Mobile devices use cellular networks, also known as mobile phone networks. These networks allow users to communicate and access the internet wirelessly.
Cellular networks use radio waves to transmit data between mobile devices and base stations. These base stations are connected to the internet via fiber optic cables.
There are different generations of cellular networks, each offering faster speeds and greater capacity:
- 1G: First generation, analog networks, limited data transfer.
- 2G: Second generation, digital networks, introduced SMS and MMS.
- 3G: Third generation, faster speeds and data services, introduced mobile internet.
- 4G: Fourth generation, significantly faster speeds and data services, introduced mobile video streaming.
- 5G: Fifth generation, fastest speeds and low latency, enabling new applications like autonomous vehicles and virtual reality.
The specific type of network used by a mobile device depends on the device's capabilities and the network coverage in the user's location.
