A Signal Tower is a structure used for communication, often found in areas where visual signals are necessary. These towers can transmit messages using flags, lights, or other visual signals, allowing for long-distance communication without the need for electronic devices. Historically, they were crucial for maritime navigation and military operations, helping ships and troops coordinate movements. In modern contexts, signal towers may also refer to telecommunications towers that support antennas for mobile phone networks. These towers facilitate wireless communication by transmitting radio signals, enabling people to connect through their devices. They play a vital role in maintaining connectivity in urban and rural areas alike.
