	TECHNICAL PROGRAM – 108 papers, 3 workshops The theme for INTELEC 2002 is Reliable Energy: The Driving Force Behind Dependable Communications. It will be addressed in depth by both the keynote and the plenary speakers, who will explore factors currently affecting the reliability and availability of energy on the utility grid. Also addressed will be strategies that wireline, wireless, cable and broadband operators can deploy to meet increasing expectations of its customers for uninterrupted and dependable communications. Attending the Technical Program qualifies you to record Professional Development Hours, which, in many jurisdictions, are required as evidence of your maintenance of your continuing professional competency for engineering licensure. On request at the on-site conference registration desk, INTELEC will issue you a certificate to help you record your participation and tally your claim of 1 PDH for every hour of technical session attended.
