  1. Each reader operates in a particular frequency channel of the authorised 2. 45 ghz ism band

    每一臺感應讀卡機都必須在不同的頻道下運作，不能有任何兩臺感應讀卡機使用相同頻道。
  2. The zigbee performance of co - channel anti - interference is investigated. the coexistence problem of zigbee with some interferences in the 2. 4ghz ism ( industry, science, medicine ) frequency band is analyzed. by analyzing zigbee mechanism of anti - interference, such as channel algorithm, and by considering the condition of wi - fi, bluetooth, the following conclusion is reached : the proper choice of channel, larger frequency offset and a proper distance from a interfering source are the three effective strategies for further improving coexistence performance of zigbee

    3 .對zigbee技術本身的抗同頻干擾性能進行了研究，分析了在2 . 4ghz頻段zigbee和主要干擾源的共存問題，通過分析zigbee的通道演算法等抗干擾機制並結合wi - fi 、藍牙等技術的特點，得出結論:正確選擇通道、增大頻偏以及和干擾源保持一定距離是保證共存的三個主要措施。
