Connection technology: The access network technology is one of the core parts of the modern telecommunication network system, which has the function of connecting local end users and end users. The wire network structure is mainly composed of UNI (user network interface) and SNI (business node interface). The core network is the link connecting user network interface and business node interface. Access network’s main function is to realize the user and the terminal equipment effective communication and information connection, compared with the optical fiber communication technology and bluetooth technology, access network technology does not have the reuse and cross connection.
Bluetooth technology: With the increasing intelligence of mobile phones, bluetooth technology has gradually entered people’s life. Bluetooth is arguably the latest communication technology in all communications technologies. Currently, mobile phones, laptops, wireless headphones and many other peripherals have bluetooth capabilities. It can be said that the promotion of bluetooth technology greatly simplifies the communication between the terminal devices. Bluetooth technology can achieve communication between wireless devices and the Internet, and the advantages of bluetooth technology to another big reflected in the exchange of information users in the use of bluetooth technology in the process of don’t need to pay fees.
