如何在工业物联网中实现无线诊断
有许多不同的无牌频段的无线操作在世界各地，每个乐队有不同的影响收集诊断数据的工业物联网（物联网）。一些乐队如2.4 GHz有标准的协议如ZigBee、蓝牙和Wi-Fi，可以用来收集数据和有关工业设备和访问网络的诊断数据。其他1子频段，而潜在的低成本和较长的范围内，不提供这些功能。
The application requirements are also important. Industrial IoT applications for diagnostics require less data than streaming video or file transfers， and so there are many more options for the designer. The size and positioning of the network is also important. Higher frequency bands offer more channels and more bandwidth， hence can serve larger networks and drive more data throughput. Lower frequency radio waves propagate better than higher frequency and so achieve better range， especially inside buildings.
Each of these bands also have different optimizations and processing requirements. The higher performance requirements of the protocols in the 2.4 GHz band have a major influence on the design and power consumption of the wireless transceivers. However， continual evolution of the silicon design by companies such as Texas Instruments is constantly updating the technology， reducing cost and power with higher levels of integration of digital and analog components.
