Hello.
We are currently testing two systems, which are functiong well.
System 1 has 4 CR216X data loggers sending data wirelessly to a RF416 connected to a computer with LoggerNet.
System 2 is the same but with only 3 CR216X data loggers.
The longest distance between the RF416 and a CR216X is approx. 700 meters. (770 yards)
All the antennas are type 2,4 GHz OD6 Omni antennas.
The settings we have made are:
Hop Seq: 0
Channel: 0
Adress: 0
The problem is that I can not get a stable connection to one of the CR216X data loggers.
This CR216X is located approx. 4 meters (4,4 yards) from annother 2,4 Ghz antenna which is for a camera system. This antenna is directional and is sending in the oposite direction as our OD6 antenna.
When I switch off the power supply for this camera system, I immediatly get a connection to my CR216X with a good signal strengh.
How can I best solve this problem? Can I switch our system to another channel?
Or would it best best for me to use a directional antenna on the CR216X data loggers?
Any help would be highly appriciated.
Cheers,
LJ
Do you know what wavebands the camera is using? Often they are pretty broadband and difficult to work around with any other 2.4 GHz device. If it is not too wideband it should be possible to select non-clashing channels.
Changing to a directional antenna on the CR216X might help a bit, but most antenna like that still have significant sensitivity in the opposite direction (depending on the reflector design). Putting a cruder block in between might be a simpler solution as a starter, e.g. a sheet of metal!
Hello Andrew,
Thank you for your reply.
I do not know the wavebands that the camera is using, at this time. But I will look into that.
Another option I have is to move our antenna a bit further away. With the current installation I can move it a few meters more away from the other antenna. If the antennas were maybe 10 meters apart, instead of 4, would that make any difference?
Also this application is at open sea, which probably makes the communication even more sensitive. Then putting a physical block between the antennas is a bit impractical.
Cheers,
Any separation in distance will help and also moving the antennas to be at different heights. (Any antenna with gain, especially highly directional ones, will have much reduced sensitivity outside of the plane in which they are focussed.)
