1900 1990MHz is also contained in the working frequency of cell phone jammer

 1900~1990MHz is also contained in the working frequency of cell phone jammer .
Brand and customer base better. Earlier from the Chinese network is one of the manufacturers to enter online, through continuous development, has formed a good brand and user base. As of the end of March 2009, page views from the Chinese network has reached 300 million times / day. In addition, from the Chinese networks literature as a grand site, as Shanda comprehensive line of wireless entertainment business, one in human resources, product integration operations (such as the original literature into online games, etc.) also has a large advantage . Chinese online (www.ChineseAll.com) was established in 2000 at Tsinghua University, is one of Chinas Internet publishing pioneer, leading to the most legitimate digital content broadcaster. At present, the Chinese online products or services related to educational institutions, government agencies, public consumption, in various market development in a leading position.
Chinese online product content, copyright and other aspects of operations and customer base are more advantages, mainly in the following points: rich, extensive resources: Chinese online digital rights in China earlier one operating company, has accumulated a rich content resources, in addition to the Internet with the original literature, but also a broad range of primary and secondary education for users, courseware and other content resources, and have literature classes, art classes, childrens class, economics and management, integrated classes, education classes, lifestyle, tools and other literary works. This type of cell phone jammer can work as long as the antenna is collectively connected and the power supply is switched on.
Resources are more extensive content partners: Chinese online now with publishers, writers, original site, the book established the upper range of content partnerships, at present, with more than 400 publishers, more than 8,000 well-known writer, mo re than 20,000 Web authors to cooperate. On the Internet, wireless Internet has a wealth of content operations experience, reading the users structure, needs, content management and control have a deep understanding. Operating experience and extensive collaboration with government departments: Currently, the Chinese already have Monternet online, mobile own business experience of cooperation, the Chinese telecom operators have a wealth of management experience working system.

The antenna determines the shielding range of cellular phone jammer

The antenna determines the shielding range of cellular phone jammer. 
Should implement prevention unit is responsible, focused, ensuring safety "approach, in accordance with the principle of" who is in charge, who is responsible for the development of safe production responsibility system. Security work into the performance appraisal. A month to conduct a safety check, make a record, identify problems and timely rectification. Check the results and linked to the income of employees, through the specification and inspection to ensure the implementation of various rules and regulations. Pre-job of the salesperson, business training, security, confidentiality, and legal education, and pass the examination can be employed. To develop a cell phone store receipts, cash-carrying on the way the anti-robbery prevention and emergency response plans, and the familiar, once the incidence, rapid and effective processing solutions. The direction of cell phone jammer is decided by the antenna.
Security facility configuration, capital safety, electrical safety, fire safety management with reference to the business hall of Jiangsu Mobile Communication Co., Ltd. safety regulations "file execution. The information security manager responsible for the confidentiality of sales information: information security education on a regular basis, and stores the information security implementation of the supervision and inspection. For all types of business documents, internal company documents, work information, technical data and statistical analysis data, non-license led by the higher authorities, all employees shall not be privately available to any individual or entity shall not be privately copied, disk copy, or network transmission other ways out of the workplace. Systems Engineering in the case of stores people personnel changes, job transfers and permission to adjust the situation. The antenna and battery of cell phone jammer are the built in type.
The store manager shall promptly submit an application to the higher authorities, with the completion of work the application, close, permission to adjust the work in accordance with the requirements of the higher authorities. Business accepted members in their daily work involved in customers personal data, cost information, call list information must be kept strictly confidential and shall not be divulged. Customer data to strict management, the timely entry of the BOSS system. The raw data shall be properly kept on time and returned to the company. Place of business must be set within the computer power-on password may not be equipped with floppy drive must be disconnected from the network after work. Business computer, the timely replacement of the BOSS job number passwords should be based on the requirements of the higher authorities.

TV Remote Control Jammer

This circuit confuses the infra-red receiver in a TV. It produces a constant signal that interferes with the signal from a remote control and prevents the TV detecting a channel-change or any other command. This allows you to watch your own program without anyone changing the channel !!    The circuit is adjusted to produce a 38kHz signal. The IR diode is called an Infra-red transmitting Diode or IR emitter diode to distinguish it from a receiving diode, called an IR receiver or IR receiving diode. (A Photo diode is a receiving diode).


Circuit Project: TV REMOTE CONTROL JAMMER Circuit

There are so many IR emitters that we cannot put a generic number on the circuit to represent the type of diode. Some types include: CY85G, LD271, CQY37N (45¢), INF3850, INF3880, INF3940 (30¢). The current through the IR LED is limited to 100mA by the inclusion of the two 1N4148 diodes, as these form a constant-current arrangement when combined with the transistor and 5R6 resistor.

Simple Mobile Phone Jammer Circuit Diagram

Description
                 Circuit displaying a cell phone jammer.Here i have used a fm transistor for making this circuit.Mobile cellphones are working in 450  MHz  frequency .Here the transmitter generate virtually equal to 450 MHz  frequency there for the mobile telephone does not determine the original signal however the sign range may be very week so this circuit working in most effective 100 m range .This circuit working in handiest 450 Mhz .Do now not supply extra than three V
