Oppedahl used microwave antennas to connect his nearby law office's network, which has a fast-access T1 line, to his home and the broadband box.

Just wait and see how many people do this when they learn they can get 50+ Mbps service via a wireless LAN at distances up to 30 miles (line of sight) and 5 miles (non line of sight). The standard (802.16) was just agreed upon, and equipment is starting to roll out. The only problem with wireless connections is the same as satellite service: Heavy rains and lightning can cause loss of signal.
