Specialist Task Force 384:
Coexistence VDSL2 – PLC

Who we are:

Team Leader: Antonio Jiménez de Parga
Team Members: Philippe Gay
Nicolas Dangy-Caye

What we do:

The STF will analyze the data collected during the VDSL2 – PLC Plugtest performed in June 2009 in order to produce a theoretical model of the coupling between electrical wires and telephone wires. Additionally, the STF will elaborate a set of recommendations and algorithms to avoid or minimise the signal coupling from one medium to another.

The STF will produce a Final Report which for delivery to the PLT Group and three progress reports:

  • Progress report for Phase 1. Channel modelling and coupling.
  • Progress report for Phase 2. Simulations and selection of algorithms for coexistence.
  • Progress report for Phase 3. PLT implementation of coexistence algorithms.
  • DTR/PLT-0020: Final report on VDSL2 – PLC coexistence.

For more details, see our Terms of Reference

Why we do it:

The next generation of broadband access services is expected to use VDSL2. Since VDSL2 and PLC use the same frequency band, some telecom operators have raised concerns that there could be mutual interference between both systems.

This work is useful not only for current PLC technologies but also for future G.hn based systems.

The goal is to develop a set of recommendations and algorithms to avoid or minimize the interference.

Time plan for the work:

June 2009 Preparatory Meeting
