If the operator and signal person cannot see each other, what method can they use to communicate?

In situations where the operator and signal person cannot see each other, the use of radios is an effective method of communication. Radios allow for clear and direct verbal communication over considerable distances, making them suitable for scenarios where line of sight is compromised, such as in construction sites or when working on telecom towers. This type of communication helps ensure that instructions, safety protocols, and any urgent messages can be conveyed quickly and efficiently, minimizing the risk of misunderstandings or accidents.

While walkie-talkies, often considered a type of radio communication, can also be effective, they typically have limitations in range and clarity when compared to standard radios, especially in noisy environments or over longer distances. Hand signals might be useful when both parties are in view of each other, but they are ineffective if visibility is lost. Lights signaling is less commonly used in most telecom operations, as it requires specific conditions and understanding of the signals being used, which may not be practical in all work environments.
