Why RF Power?
• Wire-free Operation
– Untethered placement and mobility
– Operates anywhere in range of a suitable RF power source
– One-to-many charging
• Reliable
– Power source is controlled/deterministic
– Available on demand
– Minimal effects from weather / time-of-day
• End product differentiation
– Sealable / waterproof
– Zero maintenance
