Interference caused by other radio systems

Check frequency ranges

  • WLAN networks on adjacent or the same channels
  • Microwave ovens

WLAN

If the IEEE 802.15.4 channel used by the KM6551-0000 and the frequency range of a neighboring WLAN network overlap, this can lead to disruptions in the KM6551-0000 communication.

Select an IEEE 802.15.4 channel for the KM6551-0000 that uses the gaps between neighboring WLAN networks as shown in the figure below.

Even if the maximum possible three non-overlapping WLAN channels are used adjacently, four IEEE 802.15.4 channels remain that the KM6551-0000 can use without interference.

Utilizing gaps between adjacent WLAN networks
  1. Three non-overlapping WLAN networks in the WLAN channels permitted in North America (IEEE 802.11b)
  2. Three non-overlapping WLAN networks in the WLAN channels permitted in Europe (IEEE 802.11b)
  3. Placement of EEE802.15.4 channels (2400 MHz PHY) in the gaps between WLAN networks

Microwave ovens

Since microwave ovens typically operate at a frequency of 2.455 GHz, neighboring poorly screened ovens can interfere with the transmission between the KM6551-0000.

In this case, remove the interfering devices or use only well-screened microwave ovens in the direct vicinity of the KM6551-0000.
