exist simultaneously:
1. The distance between interfering devices (including wireless devices at the
frequency of 2.4GHz such as cellular communication devices, microwave ovens,
intercoms, cordless phones and electro-surgical units, excluding Wi-Fi) and the
monitor is greater than 20 cm.
2. Co-channel interference (CCI) on the Wi-Fi network should be no greater than
-85dBm.
3. Adjacent–channel interference (ACI) on the Wi-Fi network should be no greater
than -50dBm.
