E-GOLD currency known as the Internet age, is completely Internet-based online payment platform, created in late 1995. Has completely anonymous, fast, easy and completely crushed the concept of the geographical features and advantages, in just six years time, it has been a rapid development, more and more international companies and online stores began to accept E-GOLD payment way. It has become a powerful tool for e-commerce, including as Yahoo, Amazon, including many Internet companies have launched E-GOLD based payment transactions, is it more valuable as gold equivalent basis, completely divorced from any country's internal finances. Sohu Internet to listen to today honor from the Beijing University of Posts and Professor Lv Tingjie official channel of Sohu 3G conference keynote speech, as if sobering. But perhaps Professor Lv speech is too short, and many of which are personal or feeling confused, he just would not understand, write down the desired doubts. When the used field area is larger than the effective shielding range, it is suggested that more cell phone jammer should be adopted.
First of all, Lu said Professor of Internet and mobile Internet there are significant differences. Lu Professor said, the world's Internet is open, it is difficult to control and management, mobile communication technology is a strong management, strong control of the network. Therefore, based on communications technology for mobile Internet to the Internet as "off the reins of the horse" as pulled back, and pinch in the operator's hands. Meaning is not to say, operators of mobile communication technology to the development of the original open, difficult to control and manage the Internet for strong management and strong control. That being the case, then what is the development of wireless city do? Spend card online using mobile communication technology, is it not? WIFI or other mobile communications technology is not technology? The performance of mobile communication technology only on the phone? It is the 60W military communication backpackcell phone jammer.Or mobile phone Internet itself is Internet? operator what kind of technology through the pinch in the hands of the Internet? (the mobile Internet is mobile Internet). Then Lu Professor added: mobile Internet era, operators through strong technical background, can learn what it has done for each user, which summarized the the user's habits, preferences, etc., and thus provide for the needs of the user's personal , personalized service, so as to achieve accurate, effective delivery of business and service objectives. Also said some profound words. Mobile Internet era, operators will suddenly have a strong technical background in it? Do operators to create a still stronger than the green bar stuff. Is that the user what to do, including habits and preferences are under the control operator? Or is that operators in the "mobile Internet" on a good plan, "circle", the user in order to "mobile Internet" is only on the operator the "mobile Internet"? The power of each band ofcell phone jammeris 10watt with the total power of 40 watt.
Lu Professor iphone there is a theoretical model is not successful, only a small carrier and Apple are willing to cooperate. Also like to say these words and reality and not with whether. Since the iphone model can not succeed, AT & T how to do a good job then? AT & T is very small it? Very weak? Another of the most powerful people of China Mobile and Apple to talk about why so long? Why get on China Mobile's exactly like the iphone ophone it? cooperation and iphone how many operators are now? Professor Lv another example that when the iPhone app store is too active, because the bandwidth is limited, and its operators can not control, not management, channel width had been set, all the cars can walk in, the final outcome is led everyone dead, poor user experience. Bandwidth is limited, everyone knows, wired broadband is limited. As experience is poor, this can not say there. Just as we call, often encounter each other busy. Or for example I am using 2M of China Telecom's ADSL, presumably not low speeds, and can sometimes be difficult to access the website. Furthermore, after all, that the application is to store the user to use, do the each user will use the application? But also as an appointment as the days go to the market with get together? The future they should use the mobile Internet? Finally, Lu professor or firm to say "iphone model doomed to failure", and three years ago, said the. Now Nokia Ye Hao, Ye Hao of China Mobile, etc., in the cottage "iphone", nature will eventually fail. The output of antenna ofcell phone jammercan be adjusted from 0 Watt to 3Watt for each antenna.
Lu Professor three years ago, said the iphone mode to failure, why are iphone model has more fire? And eat crab, but more and more it? Implying are fools? Mere copycat? Questions raised too much, estimated to be very difficult to eleven doubts. In short, for operators, whether black or white, as long as the mobile Internet (tentatively so to speak, just as the mobile Internet on a) the cat is to give operators the benefit of operators are most concerned about. Mode with the iphone really does not work, then try ophone standards all right, do not try, how to know? Ancient once said a celebrity not do: There is no road, more people walk, they will become Road. For operators in the mobile Internet has not exactly profitable mode case, this sentence may be appropriate. Finally would like to mention one, I heard that now mobile MM also grow bigger way, and China Mobile's TD-LTE can reach 170M a recent test, can not wait for long, people can be in such a wide super-highway to close MM about the movement of water Lingling has. In order to move more gorgeously dressed Chula MM, MM development must not be destroyed during the delicate flowers Oh. "Mobile Internet users will exceed PC Internet users" - the judge is now estimated to have no doubt, the only uncertainty is just time. From 1.18 to 277,000,000, mobile phone users across the scale of this step is only a year and a half. Used to describe the explosive growth of mobile Internet users nearly a year of development, that is no exaggeration. This kind of GPScell phone jammerfits the large vehicle such as the truck.
2008, the scale of the development of mobile Internet users to enter a fast track, as of June 2010, Chinese mobile phone users reached 277 million, the overall penetration rate of Internet users has reached 65.9%. From this figures, with the explosive growth of mobile Internet is not to describe too. The rapid development of mobile Internet, for many reasons: first, a large base of mobile phone users as of June 2010 the number of Chinese mobile phone users has reached 810 million (Ministry of Industry data), which is the popularity of mobile Internet has laid a solid basis; In 2009, the official commercial 3G services is the growth of mobile Internet is an important thrust of the outbreak, 3G mobile Internet business has greatly accelerated the popularity of the concept for the development of mobile Internet provides a strong driving force; In addition, the falling prices of mobile terminals and function-rich, mobile Internet tariff reduction, but also greatly reduces the threshold of mobile Internet. In this combined effect of various factors, the emergence of mobile Internet users in the explosive growth of the scale. First article inspection will be carried out to cell phone jammer soon.

The transmission power of cell phone jammer phone

Relatively speaking, the installation method for exterior than “click install method” increased the cost of directional antenna. But also because it is to choose the directional antenna, all shielding scope of the basic confined within the building and building within a decade or two meters around for building outside unnecessary influence is relatively rare.
This type of installation method in practical application, first should be based on projected points will blockers and directional antenna installation in place, for all cell phone jammer blockers after open, in the building of the blind without signal detection in blind, if there is, sall adjust each blockers spotting spacing between or increase or decrease blockers quantity. Individual cases, may also require that blind construction for built to appropriately increase the internal situation of internal blockers patch points.
The installation method of cell phone jammer phone signal blockers selection is relatively broad, general and commonly used little power machine can choose, such as SMa – 818B, SMa – 818HB, SMa – 818C, SMa – 818HC, SMa – 818YB, SMa – 818W models all can.

   Laws 2.2.2 high-power blockers (60W above) stationing method
2.2.2.1 high-power blockers + directional antenna
If the target building need comparatively accurate and shielding, and need to minimize the impact on the target building periphery, conditions permitting, can consider cell phone jammer to use less number of high-power screen is + directional antenna to shelter to target the building it signal shielding.

 Laws 2.2.2 high-power blockers (60W above) stationing method
2.2.2.1 high-power blockers + directional antenna
If the target building need comparatively accurate cell phone jammer and shielding, and need to minimize the impact on the target building periphery, conditions permitting, can consider to use less number of high-power screen is + directional antenna to shelter to target the building it signal shielding.

High-power blockers usually refers to the transmission power of cell phone jammer phone signal in 60W above blockers, its cell phone jammer phone signals for the shielding radius with average of 50 to 100 meters (depending on weeks edge), such as base station of distance 818K60, SMa SMa – 818K100, SMa – 818K200 – cell phone jammer phone signal blockers high-power etc.
Cell phone signal blockers shielding signal in a transmission process, for the buildings, especially because of the reinforced concrete wall penetration ability is limited (attenuation larger), one side of the building in target direction and general hard 1 powerful blockers completely cover the whole building, all is usually to recommend in the building’s position on both sides before and after each corresponding erection a powerful blockers, for the whole building to achieve complete shielding. The diagram below:

The proposal aimed at these blind cell phone jammer area

Such “high-power blockers + directional antenna” approach before generally applied in goal for building a set of directional antenna auxiliary construction, such as, floor from right away before the limits (it is 20 to 50 meters) all have other building the side walls or roof can borrow to construct directional antenna. If no such right aerial, it should be the other buildings in the corresponding place USES vertical stroke to stem the way (as in the flagpole to erect antenna.
Use “high-power blockers + directional antenna” method, close to meet cell phone jammer a peripheral base station or aerial distance is not very ideal circumstances, may cause the top location or target building on both sides of the building with a few blind alleys, the proposal aimed at these blind area using small power blockers for points, namely: through the large and small power blockers do method of combining. Usually large and small power blockers in estimated quantity, can according to 1:2 or 1:3 proportion to estimate (1 powerful machine estimated 2 or 3 sets to replenish the blind area small power machine).

    
2.2.2.2 high-power blockers + omnidirectional antenna
If need to target buildings do, and overall shielding surrounding relatively open goal building, may overlook to target building surrounding influence, permitting conditions, can take cell phone jammer an examination with less number of trust in the high-power blockers + omni-directional antenna with to target the building to do signal shielding. The diagram below:

Such “high-power blockers + omni-directional antenna with” installation method, the several floors in target building no more than three layers of circumstances, can directly to the antenna mounted on all sides between the pentagon in position, and if the building roof above three layer, layer number is recommended cell phone jammer to the antenna mounted on all sides wall outside of altitude generally take the whole building, central high above a little bit wide offsets.


Use “high-power blockers + directional antenna” method, close to meet a peripheral base station or aerial height (position) is not very ideal circumstances, it can cause a large target floor of high-level position on either side of the building or leave a few blind alleys, the proposal aimed at these blind cell phone jammer area using small power blockers for points, namely: through the large and small power the method of combining blockers. Usually large and small power blockers in estimated quantity, can according to 1:2 or 1:3 proportion to estimate (1 powerful machine estimated 2 or 3 sets to replenish the blind area small power machine).
“High-power blockers + directional antenna” installation method is suitable for both need to target building indoor whole shielding, and need for building a certain peripheral range of open field into line shielding occasion.


In the building of 2.3 overall shielding
Many building in front and back into a list of cases, and no more than 50 metres before and after the interval when (depending on the peripheral base station of distance), between building and building a “power through to the antenna blockers + all the methods to achieve” complementary screen effect cell phone jammer , so can make full use of various blockers effectively screen radius, also the best possible saving blockers spotting quantity, concrete shielding effect schematic diagram shown below:

The building into a column of high-power blockers quantity needed is generally N + 1 (N for building number) building. While still need to consider a number of small power machine for blind spots.

The most common way is in every workshop cell phone jammer on both sides of a distance

2.4 aimed at factories, workshop
Match all is against 2.4.1 blockers to antenna
Factories, the workshop environment most are fully environment, in its internal achieving all cell phone signal shielding is relatively easy, the most common way is in every workshop cell phone jammer on both sides of a distance, each point by wall hung installed distance interval between 20 to 50 meters is generally, depending on the actual in pollen blockers effectively screen distance.
If internal plant have warehouses or toilet of lesser space such as regional, according to the wall alone against these conditions may need a small region of estimate alone shielding point bits.



With directional antenna 2.4.2 blockers
If the screen is required only for workshop in indoor, in factory workshop peripheral close has need not be shielded place, then need to be will all the blockers to antenna outfit and also into directional antenna in blockers selection on the cell phone jammer phone blockers choice model transmission cell phone jammer power can be adjusted.
Omni-directional antenna with directional antenna, due to the outfit directional antenna coverage area is relatively concentrated and reduced, and may in overall blockers point number has increased.

A common cell phone signal jammers installed Notes 1.1 The basic shielding installation notes to install a high degree of shielding device preferably not less than 1.8 meters above the ground. From the nearest mobile phone base station is less than 200 meters, shielding effectiveness is inversely proportional with the distance from the base station. That is, the closer the base station away from the shielding radius is smaller. Plug before tightening the antenna, the antenna on the subject of the antenna on the number and host number should correspond to the hole of the subject, do not plug the wrong, but not directly on the antenna does not pick the host power supply. 1.2 jammers standard method for installing the various components of the shielding device components generally include: host, antenna, power adapter. When installing the jammers, as the host and the peripheral antenna within a certain distance (usually 20-30 cm) there is a strong signal to the magnetic field. So that you can guarantee the blocking effect of cell phone jammer. And 220V power cord (strong power) around (usually 5-10 cm) have magnetic interference, therefore, how the various parts of the installation location to be placed on the critical, not positioned correctly, is likely to result in the emission signal interference shielding, impact shielding effect.
