Mobile Technology

Mobile Technology

Mobile technology is a collective term used to describe the various types of cellular communication technology. This includes phones, tablets, laptops, GPS devices, and any other technology that can conveniently be used on the go. Experts argue that this is the future of computer technology, as more and more daily tasks become doable on a cell phone or Smartphone.

Mobile technology is particularly growing in the field of commerce, as mobile payments and mobile shopping become increasingly popular. The mobile commerce ecosystem is projected to produce $119 billion in mobile purchases by 2015.

4G Network

One of the most important features in the 4G mobile networks is the domination of high-speed Packet transmissions or burst traffic in the channels. The same codes used in the 2G-3G networks is applied to 4G mobile or wireless networks, the detection of very short bursts will be a serious problem due to their very poor partial correlation properties. Recent study has indicated that traditional multi-layer network architecture based on the Open System Interconnection (OSI) model may not be well suited for 4G mobile network, where transactions of short packets will be the major part of the traffic in the channels. As the packets from different mobiles carry completely different channel characteristics, the receiver should execute all necessary algorithms, such as channel estimation, interactions with all upper layers and so on, within a very short time to make the detections of each packet flawless and even to reduce the clutter of traffic.
