I am trying to determine which is more expensive:
1) Adding additional battery capacity to enable the XBee3 to stay active
2) Allow the XBee3 to enter Power Saving Mode between network data updates.
My initial logic would have been to power-down to reduce battery load, but I am finding that entering and leaving Power Saving mode seems to incurr additional network bandwidth which utimately effects the long term cost of deployment.
I am having trouble determining how large this overhead is, because usage reporting (by AT&T at least) is not very granular, and seems to be dependant on the IOT device connection state. The usage-data updates seem to coincide with the device disconnecting from the network, so the "Staying connected" usage data is extremely delayed.
When specifically asked for details, AT&T support reply was to provide me with daily usage numbers and the suggestion: "related to any Device configuration queries please reach out to the device vendor". So here I am.
I would assume that anyone designing Cellular IOT services would need to know how usage is being accumulated and charged before deploying any significant number of units... Is there a best-practices guide/whitepaper for this anywhere or any is it all just shrouded in secrecy?
