Wireless considerations
Power up sequence
The Smart Wireless Gateway (Gateway) should be installed and functioning
properly before power modules are installed in any wireless field devices. Wireless
field devices should also be powered up in order of proximity from the Smart
Wireless Gateway beginning with the closest. This will result in a simpler and
faster network installation.
Antenna position
The antenna should be positioned vertically, and be approximately 3-ft. (1 m)
from large structures or buildings to allow for clear communication to other
devices.
Mounting height
For optimal wireless coverage, the Gateway or remote antenna is ideally mounted
15- to 25-ft. (4,6 to 7,6 m) above ground or 6-ft. (2 m) above obstructions or
major infrastructure.
Gateway redundancy
If the wireless Gateway was ordered with redundancy (Gateway Redundancy code
RD), refer to Appendix D in the Smart Wireless Gateway Reference Manual
(document number 00809-0200-4420) for additional installation instructions.
