4G is fourth generation technology and refers to the fourth generation of wireless standards. It is the successor of 3G. This technology provides ultra-broadband speed (gigabit power) to its Internet connection. This technology can work on stationary laptops or PCs or even mobile units. 4G technology has peak data rates of up to 100 Mbit/s. Home and business users can expect connections as high as 10 Mbps. It is said to be four times faster than 3G.
3G was yesterday's headlines. This standard was common a few years ago and was able to power up voice telephones, video calls and wireless data in an exclusively mobile environment. The main concern with this generation was providing excellent quality networking with improved spectral efficiency. 2G generation was first launched in 1991 through cellular telecom networks. This technological breakthrough saw digitally encrypted phone conversations and superior mobile phone penetration levels. This technology also saw the start of text messages and other basic mobile services. 2G succeeded what was later deemed as 1G, which had much to do with radio signals and analog communication. 2G was the digital breakthrough. Now we come to 4G-which is the epitome of fast, mobile online communication.4G Internet is not merely available for laptop and desktop PCs. This software and hardware is being installed on a variety of multimedia devices, including everything from car TVs to GPS systems to video game consoles and HDTVs. Using this technology makes downloading large files (like movies, online games, photos, presentations and audio files) fast and easy. You can see how this would revolutionize online communication; if everyone could take their desktop PC and cable model connection with them around town!
What are the technical differences between 4G WiMax and 3G, the previous generation? The frequency band of 4G is anywhere from two to eight GHz, while 3G is limited to 2.5 GHz. The data rate for 3G is up to 2Mbps, while 4G has the capacity for 100Mbps to 1Gbps. 4G offers extremely high downlink connections, both indoors and outdoors, unlike 3G. 4G can handle larger data packets in transmission with fewer errors. 4G also offers higher data rates, which means faster access to multimedia and video files. 4G Internet started in 2008 and is now peaking in the year 2010.
It's important to keep in mind that 4G broadband has a different operating speed, depending on if the unit is moving or if it is stationary. The more the unit moves (such as a GPS system, or a laptop in the backseat of a car), then the slower it gets. Stationary speeds are very high. However, even moving speed for 4G broadband is four times as fast as 3G systems.
Imagine being able to go to work and having complete confidence that you have everything you need. You can check your mail from your laptop, watch movies or send large database files to other associates in just a few moments. If you are looking for Internet services in your area, then don't be content with just broadband. Look for 4G Internet in your city!
