如何加密无线蓝牙网络并保护数据

分类：设计开发下载：0 浏览：546 时间：2017-08-19

 蓝牙是一个由IEEE 802.15定义的无线网络。为了减少频率的冲突，蓝牙使用2.4MHz的波段进行操作。一个蓝牙连接的吞吐量则视该设备生产商所部署的版本而定。最大的数据传输率大约在1Mbps到3Mbps之间。而实际使用中的数据传输速率一般肯定会低于这个极限数字。

Abstract∗: Bluetooth is a personal wireless communication technology and is being applied in many scenarios. Current existing MAC (Medium Access Control) scheduling scheme only provides best-effort service for all master-slave connections. It is very challenging to provide QoS (Quality of Service) support for different connections due to the feature of Master Driven TDD (Time Division Duplex). This paper addresses the issue of how to enhance QoS support in a Bluetooth piconet. We propose an MAC scheduling algorithm which can provide different QoS for different connections based on priorities. Considering the feature of Master Driven TDD, we define token counters to estimate traffic of real-time slaves. To increase bandwidth utilization, a backoff mechanism is then presented for best-effort slaves to decrease the frequency of polling idle slaves. Simulation results demonstrate that our scheme achieves better performance over the existing schemes. Keywords: Bluetooth, Piconet, Master, Slave, QoS,MAC, Scheduling

国外大牛制作的射频计算表格，涉及线缆、传输等10多种计算表。只是英文的，使用起来稍为不顺，原想翻译中文的，但作者加了很多修改限制，而且好多数据是引用隐藏表格的，改后出错较多，也出于尊重作者还是直接提供给大家吧。 Attenuators Bandpass Filters Cascaded Components Coils / Inductors Delta-Wye (Resistors) Directional Couplers Doppler Shift Highpass Filters Lowpass Filters Mixer Frequency Conversion Near / Far Field Noise Figure↔Temp Path Loss, 1-Way Path Loss, 2-Way Propagation Time Radar Blind Speed Radar Horizon / Line of Sight Rectangular Cavity Skin Depth Smith Chart VSWR↔RL↔Gamma Voltage Divider Voltages & Power - Vrms, Vavg, Vpk
