Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Y 4th Generation Intel® Core™ processors are based on Intel® microarchitecture formerly known as Haswell, manufactured on 22 nm process technology with 3D tri-gate transistors. This platform provides excellent CPU, graphics, media performance, flexibility, and enhanced security over the 3rd generation Intel® Core™ processors, making it ideal for a broad range of intelligent systems.
