Hi, I just promised to send some additional information about the power consumption graphs I was just showing.
The "idle" current draw (WiFi tethering on, phone on, cellular idle) in one of the measurement was about 138mA (in the figures I had this was the zero-line). When the cellular interface got active the current draw increased to about 323mA (i.e. in this measurement the cellular interface draws about 185mA, or accounts for 57% of handset's current total draw when active). In the three shown artificial scenarios (40s periodic messages) the average current drawn by gateway's cellular interface were: 1) 20s difference in packets: 87mA 2) 5s difference in packets: 64mA 3) 1s difference in packets: 37mA Obviously the achieved power savings range from virtually none to very significant, fully depending on the frequency of periodic messages nodes in a scenario are emitting and what is the power consumed by local area network interface. If the local area network would be low-power network (802.15.4, BT-LE), the relative power consumed by cellular interface would be significantly higher than in the case of this measurement where local network was WLAN. Best regards, Teemu
