subject: What Makes 4g Wireless Internet Better Than That Which Came Before [print this page] You may be like many people who have to know how their new device or electronic gadget actually works, not content with simply using it. If you arent an engineer or electronic developer, the technical words and processes may not do you any good. Suffice it to say that Fourth Generation wireless Internet is as good as advertised.
You may be more familiar with the term 3G, which refers to 4Gs predecessor. However, as the name suggests, even 3G had two predecessors. The first generation of telephones was the kind first built back in Alexander Graham Bells era. This scheme is basically an analog system with no fancy bells and whistles. It got the job done. The second generation of phones was the digital telephone. You may have grown up using either of the first two generations of telephones. Then 3G came along and changed the game, giving you faster digital phones with Internet function.
Now, you have the opportunity to move into 4G, which offers you broadband speeds as well as better connection dependability. Now you are able to take advantage of the Internet completely on your cell phone anywhere in your city. Of course, the technology has moved into laptop usage as well. Now you can take your laptop with you around town as well, accessing high speed Internet wherever you happen to be in the city. The same technology is already available to a certain degree with WiMAX and Wi-Fi systems at certain higher speed caf wireless Internet networks. Now, 4G takes that development to a greater Internet speed capability.
Fourth Generation wireless Internet basically works by using orthogonal frequency-division multiplexing, or OFDM. What basically happens is a division of the signal into parallel data streams that are then transferred across radio channels, to be put back together at the other end. By dividing the signals and transporting them on separate radio channels, they can be sent much quicker. While uploading speeds are not made quite as fast as downloading speeds, both are dramatically faster than dial-up Internet and quite a bit faster than anything that previous Internet technology could offer.
Of course, keep in mind that the maximum speeds advertised by any Internet method are those that can be expected only in optimum conditions. In the real world, the speeds are not as fast. Practically speaking, your signal still has to cross through storm clouds, rain, trees, and other obstructions such as buildings. The speeds you actually enjoy are not as fast as what is technically available. However, that is true with just about any Internet access method. Optimum conditions are never attained in the real world.
Technical words and connection speeds aside, 4G wireless Internet is positioned to offer you dependable high speed Internet wherever you may be in the city. The benefit of this is hard to qualify in numbers or statistics. The effect is felt in the ease with which you connect to high speed Internet whenever you want. The benefit is felt when you are able to access dependable Internet while staying mobile. It is felt when you do not have to wait minutes for simple pages to download on your laptop or cell phone, or when you are able to perform more complex online functions without missing a beat.
