Telcos have used a lot of wireless media - microwave links have been heavily used for long-distance networks long before the current low- cost equipment became available. Of course, they do the maths and know about leaving sufficient fade margins. Wire lines can also fail of course, but generally under different situations, so the two are often complementary. Much of the first spread-spectrum equipment to work in unlicensed spectrum came with the right connections to run E1/T1 over it. Dragging things back slightly more on-topic, wi(4) has proved very reliable; there has been some recent mention on soekris-tech (http://marc.theaimsgroup.com/?l=soekris-tech&m=114982978006733) about ral(4) stopping working after a while, though it's not yet clear whether it's related to soekris 48xx, or whether there's some interaction with sis(4), or whether it's something else.
