wireless bridge in crane

[pema]

hey,

for an offshore windsubtation we are looking to us "C9115AXE-?" as a wireless bridge in a crane(1 meter distance between 2points).

1)Can somebody confirm that this will work if the antenna isn't aligned. the 2 devices will be mounted inside of the pedestal of the crane . When the crane is rotating there will be a position when the 2 devices are 45° out of side at 1meter distance?

2) can somebody confirm that the last letter is pointing to the countrie and because it will be used in france we need to use E?

thanks in advance for your feedback.

best  regards 

peter

I don't think folks here can give you an answer to a very difficult question.  Many will say test it out and see if it works.  The one thing you need to note also is the ap model.  Any access points that will be mounted outside, should be rated as an outdoor access point.  Also with the devices moving, you would need to have an omni directional ap with or without an external antenna and that would have to be mounted properly to give you the east west coverage.  I just don't know how well this would work, since there is a lot of metal, rf noise, etc.  Again, its something you would need to test and or reach out to folks whom have done similar setups in your line of work.

You can use below tool to check what AP part number to order based on the geo location where the AP will be installed.

If the distance is 1meter you may consider running a cable directly to the AP using an outdoor rated flexible cable wrap. Choosing the correct antenna must be done only after a site survey, especially when Mesh is required you need to check whether there is any specific coverage pattern required to achieve quality backhaul between RAP to MAP. I would suggest you that call upon a qualified wireless engineer to do a site survey along with a RF study and provide his outputs, if not you can test it yourself with 2 mesh supported omni aps and placing it in the original location. If you are testing, please make sure that you gather RF data, as this is mandatory to tune the RRM.

If the APs are exposed to the elements than that model is not suitable.

When you say bridge, are you expecting to connect clients directly to the back of one or both APs?

To advise if it will work - well given the distance is only 1m the question is more is line of sight blocked as the crane rotates? If so then it will depend on the material blocking line of sights properties as it could block the signal.
