Sea Area A1 uses which type of communication technology?

• A. VHF-FM range
• B. MF/HF long-range
• C. Satellite communications
• D. Inland waterway signaling

Answer: (A)

Sea Area A1 relies on VHF-FM communications because this zone is covered by shore-based VHF transmitters that provide reliable line-of-sight coverage along the coast, in ports, and through near-shore routes. VHF offers clear, fast voice communication between ships and shore facilities, which is ideal for near-shore traffic, safety coordination, and routine operations. Longer-range needs, such as crossing open seas or relying on global reach, would require MF/HF or satellite systems, which are designated for other sea areas. Inland waterway signaling is aimed at rivers and canals, not sea areas. So, the technology used in Sea Area A1 is the VHF-FM range.
