The aluminium textured outer shell of cell phone jammer

Not exactly, the increase of transmit power and receiver sensitivity to be increased (noise reduction coefficient) match; because the WiFi network is a two-way communication, power increases to a certain extent, the receiver sensitivity as a short board, not to improve communication effectiveness . Only communicate with each other two terminals are installed amplifiers when transmitting power higher the better. This technology of cell phone jammer avoids the recession of blocking distance.Like two people are needed to improve long-range loudspeaker volume must be the same. Why every answer two questions a few walls, the signal decreased a lot? Why every a few walls, the signal weakened a lot? A wall of 10-30cm thick brick wall on the 2.4GHz signal attenuation about 10-20dB, the signal of the floor of the block has more than 30dB attenuation, recommended that the antenna be installed in the location of a small obstacle. Why sometimes the signal will be worse?  Why sometimes the signal will be worse? 2.4G ISM band is a very busy band, Bluetooth, wireless camera, Baby Monitor, and microwave ovens all use this frequency band. Recommended amplifier antenna away from the location of these wireless devices. Work can also be switched router channels to try, as far as possible away from noise sources.The aluminium textured outer shell of cell phone jammer is excellent in thermal diffusivity. Amplifier does not shine red light? Shielded cable is not connected, or the card - there is no communication between the router there is no communication between routers.  shielded cable is not connected or no communication between the router card. Users to install their own antennas to pay attention to what issues? Note that the cable between the amplifier and the antenna length should not exceed 50cm, amplifiers and routing / length of cable between the card should not exceed 2m. 1m long shielded cable for signal attenuation of about 1.8dB, so the cable as short as possible. Slow flashing red light, but can not communicate?  Slow flashing red light, but can not communicate?

Shenzhen Jinli Spectrum Information Technology Co., Ltd. was established beginning with the development of proprietary products as the goal of information security, information security and to participate in building the Great Wall of China's unremitting efforts to continuously develop new technologies and new products.People selected and put the high-performance patch component to use in cell phone jammer. Company products include network security network security isolation card, network hubs, network switches, isolation gateway, mobile phone signal jammers, biometric fingerprint systems. New product design ideas, performance, stability, and has become China's leading information security products, the majority of users. Jinli spectrum is the early development of production networks and other network security separation card physically isolated products business, the most complete product line of professional manufacturers. Network security separation card number in the country over 20 provinces (municipalities) the official number of units used, the network physical isolation over many years of professional product development, production and sales experience.High-performance integrated circuit has been used in this cell phone jammer. Have an adherence to the "stable and reliable, real security," the spirit of professional technical team, perfect quality assurance system based isolation card, a brief description of J630 is our third generation of isolation card, with a smart chip on the card boot conventional isolation and network selection network switching technology for breakthrough improvement, an increase of switching to save interface functions, stable performance, easy to use and quick.
