The evolution of mobiles has been drastic in the last ten years. We’ve seen bar phones, flip-phones, phones with keypad and full touchscreen phones. Mobile companies have been laughing their way to the banks as a majority of the population is now connected through phones. The same goes with mobile networks, obviously mobiles and mobile networks go hand-in-hand, otherwise phones would have just been a brick with some buttons on it, imagine that. Well, that’s not the case and mobile network providers have constantly upgraded their services to provide the customers with a happy experience.If we talk about the evolution in mobile network technology, we can start with the age old 1G. Most people won’t recognize this, but when mobile phones were first launched in the market, they used to run on 1G. The ‘G’ stands for generation, so you can understand why it’s called 1G, 2G, 3G and 4G.1G belonged to the dinosaur era. It was an analogue network and worked similar to radio transmission. Calls on this network were susceptible to static and noise and anyone with a radio scanner could listen in to your calls. Scary isn’t it? However, it was an initial approach to cordless communication and could connect callers more than 40kms away. This was pretty impressive for those days.It marked the arrival of the digital network and a solution to the analogue network; it also meant the congestion of mobile towers throughout the vicinity. Digital cellular networks meant almost every other person had a phone and thus the era of ‘permanent connection’ began. Due to network towers, static and noise decreased drastically. But, the Global System Communication (GSM) system was limited when it came to coverage.
