The horizontal suppression beam-width of cell phone jammer

The horizontal suppression beam-width of cell phone jammer is 150°.
Bluetooth car hands-free system allows the driver to dial directly through the speaker system, and its Bluetooth cell cell phonecan be placed anywhere in the car, so to keep their hands clenched the steering wheel, eyes close attention to road conditions. Even through a Bluetooth-enabled motorcycle helmet also stay connected. Bluetooth products shipped over 5 weeks of one million in the next few years, Bluetooth technology in mobile devices and automobiles implementation will continue to grow. Through all these mobile products, consumers will be able to more easily use the Bluetooth technology on the way to stay connected. cell phone jammer can be applied to the temple and theater. 
Only several specific, vulnerable Bluetooth-enabled mobile phones, old-fashioned bluesnarfing attacks. What mobile cell phonemanufacturers to take steps to solve these problems? Nokia and Sony Ericsson are vulnerable to bluesnarfing and bluebugging attack against the mobile cell phonehas developed a software upgrade. The two companies also made great efforts to ensure the new cell phones will not be affected by these attacks. About how users access to mobile cell phonesoftware upgrade is available for more information, please visit the Sony Ericsson and Nokia. Insert the power supply of the first detector of cell phone jammer intelligent system into the city electricity socket.
Auto safety researchers eavesdropping software is a software development tool that can be connected through a specific implementation of the Bluetooth car kit and send and receive audio. Personal use of this tool the user can not authorize the remote device, hidden in a remote connection to the car and communication, to send speakers to the remote device to receive audio and audio from a microphone. If there is no special equipment, personal laptop personal computer running the car in the eavesdropping tools, vehicles must be maintained at the target range of 10 meters. Security researchers aim to highlight a Bluetooth-enabled car kit to implement a variety of weaknesses, forcing manufacturers to ensure that the Bluetooth-enabled devices with higher security.
How to identify my car kit or car is vulnerable to eavesdropping software auto attack? To receive a car eavesdropping tool to access, car kits need to keep in pairing mode, with a standard fixed four digit PIN code, and not with the cell phoneconnection. If you always keep the cell phonepaired with the car kit, you can not connect unauthorized devices to the car kit. There are concerns about the individual user, if he has been in a car kit with a standard pairing mode and a fixed 4-digit PIN code (eg 0000 or 1234), should contact the manufacturer directly to find out more about the vulnerability of their equipment information, and access to suitable software upgrade car kit.
