I created this flowchart to illustrate the flow of data between a private data network, radio and the Internet. Why is this important? Consider this scenario:
Power is out, the Internet is down and cell phones aren’t working. Let’s say all of Southern California communications are down (A likely scenario during a major earthquake). You need to send an email to an adjacent agency including a detailed list of medications and medical equipment that you need delivered to your area now. You know as well as any good emergency communicator that trying to do that over voice is not the efficient way to communicate lengthy detailed information, but you can’t reach any Winlink gateways outside your area. Luckily, you’re participating in the AREDN data network, so you can send an email!
