[ARRL-ODV:9623] Corridor Systems 5 GHz BPL

The following online article mentions putting 5 GHz on the power line to deliver ultra-fast BPL: http://www.telecomweb.com/broadband/feature.htm While it might be difficult to implement in practice, the principle is not as wacky as it may first sound. A low-loss single-conductor microwave transmission line, called "G-line" in honor of its inventor Goubau, was mentioned in ARRL publications 40 years ago. I don't know for certain that this is what Corridor Systems is doing, nor do I necessarily see the advantage of doing this instead of simply using 5 GHz wireless. But I thought it was worth passing along. Dave K1ZZ
