 ====== Gateway Node Hardware ======
+Requirements for the gateway node hardware:
+  * Run from wall power
+  * Persistent state
+  * Discover network link to the Internet
+  * Internet connectivity via WiFi or cellular (through external modules if needed)
+  * Receive system configuration data from the Internet and self configure (zero touch from fresh powerup)
+  * I/O sufficient to allow for double duty as a data collection node
+  * Linux OS to allow flexibility in feature set
+  * Local storage sufficient to buffer data collection in the event of link outages
