Wireless planning
1.1
Power up sequence
The Emerson Wireless Smart Antenna and wireless I/O should be installed
and functioning properly before the power modules are installed in any
wireless field devices. Wireless field devices should also be powered up in
order of proximity from the antenna beginning with the closest. This will
result in a simpler and faster network installation.
1.2
Antenna location
The antenna should be mounted in a location that allows convenient access
to the host system network (wireless I/O) as well as the wireless field device
network.
