Or some of the busiest section of the district traffic and TCH channel is not enough to produce the Assignment Falure (TCH assignment failure) by the TCH congestion. These are TMSC1 not received the news of the end office to send back the ANC (ANN). So, long distance, then switch rate is a very comprehensive assessment indicators, can scientifically measure the overall quality of the GSM network. Paging success rate and long distance, then switch rate are closely related. The general said the level of the Paging success rate and long distance, then switch rate the level of the corresponding relations. Wireless coverage, the base station simply Paging less than a cell phone; if SDCCH congestion, the phone grab less than a dedicated channel to the hair to the base station on the Paging the Response.The control of  cell phone jammer  is performed by buildings
In addition to the individual hot spots, for the time being can basically meet the need. Zhejiang Telecom GSM 5, expansion of the GSM network frequency range: 898.6 ~ 908.8MHz, a total of 10.2MHz. A network band extends to 885.0125MHz GSM network bands down extended to 14.4MHz 23 to 94 frequency points in the six expansion principle. At present, Zhejiang Telecom G base stations in many areas has been very intensive, particularly the three cities of Hangzhou, Ningbo and Wenzhou, part of the distance between the base station is only four or five meters, the selection of suitable sites for has become increasingly difficult. Stand too close, resulting in the same frequency and adjacent channel interference increases. In addition, the higher the antenna gain, the narrower its beamwidth in the vertical plane.The management of  cell phone jammer  can be implemented by sections
RF frequency hopping, power control, continuous emission, antenna diversity techniques, in order to reduce interference; without changing existing network infrastructure. However, despite the high utilization of this approach frequency, but the system interference increases, such as using anti-jamming measures are not effective and may have a greater impact on network quality and should therefore be used with caution. Concentric circles technique is usually the district is divided into the outer layer (Overlay) and inner (underlay), the outer layer of coverage for traditional honeycomb cell, while the inner layer of the coverage is mainly concentrated near the base station. In addition, the inner and outer layers of the frequency reuse coefficient is generally different from the outer layer of the general 4 × 3 reuse, while the inner layer closer to reuse, such as 3 × 3,2 × 3 or 1 × 3, etc. .  cell phone jammer  can be used for 24 hours 365 days continuously.
Depending on the implementation of concentric circles can be divided into ordinary concentric circles with the smart two kinds of double-layer network (IUO), the main difference between the two is that the transmit power of inner and outer layers of the inner switching algorithm.

First to determine the coverage area. The purpose of the indoor coverage requires field strength coverage, while the base station signal radiation area provides an ideal signal coverage inside buildings. Therefore, the primary work of the engineering design survey to determine which areas of the base station coverage, which areas need to indoor distribution system to enhance the signal. When the investigation, should pay special attention to the traffic in busy areas, that is the most frequently used mobile phone, often in this region to design a distributed antenna. Then forecast to cover the effect to determine the engineering program. The site investigation will be basically to determine the distribution of the antenna position, and to determine the jurisdiction of each distributed antenna output power of each channel. So that the problem of cell phone jammer can be found out timely.
In order to make program planning more accurate field strength coverage prediction, often these areas. Specifically can take the following methods: emission unit with a signal generator and an indoor antenna group, issued the design of the corresponding output power in a distributed antenna location, will test the phone as a receiving unit, the corresponding coverage area test field strength, size, observe whether a good signal is received. Project has a good cost performance, engineering design needs to be selected to put a lot of the right uniform point distribution system. At this point, make sure that the system put a lot of all the parameters have been obtained so you can select the suitable interior uniform point distribution system construction. If the area of the examination is big, the high power cell phone jammer should be used.
China's mountainous wide expansion project to the construction of new base stations. Economically developed cities, towns, the number of users, large and obvious economic benefits, and for the economically less developed county, township, number of users is small, the large investment in the construction of base stations, not economic. Even in the modern city, tunnel, subway, underground shopping malls, parking and enclosed large buildings, due to the shielding effect of the mountains, the ground and buildings, mobile communications the weak letter points or blind spots, if construction of base stations in these small areas, it will cause a serious waste of financial resources in the spectrum resources.

cell phone jammer is adopted to scare the dangerous animals away

Energy supply. Arc welding process to consume large amounts of electrical energy through a variety of welding power source to supply energy. The most common welding power source includes a constant current source and constant voltage power supply. In the arc welding process, the voltage applied to determine the length of the arc, the input current determines the output of the heat. Constant current power output constant current and voltage fluctuations are used for manual welding, manual arc welding and tungsten inert gas shielded arc welding. Because the current manual welding requirements remained relatively stable in the actual operation, the electrode position is difficult to ensure the same arc length and voltage will also change. Constant voltage power supply output voltage and constant fluctuations in the current.  cell phone jammer  is adopted to scare the dangerous animals away.
Therefore commonly used in automatic welding processes such as MIG arc welding, flux cored arc welding and submerged arc welding. These welding processes, arc length remains constant, any fluctuations occur because the distance between the welding head and the workpiece through the current changes to compensate. For example, if the welding head and the workpiece interval close to the current rapidly increases, making the solder joint at the heat surge, melting of the welding head section until the interval to restore to its original level [12]. The type of electricity used has a great influence on the welding. Power-welding process, such as the protection of the manual metal arc welding and MIG arc welding commonly used direct current, electrode can be connected to positive or negative. Welding, then the positive part will have a greater heat concentration.  cell phone jammer  is utilized to indicate the direction.

Shipping Description of cell phone jammer

WAP portal with ads, and built-in advertising compared to advertising messages and voice class is the mobile phone advertising is still the most important form of advertising, but many times these ads will allow users to feel resentment, because it is the user most of the time not willing to push the case to force the user not only unwilling to accept, but also there is a reject, so even users with rich resources, operators will inevitably have to face the licensing mechanism. Establishment of mobile advertising user license mechanism, for consumers to decide whether to accept mobile advertising information, rather than passively, to accept the mandatory advertising information, not only can improve the recognition and perception of users, but also can enhance the precision marketing. A specific shielding position of cell phone jammer should be added for the signal dead zone.
According to Japan's successful experience, mobile advertising operations must be based on a strict licensing system, based on that advertisers and operators must obtain permission under the premise of the user to carry out advertising and marketing. We mentioned above the Japanese I-MODE mode often give away and receive calls in the form of value-added services to the users to watch the mobile advertising to compensate, in order to attract users to watch mobile advertising. In addition, Japan's regulatory authorities also introduced a number of specific provisions and penalties to ensure that mobile advertising must be sent in the user license basis. However, mobile advertising license in China to establish a mechanism can not be completed overnight. Mobile advertising itself as a strong technical, to establish licensing mechanism first breakthrough in technology, while China's current technology has not yet reached this level.

 After all, unlike the PC Internet, mobile Internet advertising model can produce benefits depends on how much to tap phones and mobile phone users of this medium is characterized by this group. As the subject screen and other reasons, SMS mobile advertising became mainstream in the form of Internet advertising, but this "push" mode so that users hate, and the results are not satisfactory. Really suitable for mobile Internet in the form of advertising to be explored. From the Japanese situation, there are two types of advertising in Japan to develop better, a class of search advertising; second banner (banners), and text links ads. But at this stage in China's Internet traffic costs more expensive, if you add a lot of banner and text link advertising, will greatly increase the user fees, this model is clearly not feasible at this stage. Founded in 2004, declared a monthly 3G portal has been very substantial advertising revenue. 3G is a portal to provide information on the phone-based wireless Internet company. In fact, the 3G mobile Internet portal called Portal, has been using the "dual core" strategy - "Portal + client software." Information from the 3G portal, advertising revenue accounts for the 70% of its total income. Forms of advertising on the phone from a single chain of text and pictures, color banner, user interaction, a gradual transition to higher technology, more diverse and mobile video streaming ad placement. The charger of  cell phone jammer  should be protected well for safety.
As the largest mobile browser company, UCWEB has not really commercialized. Advertising is the revenue model to explore one of UCWEB, UCWEB has now done some preparatory work, such as the establishment of billboards, advertising design and system development of communication and advertisers. According to statistics, in 2007 Japan's wireless Internet advertising market reached $ 574 million, the United States is 2.78 billion U.S. dollars. From market research firm iResearch iResearch predicts that by 2010 China's wireless advertising market as a whole will reach 3.0 billion. But compared to the hundreds of billions of Internet advertising market, or a small number. Mobile Internet advertising model used by many companies as the most common pattern, but in addition to forms of advertising to be excavated, the education of users and advertisers still need time. Wireless advertising market still need to produce two or three years, not only to cultivate users, advertisers have to cultivate. As 10 years ago, people can not predict there will be Google's keyword advertising, wireless advertising their own unique forms of advertising industry also need to explore. Who can tap into mobile Internet features head, who will be able to win the race. Different adapters should be matched for different  cell phone jammer .

However, TCL reported a Alcatel cell phone overseas sales of TCL Mobile Communication business from the "shock" state in the wake of one of the main driving force of its own-brand sales of TCL cell phones in the country accounted for only 10% of all sales . In this case, TCL-branded handsets to completely recover, not that they want to return to the heyday of 2003, even back to the first three domestic cell phone market share is very difficult, and TCL-branded handsets can not be revived once, It has the potential to become a great Alcatel OEM factory.
May 24, 1844. Morse's telegraph sent from Washington to Baltimore, the first telegram of human history, "how God created a miracle." June 2, 1875, when Bell experiments, sulfuric acid accidentally spilled his legs. Pain of his colleagues in another room shouted, "live, come help me." And the words passed through experiments in the cell phone calls in another room of live special ears, as human beings transmitted by telecell phone first sentence.  cell phone jammer can be quickly turned on.
In 1831, the British Faraday discovered electromagnetic induction, Maxwell used mathematical formulas to further Faraday, who described the research results, and to promote the theory of electromagnetic induction to the space. And 60 years Hou Hezi in the experiment confirmed the existence of electromagnetic waves. The discovery of electromagnetic waves, a "cable telecommunications" to "radio communication" turning point, has become a point of origin of the entire mobile communications. As one scientist put it "Mobile is stepping on the shoulders of the telegraph and telecell phone was born, with no previous efforts, wireless communications out of the question." One day in April 1973, a man standing on the streets of New York, took out a large brick about two wireless cell phones and start calling. 
The so-called standby time means: no card in the case, after a full charge, 24 hours a day, until the cell phone turns itself off, which during the time spent. In general, the standby time by the impact of the following situations: First, the network causes; Second, call the situation; Third, the battery life.

CMOS inverter in the case of capacitive load, it's opening time and closing time are equal, this is because the nature of the circuit with complementary symmetry. The figure indicates that when the vI = 0V when, TN deadline, TP conduction from VDD through the TP to the charging of load capacitance CL. As the CMOS inverter, the two values of gm are designed to be larger, the smaller its resistance, the charging circuit time constant smaller. Similarly, also analyzes the CL capacitor discharge process. CMOS inverter, the average transmission delay time is about 10ns.  cell phone jammer intelligent management system can perform function of safety and protection.
The figure is 2 input CMOS NAND gate, which consists of two series of N-channel enhancement type MOS tube and two parallel P-channel enhancement mode MOS. Each input connected to an N-channel and a P-channel MOS gate control. When the input A, B as long as there is a low, will make the NMOS connected to it, closing, and it is connected PMOS transistor, the output is high; only when A, B are all high-power Usually, only the two series NMOS transistors are turned on, the two parallel PMOS transistors are off, the output is low. When the input A, B as long as there is a high, will make its turn connected to the NMOS, PMOS transistor connected to it, closing the output is low; only when A, B are all low Usually, two parallel NMOS transistors are off, the two series PMOS transistors are conducting, the output is high. Overview of  cell phone jammer  intelligent system will be introduced in details.
Compare CMOS NAND and NOR gates we can see the work of the NAND gate is another series of tubes, the output voltage with the increase of the number of tubes; or non-doors on the contrary, the working tube parallel to each other, the output voltage will not have significant impact. Thus used more or door. The figure above shows the basic BiCMOS inverter circuit, for clarity, MOSFET symbol M denotes BJT with T said. T1 and T2 constitute a push-pull output stage. And Mp, MN, M1, M2 and the input stage composed of a basic CMOS inverter is very similar. VI same input signal acting on the gate of MP and MN. When vI high voltage conduction and MP MN deadline; and when vI is low voltage, the situation is the opposite, Mp conduction, MN deadline. When the output terminal of similar BiCMOS gate, the output stage can provide enough current to charge a capacitive load. Similarly, the charged capacitive load can quickly discharge through T2. After the delay time reaches,  cell phone jammer  will be automatically shut off.

CMOS TTL logic gate circuit came in after the second widely used to develop digital integrated device, from the development trend, due to manufacturing process improvements, CMOS circuit performance may be beyond the TTL to become the dominant logic devices. Operating speed of CMOS circuits can be compared with the TTL, and its power consumption and anti-jamming capability is far superior to the TTL. In addition, almost all of the ultra-large-scale memory devices, and PLD devices are manufactured using CMOS Arts, and lower cost. Early production of CMOS gates for the 4000 series, followed by the development of 4000B series. CMO current TTL-compatible devices such as 74HCT series TTL devices can be used interchangeably with. The following discussion first CMOS inverter, and then introduce other CMO logic gates.  cell phone jammer can prevent prisoners from remote fraud.
First, consider two extreme cases: when vI is logic 0, the corresponding voltage of approximately 0V; and when vI is logic 1, the corresponding voltage is approximately VDD. Assumed in both cases N-channel tube TN P-channel tube for the working tube pipe TP as loads. However, because the circuit is a complementary symmetry, this assumption can be arbitrary, the opposite situation will lead to the same result. The following diagram analysis of the time when vI = VDD work. The output characteristics of the TN iD-vDS (vGSN = VDD) (Note vDSN = vO), the superposition of a load line, which is the load pipe TP in vSGP = 0V when the output characteristics of iD-vSD. As vSGP <VT (VTN = | VTP | = VT), the load curve is almost a horizontal line coincident with the horizontal axis. Intersection of two curves that the operating point. Obviously, when the output voltage vOL ≈ 0V (typically <10mV, the current through two close to zero.  cell phone jammer intelligent management system can effectively solve the above problems.
It can be seen, the basic CMOS inverter is similar to an ideal logic unit, the output voltage is close to zero or + VDD, while the power is almost zero. The figure below shows the transmission characteristics of CMOS inverter diagram. Figure VDD = 10V, VTN = | VTP | = VT =
2V. As VDD> (VTN + | VTP |), so when VDD-| VTP |> vI> VTN when, TN and TP two shoot-through. Taking into account the complementary symmetrical circuit is a device to another device as it will drain load. Should also be noted that the device in the active region (saturation region) showed constant features, one of two devices can be used as a high resistance load.

 cell phone jammer can prevent prisoners from making confession in collusion through the illegal communication equipment. As the production process all the different manufacturers, the market is divided into winding type lithium polymer (Sony, Toshiba, as the representative), laminated (TCL, ATL representative) two different structures, but adapted to the specifications of demand for mobile phones mostly in the 4mm thickness or less. Compared with the liquid, due to the use of a thinner polymer packaging aluminum than steel, aluminum and thinner, and different production methods with liquid lithium, the thinner the better production of polymers, in theory, can produce the following 0.5mm thickness of the battery. Liquid lithium on the contrary, the thicker the better production, less than 4mm thickness of the battery is difficult to produce, even if produced, significantly less capacity polymer lithium battery, did not cost advantages. Thus, the battery is thinner, lower polymer production costs, higher production costs of liquid. However, the specifications of the thick liquid lithium supply chain mature, mature technology, high efficiency, high yield, has a strong manufacturing cost advantage. Then, the electromagnetic radiation on the human body mechanism is like? According to common sense, the human body is a conductor, we can absorb electromagnetic energy. The role of the electromagnetic field, the orientation of the body's molecular arrangement occurs in the molecular arrangement of the magnetic field during the collision energy consumed is transformed into internal energy, causing thermal effects. Electromagnetic field strength is larger, the thermal effect is more obvious; the higher the frequency of electromagnetic vibration, thermal effects, the more obvious. Scientific experiments have shown that electromagnetic radiation pollution on the health hazards are mainly two aspects - the role of induced thermal effects and non-pyrogenic. Thermal effect is caused by electromagnetic waves penetrate the surface of the organism, the body directly to the internal organization of the "heat" (the same as the microwave heating of food), that the role of high-frequency electromagnetic waves, the material will change the temperature, high-frequency electromagnetic waves caused by heat will have an impact on the role of organisms, which cause serious harm to humans, leading to breast cancer, impotence, miscarriage, fetal malformation and other diseases. Is the nonthermal effects of electromagnetic waves on human autonomic nervous system damage, resulting in heart palpitations, hair loss, bradycardia, hypotension and women's menstrual disorders and other diseases. Now that you understand the principles and hazards of electromagnetic radiation, how to do that in life preventive measures? China Interior Decoration Association Indoor Environment Test Center experts to draw attention to the following: For the indoor environment in office equipment, home appliances and mobile phones caused electromagnetic radiation hazards, people should take the following protective measures.

It is very important to test shielding radius of  cell phone jammer .Phase detector referred to as PD, PH, or PHD (PhaseDetector). A phase comparator, which changes the phase of VCO oscillating signal is transformed into voltage changes, the phase detector output is a pulsating DC signal, the pulse DC signal low-pass filter (LPF) to filter out high frequency components after control the VCO circuit. Phase detector is a phase comparator, its input reference signal generated by the VCO phase comparison signal input, two output reflects the phase error signal error voltage. Phase detector is varied, with numbers, but also simulated. Such as dual-port phase detector, PFD, etc.  cell phone jammer  can work as long as the antenna is collectively connected.
When using digital phase detector, because of its dual-port output output: In connection with the loop filter on a problem. Usually added in between a double-ended input single-ended output, and can phase detector output phase error signals correctly reflected in the circuit, this circuit is known as the charge pump or the pump circuit. Motorola's GSM mobile phone, its transmitter frequency synthesizer basically uses the pump circuit. In the frequency synthesizer, in order to make accurate phase comparison, the phase detector is working in a low state. In the mobile phone circuit, the phase detector is usually integrated with the divider is a dedicated chip, the chip is often referred to as PLL (phase locked loop), or integrated in a complex chip (the chip that contains a variety of function of the circuit). This kind of cell phone jammer  has its own characteristics
Selling on the internet is also a kind of sales channels for  cell phone jammer . Phone frequency synthesis loop and more loop frequency synthesizer using a different divider different: the receiver first local oscillator (RXVCO, UHFVCO, RFVCO) signal with the channel change, and the frequency synthesizer in the loop divider is a programmable divider, the divider ratio is controlled by the data signal frequency synthesizer (SYNDAT \ SYNCLK, SYNSTR). Two oscillator VCO, also known as the IF VCO (1FVCO, VHFVCO), the signal is fixed, IF VCO frequency synthesis loop in the divider ratio is fixed. Divider output signal to the phase detector, and the reference clock signal for phase comparison.  cell phone jammer  has the various sales channels and selling modes.
When the VCO is in normal working condition, VCO output a fixed frequency. If some external factors such as voltage, temperature can cause the VCO frequency is increased, the frequency output signal is f2 / N n higher than the reference signal, the phase detector to detect the changes, the output voltage decreases, the varactor both ends of the reverse bias decreases.
