Mobile 301 – Part 1: Mobile 4G & Beyond

In the last chapter, we discussed the evolution of mobile technology, and the benefits that each generation gave us: 1G invented mobile, laid the groundwork for coverage, and proved it was possible to make and receive calls while on the go, but on a limited basis. 2G brought mobile to the masses, increasing voice capacity so billions of customers could enjoy mobile calls. 3G introduced mobile broadband, increasing network capacity and making it more efficient for data, which made mobile devices more like mobile computers. And that brings us to 4G LTE. 4G LTE builds upon 3G mobile broadband, providing faster, virtually instantaneous internet connections. With 4G LTE, users can stream HD video with minimal buffering, download apps and multimedia with blazing speeds, browse the web faster than ever, and conduct real-time, high-quality video chats. And because 4G LTE works hand in hand with 3G, it can deliver these amazing mobile broadband user experiences with reliable coverage worldwide. As you can see, life moves faster with 4G LTE. And more and more, the world of mobile communications NEEDS it. Why? Think about it like this: Every single day, the world of mobile communications grows, with over a million new smart phone users joining the ranks every day. And each of them wants and expects that every mobile device they use will be able to do everything from loading a webpage (animation shows that loading a webpage takes .0014 GB) to streaming full HD movies (Animation shows that streaming an HD movie takes 5.93 GB). And now, remember that mobile communications, from the very beginning, has been dealing with the issue of capacity. There is only so much frequency, or spectrum, to go around, to service this incredible and ever-growing demand. That’s where 4G LTE comes in. Now that you know a little about all of the advances of the past, It’s time to jump ahead to today. First, we’ll discuss all of the innovations and breakthroughs that have granted 4G LTE its blazing fast speeds and data rates. Then, we’ll tell you how 3G is also constantly improving to deliver faster speeds, and work together with 4G LTE to deliver seamless mobile broadband services with coverage virtually everywhere. Finally, we’re going to lay out all of the practical advantages that 3G and 4G LTE provide, so you can see how 3G and 4G LTE deliver the amazing mobile experiences we have come to love. Let’s dive in.
