18. What is iBeacon?

19. From welcoming people as they arrive at a sporting
event to providing information about a nearby
museum exhibit, iBeacon opens a new world of
possibilities for location awareness, and countless
opportunities for interactivity between iOS devices
and iBeacon hardware.

34. Smart meters can send real-time
information about energy
consumption directly to
homeowners, helping them conserve
energy and save on their utility bills
Smart home devices can help
homeowners save money and
use less energy. Rising natural gas,
heating oil, and electricity costs have
people more concerned with
consumption.
