There is a great buzz in the world of wireless communications. Everyone is talking about 4G. What exactly is 4G, and how will it impact us?
4G is just the short acronym for Fourth Generation technology for mobile communications. 4G is the “next” generation technology that will be used by cellular phone companies and internet service providers to deliver superior quality video and data apart from voice.
Interestingly, the 3G (third generation) technology is not yet operational in most countries. Many like India for example are using the 2.5 G technologies for mobile or cell phones.
In next section we shall discuss in how these technologies evolved over the last two decades. |
