Tips on overcoming RF barriers
•
When first creating the network in the environment where
the loggers will be deployed, form a new network on the
Receiver. There may be local interference on the 2.4 GHz
free bandwidth. The ZigBee protocol, when forming a new
network, selects the least noisy channel (out of 16
available channels). Within this channel the units can
change RF slots (by hopping) but cannot move to other
channels while running. By running on a channel on a
network created in another environment e.g. in the office,
this channel may become noisy and therefore
transmission range may be less than expected.
•
When placing units in an indoor or outdoor environment,
bear in mind that walls, furniture, metal objects, etc. limit
the RF coverage thereby reducing the range of the units.
•
Add Repeaters (DNR800 or DNR900) in range of end
units and parent unit to enhance RF coverage and
improve robustness of network. Have as many alternative
transmission routes as possible in order to eliminate
single points of failure.
•
When placing Repeater ensure it is not on the limit of its
range to the end unit or parent unit (Repeater or
Receiver), to avoid periods of unavailability due to
changing RF conditions.
•
Add Short Range Repeaters (DNL910, DNL920 or PA
models) to overcome RF interference nearby to the
loggers.
•
The higher the Receiver is positioned the better reception
quality it will obtain.
2.8.3. Showing the Network Path
By going to Network > Show Network Paths in the DataNet
main menu, the software will show the actual path that the
