cell phone jammer is to shield the GSM frequency band
cell phone jammer is to shield the GSM frequency
band, CDMA frequency band and 3G frequency band at the same time.
And broadcasting 24 hours. Fourth, the development prospects of Chinas mobile TV and countermeasures of Chinas mobile TV prospects for the development and Countermeasures 4.1 bottlenecks in the
development of mobile TV to the diverse needs of the audience on the mobile terminal is gradually increasing, making the mobile TV market has shown signs of the trend gaining momentum, the future
can not Limited. Country in the process of development of mobile TV, in some respects, has achieved some success, but also suffered a number of bottlenecks, such as regulatory policy confusion,
lack of communication content, communication technology is lagging behind the lack of professional mobile TV professionals, the use of tariff The high technical standards are not uniform and other
bottlenecks. Regulatory policy confusion. But the area out of the shielding range will not be affected by cell phone jammer .
Management regulations in the telecommunications or radio and television and the management of the mobile TV business clearly defined, the Ministry of Industry and SARFT there mobile TV The
controversy led by whom. In order to capture this emerging mobile TV market high ground, handset manufacturers, telecom operators, radio and television operators have joined the field, the media to
be outdone involved. In accordance with the relevant provisions of the Administration of Radio, all those engaged in online audio and video programs play unit must apply to the Radio and Television
Information Network 09016475 "introduced by the end of 2000, the Telecommunications Ordinance expressly provides image transmission is also a telecommunications areas The former belongs to the
administrative provisions, while the latter is the national laws and regulations. cell phone jammer is developed and manufactured on the basis of the existing product.
The two cross-cutting policies and regulations so that the regulatory policies of the mobile TV 17 confusion. Chaotic regulatory policy also caused a conflict of interest between different
departments, can not reach a consistent understanding of the operating mode of the mobile TV standards, and not within the legal and institutional framework for effective coordination of
broadcasting and telecommunications, and rural development, therefore very make life difficult for the development of mobile TV to create a stable communication environment, hinder the development
process of mobile TV. Secondly, the chaotic regulatory policy to the mobile TV services to carry out the obstacles. For example, some wishing to launch mobile TV service company, to get the mobile
TV business license must apply to the different authorities. cell phone jammer cab be validly used in the prison, detention house, labor camp and so on.The design of cell phone jammer is totally

Safe Constant Current Source Circuit Diagram
In the Safe Constant Current Source Circuit Diagram shown, a CMOS op amp controls the current through a p-channel HEXFET power transistor to maintain a constant voltage across RL The current is given by: 1 ~ VREF/Rl. The advantages of this configuration are: (a) in the event of a component failure, the load current is limited by Rl; and (b) the overhead voltage needed by the op amp and the HEXFET is extremely low.
