Corridor Invents 216Mbps Powerline
Posted: 22nd Sep, 2003 By: MarkJ
Corridor Systems has invented a so-called 'breakthrough' technology called PowerCorridor, which is designed for very high-speed communications over medium-voltage powerlines (Powerline Broadband PLC):
CORRIDOR SYSTEMS ANNOUNCES BREAKTHROUGH TECHNOLOGY FOR BROADBAND OVER POWERLINES (BPL)
Corridor Systems today announced results of the latest testing of its PowerCorridortm system for very high-speed communications over medium-voltage powerlines. In what is believed to be the highest communications speeds ever achieved over a real medium-voltage powerline grid, the company demonstrated end-to-end capacity of 216 Mbps four times faster than has been claimed with any previous technology.
It is exciting to see this new entry into the BPL market. The BPL industry will benefit significantly from higher-capacity networks such as Corridor Systems is claiming. High performance and low-cost will allow BPL to compete with Cable and DSL by offering a superior product. This is good timing given that bandwidth-intensive applications such as streaming audo and video and telephony are becoming popular.-- David Shpigler, President, The Shpigler Group
Unique approach and use of low-cost WiFi chipsets takes BPL to new level
A prototype PowerCorridortm system was deployed over a section of 12kV grid operated by Pacific Gas & Electric, one of the largest combination natural gas and electric utilities in the United States, serving over 13 Million people. The test configuration linked two computers located at either end of the ¼ mile segment transporting Ethernet/IP end-to-end. Working with PG&E staff, the Corridor Systems team conducted a number of tests with results confirming several aspects of this unique approach including:
* 216Mbps raw capacity with simultaneous, bi-directional, and symmetrical, end-to-end delivery
* Very low overall latency of less than 500 microseconds, 20-100 times lower than other solutions, making the system ideal for time-critical applications such as telephony and real-time video.
* Multiple independent channels each operating bi-directionally, allowing segmentation of bandwidth to support advanced service-level agreements.
* 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, thereby reducing upstream network operating costs.
* Viability of leveraging low-cost 802.11 chipsets for powerline communications to achieve costs per home passed significantly lower than competing BPL solutions.
* Potential to use future wideband technologies to deliver significantly higher capacities.
PowerCorridortm leverages 802.11 for low-cost chip-sets, simplified end-user access
PowerCorridortm is based on the companys patent-pending E-Linetm technology capable of delivering many hundreds of Megabits of capacity over a single conductor medium-voltage powerline. Under development for the past 2.5 years, the unique physical-layer approach enables very low cost implementation and robust operation while achieving unparalleled performance. PowerCorridortm further reduces system costs by using mass-market 802.11 chip-sets in the core system components.
The PowerCorridortm system delivers end-user access wirelessly over 802.11b/g from any point along the electric grid. A Homeplug-compliant version for end-user access over the low-voltage lines is also in development.
Availability
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.
Its unclear whether the technology would be compatible with UK networks.
