Instructor: Mark Weinstein
Suppose you are in downtown Boise, Idaho, and someone calls your Virginia 703 number. Your device rings, hums or vibrates. How did it know where you were and how did the call and its information get routed to you? Welcome to the world of cell towers, two-way radios, intelligent switches, massive data bases, GPS, communication software, WiFi, data plans, and whatever tomorrow brings. Many people bonded to their smartphone have no idea how it works. We will see what makes this 21st century mind-bending innovation tick.
