Broadband over Powerline (BPL) technology company Corridor Systems today announced the results of latest testing of its PowerCorridor system for broadband communication over medium-voltage powerlines.
The company said it demonstrated end-to-end bandwidth of 216 Mbps—four times faster than has been claimed with any previous technology—which it believes is the highest communication speed ever achieved over a real medium-voltage powerline grid.
PowerCorridor is based on the company's patent-pending E-Line technology capable of delivering hundreds of Megabits of bandwidth over single-conductor medium-voltage powerline. The technology has been in development for 2.5 years, and uses 802.11b/g wireless connections from any point along the electric grid to end-users. A Homeplug-compliant version for end-user access over the low-voltage lines is also in development.
Corridor Systems plans continued testing and trials of its system with other leading utility and service provider partners in the coming months. General availability of the PowerCorridor system is planned for Q2 2004.
The prototype PowerCorridor system was deployed over a section of 12kV grid operated by Pacific Gas & Electric.. The test configuration linked two computers located at either end of a quarter-mile segment, transporting Ethernet/IP end-to-end. The company said the tests confirmed numerous aspects of its approach including:
* 216Mbps raw bandwidth with simultaneous, bi-directional, and symmetrical end-to-end delivery
* overall latency of less than 500 microseconds
* Multiple independent channels each operating bi-directionally
* Use of microwave bands for very high information capacity powerline communications while avoiding interference issues of some other BPL approaches
* Very low emissions levels compliant with FCC Part 15
* Simple, rapid installation with no electrical characterization of grid required
* Performance capabilities that allow creating networks which span more than 5 miles
* Viability of leveraging low-cost 802.11 chipsets for powerline communications
