4.1 Overall methodology
Installing an HIKOB radio network requires a good topology analysis of your site to
maximize radio transmission quality by optimizing positions and numbers of HIKOB nodes
in the network. A preliminary study done with your vendor determines elements that will
constitute your HIKOB radio network acquisition.
Draw a site map: position your stationary sensors on parking places for WISECOW-P;
on the way where passing vehicles should be controlled for WISECOW-T; where road
temperature have to be measured for WISECOW-W; and so on with other sensors types.
Then you can determine the number of routers you need for your network following these
rules:
– The maximum distance between buried sensors and the GATEWAY is 30m.
– The maximum distance between a LION and a GATEWAY, varies between 50 and
150m, depending on the terrain topology.
– A GATEWAY hosts 100 elements in all, and 30 as direct children in the multi hop
radio network.
– The LION, the HIKOB router hosts 16 sensors or other routers.
For good radio transmission, both GATEWAY and LION need to be installed on
elevated spots, around 5m high. You will have better signal transmission with routers close
to sensors and far from other routers or GATEWAY.
Keep In mind that RF waves quality heavily rely on the environment they propagate
in. Identify the most distant sensors, and zones where you suspect waves will propagate
painfully, like having metal or concrete obstacles in the way.
The GATEWAY provides useful user information to appraise the radio signal quality
between elements of the HIKOB network. Refer to section Radio quality link in the
NETPULSE manual for that.
With a system based on a GATEGAY LITE, useful information to appraise the radio
signal quality between elements of the HIKOB network are available into the NETPULSE
APP product.
