CEPCA Goals

1) Develop PLC coexistence standard• Oct. 6, 2005 Initial specification

approved• Q4–Q1 2006 Spec evaluation and field

trials• Q2 2006 Publish final specification

2) Promote coexistence worldwide• Participate in international standards• Recruit companies in every region

3) Encourage PLC deregulation in Japan

March 27, 2006

CEPCA Coexistence = Reliability

CEPCA specification promotes coexistence• Reduce Power Utility service calls• Minimize CE product returns• Non-partisan solution ensures wide adoption

No Returns

Why not just wait for a standard?

Standards take time• A CEPCA consensus accelerates standardization• Incremental solutions reduce risk while standards

develop

CEPCA strongly supports standards• CEPCA members submitting proposals to IEEE, ETSI,

PLC-J• Participation encourages coexistence• Rigorous review refines CEPCA proposals

Summary: CEPCA Goals are Unique

CEPCA members are PLC technology users• Need realistic, low-risk way to add features to products• Representing access, control, and AV markets• Users define what technology providers must do to make a

sale

CEPCA is technology-agnostic• Founders using five+ technologies• Impartial forum lets technologies coexist & compete

CEPCA is a global effort• Global companies Worldwide solution• Strong membership includes America, Europe, and Asia
