什么叫蓝牙
蓝牙是一种近距离的无线传输应用技术，在 10 —100 米范围内，把专用的半导体 装入机器中，无须借助电缆就可连接计算机、打印机、数字相机、电视机、手机、微 波炉等，并能同时进行数据和语音传输。是英语 blue tooth 的直译。下面是小编为您 收集整理的什么叫蓝牙，供大家参考 !
什么叫蓝牙
What is Bluetooth?
Bluetooth is a universal radio interface in the frequency band that enables portable electronic devices to connect and communicate wirelessly via short-range, ad hoc networks. Each unit can simultaneously communicate with up to sever other units per piconet. Moreover, each unit can simultaneously belong to several piconets.
What is Bluetooth Technology?
Bluetooth technology which apart from Ericsson, has gained the support of Nokia, IBM, Toshiba, Intel and many other manufacturers.
Eliminates the need for wires, cables and connectors for and between cordless or mobile phones, modems, headsets, PDAs, Computers, printers, projectors, local area networks, and so on, and paves the way for new and completely different devices and Characteristics —1Ms/s symbol rate exploits maximum available channel bandwidth.
Fast frequency hopping avoids interference
Adaptive output power minimizes interference
Short data packets maximize capacity during interference
Fast acknowledge allows low coding overhead for links
CVSD(Continuous Variable Slope Delta Modulation)voice coding enables operation at high bit- erro
