Seriously? When it rains? Why is that an issue? And how about fiber-optic, it could be affected by rain too, couldn't it? A local company here in Oregon spent a bunch of money to put a fiber-optic link under the ground out to a foreman's office at a timber company. Unfortunately, they put this link underneath the path where the big lumber trucks drive in and out, causing lots of mud and guck and standing water. The fiber-optic link had all sorts of problems! So then they tried wireless. Guess what? A wireless signal doesn't go through tall trucks stacked with logs very well. Last I heard, the final solution was a copper link in a sealed conduit. It exceeds the supposed 100 meter limitation, (which is why they had originally thought fiber), but it works fine and was cheapter than replacing the water-logged fiber equipment. Just a fun story from the Pacific Northwest that I thought you would all enjoy. :-) And guess what, it hasn't rained here for almost 2 weeks! Hooray.
