客户对其公司的无线网络产生如下疑问:

公司成品仓所使用的刷枪为刷枪头和座机通过无线连接,座机通过双绞线连结到网络。

怀疑所用的无线频率与其办公无线网络使用的频率一样,而产生干扰

分析如下:查看了他们使用的无线刷枪的型号如下:

品牌:DATALOGIC Model no: OM-3010 433MHz

无线刷枪使用频率为:433.92 MHz, 910 MHz

而AP使用频率:2.400-2.483GHz(B/G/N) 5.150-5.350GHz 5.725-5.850GHz(A/N)

可以看出无线刷枪用和频率与公司无线AP用频率不会产生干扰问题。

以下为网上的这个品牌的无线刷枪别的型号用的无线频率为433MHz 和 910MHz
