Mobile phones communicate with cell towers, also known as base stations, which transmit and receive radio frequencies. These towers are part of a network that connects to the broader telecommunications infrastructure, allowing for voice calls, text messaging, and data services. The frequencies used vary by region and network technology, including GSM, CDMA, LTE, and 5G. Each tower typically covers a specific geographic area, known as a cell, facilitating seamless mobile communication as users move from one cell to another.

How does a mobile send and receive sound?
Mobile phones, like radios, transmit digital electronic signals that are converted back into sound at the receiving end. For cell phones, the transmission is in the UHF (Ultra-High Frequency) band, hence very limited in range compared to CB bands and broadcast radio. The frequencies for civilian phones and data transmission are discrete blocks ranging between 700 to 2700 Mhz.
