Bluetooth security mechanism is intended to provide the appropriate level of protection, if the user has a higher level of confidentiality requirements, you can use a valid transport layer and application layer security mechanisms.? cell phone jammer is palm sized.
Bluetooth devices should be interoperable, for some devices, compatible with modules and from the radio air interface, until the application layer protocol and object exchange format, interoperability must be achieved; on some devices (such as head-mounted devices, etc.) requirements are much more lenient. Bluetooth program?s goal is to ensure that any tag with a Bluetooth device can be interchangeable operations. Software interoperability begins with the link level protocol multiplexing, device and service discovery, and packet fragmentation and reassembly. Bluetooth devices must be able to recognize each other, and by installing the appropriate software to identify high-level functions to support each other. Interoperability requires the same application layer protocol stack. Different types of Bluetooth devices have different requirements for compatibility, users can not expect the head-mounted device containing the address book. Bluetooth compatibility means it has wireless compatibility, ability to send and receive voice and the ability to discover other Bluetooth devices, more features will have the mobile phone, handheld devices and laptop computers to complete.? cell phone jammer is easy to carry.
Bluetooth (BLUETOOTH), was launched in 1998 a new wireless transmission, replace the data cable is actually a short-range wireless communications technology, achieved through low-bandwidth radio point to point, or multipoint connection between the information exchange. This network model is also known as private space network (PAN, PersonalAreaNetwork), is more sophisticated micro-network or Bluetooth master / slave driver to build a mini web-based, each micro-network consists of eight active devices and 255 attachment structure, and several micro-link and form a network to expand network to easily and quickly to achieve the communication between the various types of equipment. It is the wireless transmission of voice and data open standards, is a low-cost, short-range wireless connectivity technology.? cell phone jammer is ecologically friendly.Chipset mainly refers to the Bluetooth headset Bluetooth chips used in the design of the composition. Bluetooth chip on the market today many manufacturers. Major telecommunications manufacturers have designed in accordance with Bluetooth standards have different chipsets. If the Bluetooth-enabled mobile phone with a Bluetooth headset with a Bluetooth headset must support two protocols: Headset profile (Headset) and HandsFree Profile (Hands-free). Slightly before the establishment of the network, all devices in the ready state. In this state, the device is not connected once every 1.28s monitor news, equipment, once awakened, in the pre-set frequency hopping on 32 monitoring information. The number of frequency hopping vary by region, but the 32 hopping frequencies used by most countries.
