Hardware design of double frequency wireless sensor network node

The wireless sensor network node is first analyzed,a hardware structure design of the double frequency wireless sensor network node based on 2.4GHz and 433MHz is proposed.The wireless sensor node based on this design idea can be used to build wireless sensor network by multiple communication protocol and network architecture.It can communicate with each other either in a short dis-tance and low power consumption at 2.4GHz based on ZigBee communication protocol or in a long distance based on 433MHz by wireless power amplifier.It is also a powerful experimental platform for the research in this domain.
