basis for telecom; the TRAI Act 1997 created the regulator, TRAI, with DoT as the administrative/licensing authority.
- Wireless equipment and spectrum use require WPC (Wireless Planning and Coordination) approval; unauthorised transmission is an offence.
- Telecom equipment must meet TEC/MTCTE certification and relevant BIS standards.
- Optical fibre safety: never look into a fibre or connector; use an optical power meter. Lasers are classified under IEC 60825.
- Electrical safety: lockout/tagout, protective earthing, RCD/ELCB, insulated tools, and discharge before touching capacitors.
- Tower and battery work requires fall arrest, two-person rule, acid handling precautions and correct PPE.
- Call-before-you-dig and route surveys prevent damage to underground OFC.
Worked example
A technician must test a suspected broken 1310 nm patch cord. Correct sequence: switch off the laser source, use a fibre scope or visual fault locator with eye protection, confirm with an optical power meter, and never stare into the connector. Using a naked eye or an uncertified camera is unsafe because invisible infrared can damage the retina.
Traps that cost marks
- Confusing TRAI (regulator) with DoT (policy/licensing) and WPC (spectrum).
- Assuming low-power lasers are always eye-safe.
- Skipping earthing or using a multimeter on a live high-energy circuit.
- Ignoring EMF exposure norms near antennas.
- Failing to record an incident or near-miss.
Exam approach
Read the scenario, identify the hazard, then choose the control: eliminate, substitute, engineer, administrate, or PPE. Name the authority or standard when the question asks who regulates.
