🔍 Key Concepts

• Satellite communication frequency bands commonly used for maritime services (L-band, S-band, etc.) • General knowledge of Iridium as a low-earth-orbit (LEO) satellite system and its typical operating band • Difference between VHF/UHF ranges and L‑band used for satellite phones

💭 Think About

• First, identify which of the listed ranges fall within the typical L‑band used for many satellite communication systems. • Compare each option to see which one is most often associated with LEO satellite phone services rather than terrestrial mobile or other services. • Think about whether Iridium handsets are designed to work through the atmosphere with minimal attenuation; which frequency range is best suited for that?

✅ Before You Answer

• Verify which of the choices falls into the L‑band (around 1–2 GHz) region commonly used for satellite telephony. • Consider which bands are more commonly used for cellular networks vs. satellite systems. • Eliminate any bands that are typically associated with radar, Wi‑Fi, or non‑satellite maritime uses, leaving the one that matches known Iridium specs.
