4. Installation
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 HIKOB WISECOW-
P; on the way where passing vehicles should be controlled for HIKOB WISECOW-T; where road
temperature have to be measured for HIKOB 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 HIKOB GATEWAY is 30m.
–
The maximum distance between a HIKOB LION and a HIKOB GATEWAY, varies
between 100 and 300m, depending on the terrain topology.
–
A HIKOB GATEWAY hosts 80 elements in all, and 30 as direct children in the multi hop
radio network.
The HIKOB LION, the HIKOB router hosts 16 sensors or other routers.
–
For good radio transmission, both HIKOB GATEWAY and HIKOB 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 HIKOB 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 HIKOB 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 HIKOB
NETPULSE manual for that.
