The 3G tablets have given way to the latest and most advanced tablets- the 4G tablets. The major difference between 3G and 4G technologies is the supersonic speed with which web browsing becomes a delight. With the speed at which you can access the Internet with 4G tablets, it is difficult to switch back to the 3G ones. A 4G tablet offers a download rate of 30,000 kbps. Tablets are primarily used for high data consumption such as online e-reading, watching videos and video conferencing. They are different from smart phones in that you cannot make calls or send text messages. Even though 4G is an extension of 3G technology, the 4G technology is about to introduce new dimensions in data transmission with a speed that may reach up to 5 gigabytes per second.
4G technology has been kept free from circuit design and it relies more on the packet design thus achieving data transfer in nanoseconds. The main feature of 4G is that it relies on spatial multiplexing. This is primarily a smart antenna system used by ITU (International Telecommunication Union) that is used in the deployment of data transmission and receiving. By using a number of antennas, there is a remarkable increase in the speed and facilitation of the data transfer process. Here are the most recent 4G tablets that are worth a definite look:
