Project Plan• Integrate Polling with Existing Infrastructure
– Communication Team to research/implement– SCADA Team has on-hold– Renewable Energy Team commitment to fund
• Second Option: Erect Dedicated Polling System -- tie in to Infrastructure – Communications/SCADA to consider after First
Option failure• Satellite Communication is not an option
Internship Experience• Excellent Learning Experience Matched to
Academic Interest• Opportunity to work with Commercial,
Federal and Tribal Entities• Interdisciplinary Opportunity• Contribution to a Real-World Solution for
Tribes
Special Thanks!• Sandra Begay-Campbell• Deborah Tewa
