But what Exactly are 4G Networks?

No matter where you live, you can expect that faster, more powerful 4G networks will eventually arrive, heralding a new era of mobile Internet access. Currently, 4G systems aren't really all-IP, simply because there's still lot of overlap between 3G and even 2G networks throughout various countries and around the world. You still won't catch me fielding phone calls while I'm trying to catch largemouth bass. To send and receive packets, first your phone has to communicate with a base station. There are a lot of different methods (called air interfaces) to establish a link between the base station and phone. It is, in business parlance, what's called a constraining resource. To do that, service providers (called carriers or operators depending on your location) are investing heavily in their infrastructures, meaning the hardware and software that makes cell communications possible. LTE networks are called long-term evolution because carriers want to stick with this technology for a long time, rather than blow scads of cash to upgrade infrastructure every few years.

A 4G LTE (Long Term Evolution) tower, however, can serve around 300 or 400 people. LTE uses OFDM (orthogonal frequency division multiplexing), which divides a signal into parallel data streams that travel radio sub-channels. Unlike 3G, however, 4G uses IP even for voice data. 4G, however, will realize the mobile Internet dream. 3G networks began spreading in the early 2000s, and with them, so too did the concept of mobile Internet.

We'll steer you through the acronyms and the marketing convolutions and guide you past the skyscrapers of techno mumbo-jumbo. Those are theoretical data rates that won't happen in the real world anytime soon. Although you likely won't see stream HD video anytime in the next few years, 4G will enable glitch-free video calls, YouTube videos, and more. Thus, carriers that want to provide the more reliable and speedy service lust after spectrum in lower frequencies. By contrast, higher frequencies work in a line-of-sight fashion and they're more easily scattered by random objects and other interference. To win more subscribers, carriers try to build the fastest networks with the greatest geographical and population coverage. Carriers go to battle with each other for that limited spectrum.

Those with spectrum access can provide the best reception for their customers, and thus haul in more subscribers and revenue. The challenge for engineers and programmers is to pack as much digital data into each radio signal, thus maximizing the speed and efficiency of the network as a whole. By comparison, 4G could shift things into high gear, at around 3 to 5Mbps; that's roughly the speed that many home computers receive via cable modem or DSL. What your suffering smartphone really needs is the kind of broadband (high-speed) Internet service that you tap into on your home computer. With a 3G tower, about 60 to 100 people can share the signal and get fast, reliable service. You're lost in a city of 6 million people. Still under development, this standard could make your current 3G smartphone 100 times faster. Even with 4G, my smartphone still has an Off button.

3G vs. 4G, What is the Difference? For example, imagine that you're waiting for the kids to finish their shopping at the mall and you want to watch a football game on your phone. Because 4G signals are sparser than 3G, phones expend more power searching for 4G reception, meaning you might not even get a single full day out of your phone. And for the first time, they are getting smart enough to fix themselves. But thanks to sensors and advanced software, a 4G system has self-healing capabilities that let it route traffic through other towers until repairs are made. Then consumers began clamoring for even more fabulous, Web-centric mobile capabilities. And then you buy a map at a gas station. Camping in the wilderness and you forgot to buy Tom Petty concert tickets? With 3G networks, this kind of ubiquitous data is often spotty and exasperating to use. In the meantime, network infrastructures began creaking under the weight of immense demands for data. Post was gen er ated with GSA Con tent​ Generator D em​ov​ersi on!
