Conduct a Site Survey

Performing a Site Survey before installing the WSN is a necessary procedure to
ensure reliable communication. The following description demonstrates the standard
process of Site Survey.
4.4.1

Before Going Onsite

1. Ask the customer for the maps and collect the information in previous chapter
the more the merrier.
2. Check with the customer for the possible position to install the coordinator.
3. Setup all modules
 Prepare the following items:
– ADAM-2520Z *1
– ADAM-2510Z *8, it depends on the area of site, 8 router can organize two 5-
hop network
– ADAM-2051PZ *1
– 2 AA batteries for the above modules
 Set all modules in same PAN ID and RF Channel. The RF Channel suggests to
be set to channel 15 or 20 to avoid the interference of WLAN.
 Set all modules' data cycle to 5 second.
 Set all modules as individual ID address.
 Install batteries for all modules.
 Switch all modules to normal mode and use utility to check all modules are
work.
 Switch all modules to initial mode and remove the batteries.
4.4.2

Onsite Survey

1. Setup Coordinator
 When arriving the site, power up ADAM-2520Z with batteries and switch it to
normal mode.
 Install ADAM-2520Z at the place that can be seen from most of the place or cor-
ner to ensure the signal can be easier to be accessed.
 If possible, do not install on the concrete wall, heavy column, or girder.
 The antenna should be vertical to the plane that going to install other modules.
2. Add Router
 Install batteries to one of the ADAM-2051PZ, and switch it to normal mode.
 Press the button of ADAM-2051PZ one time to check the link quality
 Walk away from coordinator and keep checking the LQI until only one LED level
is on.
 Add one router with batteries and work in normal mode at that position
 Check the LQI of router 5 times to make sure a least one LED level is on.
 Check the ADAM-2051PZ has full LED level at the same place, if only one LED
level is on, switch it to initial mode and then back to normal mode to re-register
the routing.
 Walk away from the new added router and use the same way to add next router
until the position of end-devices that will install can access the network.
