What is a characteristic of areas classified as 'Digital Sea Areas'?

Digital Sea Areas are defined locations where specific protocols and technologies are employed to enhance maritime communication, particularly in emergency situations. One characteristic of these areas is their role in determining the range of emergency communication. This means that within these areas, certain telecommunications equipment and procedures are established to ensure effective and reliable communication during emergencies.

The designation of the area directly impacts how maritime operators can deliver distress signals and communicate critical information to authorities. This is crucial for ensuring the safety of vessels and personnel in maritime environments.

Understandably, the other choices do not directly relate to the primary function of Digital Sea Areas. While these areas might involve specific operational requirements or equipment, the main defining characteristic being highlighted is their influence on emergency communication capabilities.
