4G refers to the fourth generation in cellular wireless technology standards. It is the successor to 3G, which has been the standard for cellular wireless technology till now. Each generation represents a dramatic shift in the technology and nature of the service, with the first generation (1G) being analogue, the second generation (2G) marking a step into the digital domain and the third generation (3G) bringing in advanced features like multimedia support and higher speeds. And now 4G looks to redefine the service yet again with gigabit level speeds and other advantages.
While there are a lot of technical changes in 4G, a major one being that unlike 3G it will be based on packet switched switching only, most consumers need not worry about that. To them, what will matter is what 4G brings to the table. And what it brings is an array of never before seen features and conveniences.
* Blazing Speed: - While 3G offers a frequency band of 1.8 - 2.5GHz, 4G can give you a range of 2 to 8 GHz. And data rate speeds? Well with 3G, it was limited to 2Mbps, whereas 4G speeds can range from 100 Mbps while moving to 1 Gbps when stationary. That means no more waiting for mobile Youtube to buffer.
* Internet wherever you go: - VSF-OFCDM and VSF-CDMA standards that are incorporated in 4G will allow high speed uplink and downlink no matter where you are. This means uninterrupted internet on your mobile.
* Fewer disruptions: - The FEC technology, or Forward Error Correction used by 4G allows for larger data packets, reducing the error rate. The end result is a noticeable increase in data through - put.
4G is quickly replacing 3G as the default wireless standard. A recent survey found out that in a few years, more people will be accessing the internet through mobile devices rather than desktops. No doubt 4G is paving the way for that.
