Mobile 201 – Part 1: 1G to 4G Evolution

Take a second and think about your smartphone. Have you ever really considered just how amazing it is? The things it can do would have been inconceivable just a few years ago, and the technology is improving all the time. Mobile technology has matured quickly and significantly over the years, and with each wave of improvements, the world has gained access to smaller, more powerful devices that connect to faster networks and deliver greater capability. We’ve somehow gone from this…to this (will animate very old to current technology) And when the innovations aren’t just minor improvements, but instead, fundamentally change the world, we consider those innovations to be the next Generation. With new technology innovations, come questions that need to be answered. Questions like, “Why is this one better than that one?” “What makes this faster?” “What does “G” mean, anyway??” What’s the difference? Now we could simply say “it's just faster” or “better” and that would be true. But sometimes, understanding WHY newer technology is faster, and HOW it is better, can be the difference between choosing the right mobile device, and not. And the only way to really understand the WHY and the HOW is to start at the beginning: understanding the evolution from 1G to 3G and 4G LTE, and all the amazing technical achievements that made it possible. So that's what we’re going to dive into right now. Building on what we learned earlier, we’ll discuss: How 1G established Coverage and allowed calls to be made on-the-go. How 2G delivered more Capacity and created a world where everyone could have a mobile phone. How 3G turned mobile phones into mobile computers by introducing fast, broadband data. And now, how 4G LTE complements the mobile broadband services of 3G, boosting data capacity to support richer content and more connections. So let’s take a quick look back at how we got from where we were to where we are today.
