Overview
To plan and install FDAPs in a wireless network, it is essential understand the tasks
involved in it.
4.2
Prerequisites for installation
Network planning, RF site survey, FDAP placement, and analysing power requirements
are the prerequisites for FDAP installation. These tasks must be completed before
installing the FDAPs in the wireless network.
Network site planning must be completed to understand how a wireless network
can be built and supported for your application using OneWireless components.
These components consist of wireless device manager, FDAP, wireless field
instruments, and Multinode.
RF site survey must be completed by a qualified professional. The RF survey is
essential for building wireless network architecture. Perform the required site survey
and it should include the following tasks:
RF spectrum analysis must be conducted on the 2.40-2.49GHz band and 5.7-5.9
GHz band (if available to be used) to detect any potential RF interference. Strong
interference sources must be addressed (removed, avoided or minimized) before
the installation. Note that some frequencies may not be available for use in some
locations and countries.
A point-to-point 2-node mesh must be staged in various locations to measure the
RF propagation ability in the site. Received Signal Strength Indicator (RSSI) can
serve as an indicator of the RF environment. TCP/IP throughput testing and
UDP/IP throughput and packet drop rate testing must be conducted in all selected
locations to measure the quality of the signal strength in the site.
Site survey must be conducted after the factory system starts operating so that
maximum possible interference can be measured and addressed.
FDAP placement must be determined after the completion of the network planning
and RF survey activities.
Power requirements for network must be identified. Wired cable runs that provide
DC power to the FDAP must be determined.
Ethernet cable runs must be determined for FDAP and/or any other wired nodes in
the network.
