LAUNCHXL-CC1352R1: CC1352R as a concentrator and more.

Part Number: LAUNCHXL-CC1352R1
Other Parts Discussed in Thread: CC1352R

Dear all TI Engineers and Experts,

I have compared many long range wireless technologies.  I plan to deploy many CC1352R as node MCU to control sensors.

Then, I will also use a separate CC1352R to collect all these nodes' sensor data within 10km radius.  I will accompany this CC1352R concentrator a LTE dialup modem to connect to internet back end server.

Now my question is:

  • Do I need another intermediate MCU to connect this CC1352R concentrator to the 3rd party LTE dialup modem?  If yes, can you recommend a TI MCU and its development board to me?

Yours faithfully,

Timmy  Upside down

    - First thought is that 10 km is a bit optimistic, please use https://www.ti.com/tool/RF-RANGE-ESTIMATOR to estimate the range with your setup.

    - It should not be required with an extra MCU. The CC1352R has SPI, UART etc which should enable you to communicate with most 3. party LTE modems.

    Hello Ter,

    Thanks for your opinion.

    I heard that TI CC1352R has a long range mode which works up to 100km.  Is it true?  How do I make this mode to work?

    Please check out the range estimator, playing with the different parameters makes it easier to undertand what is possible. We have tried to make the range estimator to give a range that is possible to achieve in real life with some margin. You can possible get 10 km range and longer with low datarate but that would require that the collector is placed very high above ground and that the place where you use the network has low background noise.

    Ter,

    Yes, I have downloaded the table, thanks.

    I think my CC1352R concentrator will collect all the nearby CC1352R sensor nodes readings, process and then send them as MQTT messages through a 3rd party LTE modem back to a server over internet.

    Can you recommend to me a Code Composer Studio example project which is the closest to my purpose?  Here on CCS, I see many of them but don't know which one to choose.

    Yours faithfully,
    Timmy

    We have examples on how to send data through a serial interface but nothing as specific as MQTT (to a LTE modem)

    I would assume that the LTE documentation covers how to use this and the data format?
