Mobile Technology
Mobile technology is a collective term used to describe the various types of cellular communication technology. Mobile CDMA technology has evolved quite rapidly over the past few years. Since the beginning of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a cellular phone, GPS navigation system, an embedded web browser, and Instant Messenger client, and a hand-held video gaming system. Many experts argue that the future of computer technology rests in mobile/wireless computing.
4G networking
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 will be applied to future 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 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 flawlessly and even to reduce the clutter of traffic.
