Design of Wireless Network Node in Building Based on Frequency Hopping Communication Technology

Taking the wireless information transmission in building as object,using frequency hopping communication technology,combining with pseudo-random sequence technology and synchronization technology,the frequency hopping wireless network node was designed and the function that information could be transmitted stably and synchronously in building was realized.The frequency hopping method and anti-interference principle were introduced,and the hardware and software design were introduced.The method largely resolved problems,such as the signals fast fading and mutlipath delay,and had good reliability.
