Data over power lines

An article by IHT on the progress of BPL (Broadband over Power Lines), and new products coming to market. I still wait for the day…

Panasonic started selling its HD-PLC Ethernet adapters for power lines last month. A $200 starter kit provides two units, each about the size of two sticks of butter. One adapter is attached to a router with a short Ethernet cable and plugged into a nearby wall outlet. The second device is plugged into an outlet elsewhere in the house. When a computer is linked to it with an Ethernet cable, data is transmitted through the home’s electrical wiring at speeds of up to 190 megabits a second. Up to seven devices can run on the network.

Netgear, a leading maker of wireless networking gear, will be selling a similar system next month for $250. (Every additional module costs $130.) It moves data at a slightly faster rate.

Marantz says its ZR6001SP receiver will send music to special speakers in another room over power lines. The system, which includes both devices, will sell for about $1,200. Additional speaker units cost $300. The music listener controls the receiver and the players connected to it from a control pad on the speakers
