Bluetooth Wireless Technology

Bluetooth wireless technology is a de facto typical, as well as specification for small low cost, short-range links between mobile PCs, phones and other portable devices, even home appliances. It will enable users to connect a wide range of computing and telecommunication devices easily and simple without the need to buy car or connect cable, it delivers opportunities for sapid and hoc connections, and the possibility of automatic, unconscious, connection between devices.

The Bluetooth wireless technology provide the means for the substitute of cables and infrared links that connect one device to another with a universal short-range radio link. Although this technology was originally developed for replacing cables, it has now evolved into a way to make small radio LANs.Bluetooth system is faster than mobile phones, including the upcoming third -generation, or 3G, high-speed wireless data Transmission.

Palm source popularized wireless device to device communication with infrared by putting an infrared port on every palm OS handheld. From the advent of the first palm OS hand heads in 1995 the ideas of “beaming” information become a cultural phenomenon. Business cards content and application began to move from one device to another with incredible ease. Now palm source is in owe ting again by pioneering and populisering Bluetooth in mobile devices .with this wireless technology entering the market in a myriad of Palm OS handhelds Palm Source is helping to create exciting new renue-genareting opportunitings for the palm economy.

Blu-ray Discs

A new technology emerged that brought digital sound and video into homes all over the world in the 1997. It was called, and it revolutionized the movie industry.
In 2006, the industry is set for yet another revolution with the introduction of Blu-ray Discs (BD). With their high storage capacity, Blu-ray discs can hold and play back large quantities of high-definition video and audio, as well as photos, data and other digital content.
A current, single-sided, standard DVD can hold 4.7 GB of information. That's about the size of an average two-hour, standard-definition movie with a few extra features. But a high-definition movie, which has a much clearer image (, takes up about five times more bandwidth and therefore requires a disc with about five times more storage. As Television and movie studios make the move to high definition, consumers are going to need playback systems with a lot more storage capacity.

MPEG-7

MPEG-7 is an ISO/IEC standard being developed by MPEG (Moving Picture Experts Group), the committee that also developed the successful standards known as MPEG-1 (1992) and MPEG-2 (1995), the MPEG-4 standard (Version 1 in 1998, and version 2 in 1999).
The MPEG-1 and MPEG-2 standards have enabled the production of widely adopted commercial products, such as CD-interactive, DVD.MPEG-4 is the first real multimedia representation standard, allowing interactivity and a combination of natural and synthetic material, coded in the form of objects.
MPEG-7 is formally called ‘Multimedia Content Description Interface’, a means of attaching metadata to multimedia content.
MPEG-7 is a standardized description of various types of multimedia information. This description will be associated with the content itself, to allow fast and efficient searching for material that is of interest to the user. The standard does not comprise the (automatic) extraction of descriptions/features.Nor does it specify the search engine (or any other program) that can make use of the description.
In other words: MPEG-7 specifies a standard set of descriptors that can be used to describe various types of multimedia information. MPEG-7 also standardizes ways to define other descriptors as well as structures (Description Schemes) for the descriptors and their relationships. This description (i.e. the combination of descriptors and description schemes) is associated with the content itself, to allow fast and efficient searching for material of a user’s interest. MPEG-7 also standardizes a language to specify description schemes, i.e. a Description Definition Language (DDL). AV material that has MPEG-7 data associated with it, can be indexed and searched for. This ‘material’ may include: still pictures, graphics, 3D models, audio, speech, video, and information about how these elements are combined in a multimedia presentation (‘scenarios’, composition information). Special cases of these general data types may include facial expressions and personal characteristics.

What Is needed to Build 4G Networks Of Future??

A number of spectrum allocation decisions, spectrum standardization decisions, spectrum availability decisions, technology innovations, component development, signal processing and switching enhancements and inter-vendor cooperation have to take place before the vision of 4G will materialize. We have the experiences of previous generations especially that of 3G, this will be useful in guiding the industry in this effort. Few factors that should be undertaken are as follows:-

Lower Price Points Only Slightly Higher than Alternatives

The business visionaries should do some economic modeling before they start 4G hype on the same lines as 3G hype. They should understand that 4G data applications like streaming video must compete with very low cost wire line applications. The users would pay only a delta premium (not a multiple) for most wireless applications.

More Coordination among Spectrum Regulators around the World

Spectrum regulation bodies must get involved in guiding the researchers by indicating which frequency band might be used for 4G.

More Academic Research

Universities must spend more effort in solving fundamental problems in radio communications especially multiband and wideband radios, intelligent antennas and signal processing. Standardization of wireless networks in terms of modulation techniques, switching schemes and roaming is an absolute necessity for 4G.

Integration Across Different Network Topologies

Network architects must base their architecture on hybrid network concepts that integrates wireless wide area networks, wireless LANS. Broadband wireless networks must be a part of this integrated network architecture.

Non-disruptive Implementation

4G must allow us to move from 3G to 4G.
