IEEE BPL group moves ahead on provisions
The working group is developing a new standard, IEEE P1901, "Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications." When completed, the project will present a standard for high speed (>100 Mbps at the physical layer) communication devices via alternating current electric power lines, so-called Broadband over Power Line (BPL) devices.
Technical Subgroup 2 (TSG2), which is dedicated to FFT and Wavelet MAC/PHY, presented thirteen revised chapters of the draft Standard on MAC/PHY layers and security.
Technical Subgroup 4 (TSG4), which is dedicated to coexistence, presented a draft annex describing the Inter-System Protocol (ISP) that enables various BPL devices and systems to share communication resources (frequency/time) when installed in a network with common electrical wiring. ISP will allow P1901-compliant devices and ITU-T G.hn-compliant devices to co-exist.
The protocol provides configurable frequency division for Access and time division for in-home with a granularity compatible with the Quality of Service (QoS) requirements of the most demanding audio and video applications.
The Working Group approved TSG2's revisions by an 83% majority, and unanimously approved TSG4's ISP annex.
The technical subgroups continue to hold weekly teleconferences as they further develop the first official draft of the P1901 standard. TSG2 also held a face-to-face meeting in Fukuoka, Japan.
The Working Group will next meet 21-24 July in Tokyo, Japan. For more information, contact the Working Group chair, Jean-Philippe Faure, at jean-philippe.faure@progilon.com or visit the website at http://grouper.ieee.org/groups/1901/Meeting_Information.html.

Quebec's electricity ambitions reopen old wounds in Newfoundland and Labrador
OTTAWA - As Quebec prepares to ramp up electricity production to meet its ambitious economic goals, the government is trying to extend a power deal that has caused decades of resentment in Newfoundland and Labrador.
Around 15 per cent of Quebec's electricity comes from the Churchill Falls dam in Labrador, through a deal set to expire in 2041 that is widely seen as unfair. Quebec Premier François Legault not only wants to extend the agreement, he wants another dam on the Churchill River to help make his province what he has called a "world leader for the green economy."
But renewing that…
