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 https://grouper.ieee.org/groups/1901/Meeting_Information.html.
