• 1G: Introduced in the 1980s, 1G was the first generation of wireless communication, providing analog voice communication. It laid the foundation for the development of mobile phones, although its data speed and reliability were minimal compared to modern standards.

• 2G: The 1990s saw the birth of 2G networks. It marked the transition from analog to digital communication, enabling voice calls, SMS (text messages), and basic data services. GPRS (General Packet Radio Service) and EDGE (Enhanced Data Rates for GSM Evolution) were introduced later to enable faster data transmission.

• 3G: Launched in the early 2000s, 3G networks allowed for greater mobile internet capabilities. With faster data speeds, users could browse the internet, watch videos, and use GPS-based services on their mobile devices. This era also saw the introduction of smartphones.

• 4G: By 2010, 4G technology became widespread, delivering speeds up to 100 Mbps. It supported high-definition video streaming, gaming, and a wide array of apps, laying the groundwork for the digital economy. LTE (Long Term Evolution) became synonymous with 4G, though advanced LTE iterations (LTE-A) still couldn’t meet all data demands.

• 5G: In 2019, 5G began its global rollout, promising speeds up to 10 Gbps, which is 100 times faster than 4G. With ultra-low latency and greater bandwidth, it supports new technologies like IoT (Internet of Things), AR (Augmented Reality), and VR (Virtual Reality).

Key Technologies Behind 5G

5G isn’t just a faster version of 4G; it's built on a completely new technological foundation designed to provide massive improvements in speed, latency, and connectivity. Several core technologies make this leap possible:
