3G
3G stands for "Third Generation" mobile network technology. It was a significant improvement over older mobile networks, allowing people to not just make calls but also use the internet on their phones at faster speeds. While newer technologies like 4G and 5G have largely replaced it, many companies still maintain 3G equipment or need professionals who understand its infrastructure, especially in regions where newer networks haven't fully taken over. Think of it as one of the important stepping stones that helped create our modern mobile world.
