Cellular towers are tall structures that transmit and receive signals for mobile phones and other wireless devices. They are essential for creating a network that allows people to communicate over long distances. These towers connect to a network of base stations, which help manage the flow of data and voice calls. Typically made of metal, cellular towers can be found in various locations, including urban areas and rural landscapes. They are equipped with antennas that send and receive radio waves, enabling services like 4G, 5G, and Wi-Fi. The placement of these towers is crucial for ensuring good coverage and signal strength.
