📱 How Does a Cellphone Work?

https://youtube.com/?si=Wyfa2rsQ_eiQzOF6

Have you ever wondered how your voice reaches someone on the other side of the world in just a few seconds?

A cellphone converts your voice into digital data, sends it as radio waves to the nearest cell tower, routes it through the mobile core network, and finally delivers it to the receiver's phone, where it is converted back into sound.

Modern mobile communication is made possible by components such as the antenna, processor, modem, SIM card, battery, and mobile network.

📡 What is a BTS?

A BTS (Base Transceiver Station) is the equipment that connects your mobile phone to the cellular network. It transmits and receives radio signals, making calls, SMS, and mobile internet possible.

In Ethiopia, mobile networks such as Safaricom Ethiopia and Ethio Telecom rely on BTS sites to provide 2G, 3G, 4G, and 5G coverage.
