Cell towers are key for sending calls over long distances in a cellular phone network. They have antennas and radio gear that let phones connect. There are many types, like panel and sector antennas, each designed for better coverage and capacity1.
Cell towers do more than just send signals. They receive calls from phones and send them to a switching center. This center connects the call to another phone or network, making calls possible locally and worldwide2. Inside each tower, a Base Transceiver Station (BTS) handles calls and does important tasks like signal processing and encryption1.
How far cell towers can reach depends on many things. In the countryside, they can go up to 20 miles. But in cities, it’s usually just a mile or two because of things like signal strength and tall buildings1. New tech like MIMO and beamforming helps them reach farther and improve signal quality1.
Cell towers are crucial for good wireless communication. They need a clear line of sight for strong signals, especially for 5G technology1. Phones work like radios, sending and getting signals to and from cell towers. Signals sent by phones are called uplinks, and those sent by towers are downlinks2.
