Mounting Considerations
3.1.1
Positioning the Device
Install the WirelessHART gateway first, before installing other WirelessHART devices. This
way you can check for proper operation of new devices as they are installed. Please refer
to the gateway manual for further information.
Guidelines for Planning a WirelessHART Network
•
A line-of-sight between communication partners always is desirable. If a line-of-sight is
not possible, the obstacles should not be massive and the partners should be more to
the edge of an obstacle to allow the wave to bend around it.
•
Consider moving objects that could affect the device's antenna range.
•
Install wireless devices at leat 1 m above the ground or the floor.
•
Make sure that the device's antenna is aligned vertically for best results.
•
Make sure that a minimum of 2 other WirelessHART devices are well within the antenna
range of the device. For more information on the antenna characteristics please refer to
the following section.
•
Do not position WirelessHART devices directly below or above each other. They would
be outside each other's antenna range.
•
Install WirelessHART devices at least 1 m away from each other.
•
Antennas must be at least 6 cm away from any wall or any metallic material running
parallel to it.
•
Position the device as far away as possible from metal surfaces or walls containing
metal. There should be as little metal close to the device as possible.
•
Do not position other 2.4 GHz devices like cordless phone bases or WLAN routers near
WirelessHART devices. Keep in mind other wireless networks using the same
frequency spectrum (WLAN, Bluetooth, etc.). Wireless technologies used in an
industrial environment must be able to coexist without disrupting each other. If multiple
networks operate in one facility, a frequency management should be applied as part of
administration.
