LAN chipset talks over power line

LAN chipset offers power-line communications A two-chip set version of
the company's AN192 power-line carrier LAN module is available. The
product employs spread-spectrum techniques, and incorporates an
adaptive/wideband approach and noise-immune networking protocols
specifically developed for handling worst-case power-line noise and
attenuation. The system transmits raw data at 135 kbits/s, with forward
error correction and automatic repeat request, providing an effective
throughput of 19.2 kbits/s with an established reliability of a
10-9 error rate. The product can address over 64,000 nodes and
transmits over ac, dc, 110 to over 480 V, 50 or 60 Hz, and multi- or
single-phase power lines at distances up to 4 km. ($25 ea/large
