CAD CAD Antenna Designer Regulatory and Standards Compliance 1 — Questions and Answers
Question 1: Which U.S. federal agency is responsible for regulating antenna emissions and frequency allocations for commercial wireless systems?
- FCC (Correct answer)
- FAA
- OSHA
- EPA
Correct answer: FCC
The Federal Communications Commission (FCC) governs antenna emissions, frequency allocations, and licensing for commercial wireless systems in the U.S.
Question 2: What does EIRP stand for in antenna regulatory contexts?
- Equivalent Isotropically Radiated Power (Correct answer)
- Effective Internal Radio Power
- Emitted Infrared Radiation Parameter
- Electronic Interference Radiated Potential
Correct answer: Equivalent Isotropically Radiated Power
EIRP stands for Equivalent Isotropically Radiated Power, the total power radiated in the direction of maximum gain relative to an isotropic antenna.
Question 3: Which IEEE standard specifically addresses antenna definitions, terminology, and test methods?
- IEEE Std 149 (Correct answer)
- IEEE Std 802.11
- IEEE Std 1613
- IEEE Std 519
Correct answer: IEEE Std 149
IEEE Std 149 (Standard Test Procedures for Antennas) defines recommended methods for measuring antenna parameters and establishes standard terminology.
Question 4: FCC Part 15 regulations limit unintentional radiator emissions primarily to prevent what?
- Interference with licensed radio services (Correct answer)
- Overvoltage on power lines
- RF burns to users
- Satellite signal attenuation
Correct answer: Interference with licensed radio services
FCC Part 15 sets emission limits for unintentional radiators to prevent harmful interference with licensed radio services.
Question 5: What is the maximum permissible exposure (MPE) standard used in the U.S. to evaluate RF radiation safety near antennas?
- FCC OET Bulletin 65 (Correct answer)
- MIL-STD-461
- ANSI C63.4
- IEC 62232
Correct answer: FCC OET Bulletin 65
FCC OET Bulletin 65 provides the standard guidelines and calculation methods for evaluating RF exposure compliance near antenna installations.
Question 6: Which ITU radio regulation document allocates the radio frequency spectrum internationally and is binding on member states?
- ITU Radio Regulations (Correct answer)
- ITU-T Recommendation G.711
- ITU-R Report M.2083
- ETSI EN 300 220
Correct answer: ITU Radio Regulations
The ITU Radio Regulations is an international treaty that allocates frequency bands and sets operating conditions, binding on all ITU member states.
