Anton, did you even read my post?

If you don't know what you are doing then you don't deserve to be a distributor in this space.

How are you going to isolate the access points?
What rating zones will you need to meet?
What existing arrestors are in place? (gas, fibre, etc)

In addition, what ranges are they expecting from the access points?
What physical environments are the signals going to be operating in? (steel etc)
What 2.4 ghz interference can be expected from other emitting industrial equipment.
What physical environment issues need to be considered condensation, salination, operating temps etc.
Will these wifi handsets be a workers only form of communication or is there a backup dead mans pager/radio alert systems (occupational health and safety issues etc)

There's a reason why intrinsic costs money and it's got a lot more to do with safety than will the satellite signal work well.

Cheers,
Dean
