3G (Third Generation)

3G (Third Generation)

Introduction

Launched in the early 2000s, 3G networks were the first to enable mobile internet and data services at a commercially viable scale.

Key standards include UMTS (Universal Mobile Telecommunications System) and CDMA2000.

Speed and Capabilities

Offered data transfer rates of up to 2 Mbps, with typical speeds around 384 kbps.

Enabled basic mobile internet browsing, email, and multimedia messaging.

Impact

Marked the beginning of widespread mobile internet use, allowing for the development of early mobile applications and services.

Supported video calls and mobile TV.

4G (Fourth Generation)

Introduction

Launched in the late 2000s to early 2010s, 4G networks introduced significantly higher speeds and lower latency.

Key standards include LTE (Long Term Evolution) and WiMAX.

Speed and Capabilities

Provided data transfer rates up to 100 Mbps for mobile use and 1 Gbps for stationary use, with typical speeds ranging from 5 to 12 Mbps.

Enabled high-definition video streaming, online gaming, and more complex mobile applications.

Impact

Revolutionized mobile internet by supporting applications that require higher bandwidth and lower latency, such as streaming services, real-time multiplayer games, and advanced mobile apps.

Led to the development and proliferation of smartphones and mobile computing.

5G (Fifth Generation)

5G (Fifth Generation)

Introduction

Began rolling out in the late 2010s, 5G represents a substantial leap in wireless technology.
