Introduction This article focuses on the European wireless Mobile Industry, and development and Japan. WiFi (WirelessFidelity) 802.11b technology is not in the scope of discussion, because the use of the standard surface is small and limited support for mobility, making it less suitable as a platform for mass mobile audience (although, in theory, you can 802.11 b on multicast). This article discusses the mobile network technology, attention to personal handheld devices and / or in the vehicle in the large-scale audience allocation Multimedia Content (entertainment, news, Security Information, etc.). This article will look critically at the background of the various technology and market and regulatory issues. The absence of specific field data (except for prototype testing in addition), which is mainly qualitative comparison, and selection of different order of ranking techniques. Market Based on the basic content types, market observation, ground Service Transition to the mobile (voice Broadcasting , Voice, followed by e-mail) the success, all with a simple fact about: Mobile TV The next generation of "macro markets" of a branch. Research shows that mobile TV consumer response has been positive. Interestingly, in different parts of the mobile TV audience watching, the reaction is not much difference. However, the existing demand, such as news and information, the user can not easily be pointed out that the reason they use the service. The researchers noted that further studies need to use a broader definition of television form, because the research is based on the existing fixed television programs. Broadcasting standards such as DVB-S and DVB-T, its inherent advantages of a fixed terminal to transfer video and audio signals. This move resulted in the gradual transfer market but the impact is undeniable. U.S. XMSatelliteRadio examples show that even satellites can effectively transfer to small mobile terminals. Transmit video and audio content in the analysis of real time operating costs and service quality, such developments are changing the mobile operators network mode of decision making. Present, a series of very complex business and strategic moves under way, different cultures Telecommunications And the entertainment industry has been the first step out of joint. Searching for new competitors in the mobile Public When the media market model, with some new discovery, such as "personalized mass market" and micro-marketing. In regard to the changing nature of the content broadcast, the "personalized program" (from the program choice and the time point of view) with the mass transfer is no longer mutually exclusive concepts. A more special but important market for wireless mobile multicast, the military. The United States has strongly invested in a satellite multicast platform, known as the Global Broadcast Service (GlobalBroadcastService, GBS). The design objective is to spread widely around the low-cost terminal "pushing" a lot of intelligence, weather and other information. For the industry, DVB Project Office three years ago, noticed the DVB-UMTS integrated system of possibilities, and established a special working group to study this area. The main objective of this working group Package Including, with the UMTS Forum and 3G Standards Organization 3G PP Closer ties to assess this area of international research projects, and the definition of the two systems share some key elements. Network diagram Figure 1 sets out the four most important commercial wireless solution (for fixed and moving terminals) and the two most important performance indicators (bandwidth and Geography Cover) relationship. Surprisingly, you can see that compared with other technologies, 3G has its limitations, including the ideal geographical coverage is limited (may not have 3G service providers villages, accounting for about 80% of the area of the world). Figure 1, the size and bandwidth of wireless technology Geographical Cloth Relationship I am an expert from china-dental-supply.com, while we provides the quality product, such as Dental Laboratory Equipment , Dental Screw Post Manufacturer, Dental Hand Piece,and more.
