The calculation of shielding range of cell phone jammer

The whole covering range of all base stations influenced by    cell phone jammer      equal to the integral arrangement of adjacent regular hexagons. Although GSM has made a huge commercial success, but its technical limitations to the capacity has been limited, making it cost in the system and CDMA system in the future will compete at a disadvantage. It should be noted, GSM's success is largely due to CDMA products were not mature enough in key technologies (distance effect, power control, etc.) there are obstacles, coupled with the success of the European decision-making in the standardization work, only the GSM Born on the When, as in the early 1990s, analog cellular telephone system upgrade only option to obtain a rapid spread of the world. China already has the world's first large-scale telecommunications networks, but the size of the telecommunications industry is not the largest. Explore new telecommunications business growth, to grasp the future direction, 3G is the greatest significance. Actual working range of every base station influenced by    cell phone jammer      is the regular hexagon (also known as the cell).
Currently, around divergent views on the timing of 3G development, mainly due to the current development of 3G is not so urgent, so allow a lot of views exists. If you need to do to a unified conclusion, the state will have a very practical, considering the many factors that the implementation plan. Steady development of China's need for 3G, in global terms, even if the license has been issued in Europe, nor to all the human and material resources to go 3G. According to the study of the situation in Europe, the development of 3G in Europe is not completely unified view. Basically, many operators and manufacturers in a positive way to keep track of 3G, and the development of 3G, but are in a relatively passive. Because the 3G business model, profit outlook is not so clear. It is the calculation of shielding range of    cell phone jammer .
With the development of information society, the rapid popularization of Internet applications, the demand for high-speed data transmission has become increasingly urgent in the wired communications network, data traffic has been a worldwide trend to catch up voice communications. Expected in the mobile communication network, data traffic will also be in the near future than voice traffic. The formation of an integrated global broadband multimedia mobile communication network will be the trend, wireless transmission of data will greatly expand the people's living and working space; and this trend will also allow the integration of global broadband communication systems ─ ─ wideband CDMA quickly from experimental room into the practical stage, its application will enable the integration of global broadband multimedia mobile communications can be achieved. The cell phone facilitates people’s life but   cell phone jammer      is still needed.
Optimistic estimates, next year China Unicom will launch CDMA, which communications equipment manufacturers, that means a new competitive platform, the competitiveness between the companies will therefore be considered. CDMA was China's "863" key projects, as early as 1994-1995, the authorities of the technical staff began to research its key technology in 1997, Great Wall in Beijing, Shanghai, Xi'an, Guangzhou, established four commercial experimental network. Since the experimental nature of the network, so its growth rate is not fast. Two years ago the company announced the development of China Unicom CDMA, but only until August 2000 becomes clearer, CDMA in China painstakingly. Today, China is still in the analog wireless networks, GSM and narrowband CDMA coexistence phase. Which is gradually declining TACS, GSM momentum is busy (now about 95% of users are GSM network), CDMA is gradually put into commercial use. The cell phone threatens the confidential information safety so that   cell phone jammer is needed to prevent this phenomenon.
