RTOS/LAUNCHXL-CC1310: cc1310 Maximum number of nodes(easylink,TI 15.4 stack)

There is new CC1352 has larger RAM/Flash so it should be able to support up to 200 nodes.

1.If the cc1310's RAM and flash are as large as cc1352, Is the cc1310 capable of communicating with 200 nodes?
(Is the size of flash and ram the only factor that allows communication with 200 nodes?)

2.If the cc1352 communicates with 200 nodes, is it connected via sub-1Ghz? Or is it connected via 2.4GhZ?

When you state that the datatransfer cycle is 10 seconds I assume that you mean that each sensor sends data every 10 seconds. What you also have to think about is if this is possible. You didn't state which LRM version you use but common for all of them is that they use a very long preamble/ sync pattern. To avoid collisions/ congestion on the air due to many sensors the total ontime pr cycle for all sensors must be set as low as possible. How low is dependent on where you put up your network, other noise on the air etc. This is something that has to be tested.

I have two questions.


  "You did not state which LRM version you use but it is common for them to use a very long preamble / sync pattern."

=> The long preamble is about the RF packet structure part in LRM. So is the sync patter talking about RF receive timeout?


"To avoid collisions / congestion on the air due to many sensors, the total on-time prc for all sensors must be set as low as possible."

=> I did not understand the meaning of the above. Could you explain it in a little more detail?

I saw the thread below.

TI-15.4 is a full stack and Easy link is called very fundamental TX / RX.

What exactly does it mean by a full stack? Can you explain the difference between TI-15.4 and Easy link in more detail?


thanks
