Universal Powerline Association Broadband Powerline

The Universal Powerline Association announced at its annual meeting that it was backing the standardization effort based on the specs developed by Open PLC European Alliance, which were demonstrated in the European, Asian and U.S. markets last year.

The organization that was formed last year maintains that a worldwide PLC specification will assure service providers and customers that PLC will be compatible with equipment and content.

The group will also continue working on the Digital Home Specification that will provide seamless interfaces between in-home PLC (power line communications) wiring and cable, DSL and PLC broadband services.

Motorola’s BPL solution receives UL approval

Motorola’s Powerline LV modem this week received approval from Underwriters Laboratories (UL), meaning the vendor giant can begin shipping its broadband over power line (BPL) solution in the next month, company officials said.
UL approval also will let Motorola continue its testing with ARRL, the national association for the amateur radio community, said Dick Illman, a member the advanced wireless team in Motorola special markets division of engineering.
ARRL has been vocal in its criticism of many BPL systems that generate interference-causing emissions from broadband signals being transmitted over medium-voltage power lines. Motorola’s Powerline LV solution avoids this problem by using a Canopy wireless architecture to transmit the broadband signal to the transformer server an area, from which only low-voltage wires are used.

Although Motorola halted its tests with ARRL while seeking UL approval, tests conducted in the fall with ARRL were “perfect—there was no interference” to the BPL system or ham operations, Illman said.
In addition to removing medium-voltage lines from the interference equation, Powerline LV also utilizes notching—a practice used successfully by BPL vendor Current Technologies—to prevent transmissions on frequencies that could cause problems,” said Mary Ashe, business development manager for Motorola.
