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 100 and

300m, depending on the terrain topology.

–

A GATEWAY hosts 80 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.

The GATEWAY is powered via Ethernet using the PoE technology (Power over Ethernet) based

on the 802.3af-2003 and 802.3af-2009 standards. This allows both data and power delivery over

category 5e or better cables. So ideally your site has an Ethernet network carrying cables

providing PoE.

If your site does not provide a connection insuring the standard PoE technology, then you

need to use a PoE injector that must be compliant with the 802.3af-2003 and 802.3af-2009

norm. This standard ensures interoperability between your power sourcing equipment and

the powered device GATEWAY.

The PoE connector stamped OUT goes to the GATEWAY.
