第六章叙述了基于x - 10的收发模块的软件总体结构第七章对语音识别在智能家居系统中的应用做了探讨。 - The millimeter has the largest frequency band and the highest velocity of communication , but it has the highest cost and technical defaults : multi - path effect , reflect and scatter caused by cloud , smoke , water - dropping , the buildings , the grounds and its shape , the interference caus ed by the thunder , the complexity of device , difficult maintenance , and so on . now the band of the leakage coaxial line is up to 3ghz , leakage coaxial line has some advantages : good adaptability to cloud , smoke , water - dropping , the buildings , the grounds and its shapes , good steady field , it has some technical defaults : lower resolution for location and measuring velocity , the more complex of its sending - receiving relay devices , weak anti - interference , the strict demand for the hole size in the line , the cleaner work environment and the higher cost
毫米波具有最大的带宽和最高的通信速率，但也有最高的成本要求和较难克服的技术问题，即传播的多径效应，降水、云雾、地形、地貌、建筑物等的反射散射，打雷时的严重干扰，设备复杂，维护困难等等；泄漏同轴电缆的带宽目前已做到3ghz ，具有对地形地貌建筑物的适应性强，场强稳定，但它的定位测速精度低，它的收发中继设备较复杂，抗干扰能力低，电缆上的开槽有着严格的尺寸要求，工作环境要求清洁，成本较高；传统无线感应技术具有结构简单，成本低廉，维护方便，定位精度较高的优点，但是，它没有抗干扰能力。
