CC1312R: Maximum data rate supported

Part Number: CC1312R
Other Parts Discussed in Thread: CC1352P, CC1200

Hi,

I am considering CC1312R for using it 6LoWPAN in subGHz band.

1. I am littile bit confused about the maximum datarate it can support in Sub-GHz using 6LowPAN. What is maximum datarate it can support for 6LowPAN

2. What is software stack availability for 6LoWPAN

3. Which Power amplifier is best suited for it (20dBm output power)

Thanks

    Hi Hijack,

    1. 6LoWPAN is based on IEEE 802.15.4 PHY, and for Sub-1 GHz supports different data rates. Our devices supports 50 kbps for IEEE 802.15.4g on Sub-1 GHz.
    2. Our devices only support for Sub-1 GHz 6LoWPAN with Contiki
    3. If you require 20 dBm PA then you must use one of the CC1352P devices.

    Hi Edvard,
    So again I have few more question
    1. So which device from the TI offers 1MBPS on 6Lopwan, and in Sub-GHz
    2. If there is no SOIC (MCU+transceiver) then do I need to go with separate MCU and transceiver.
    3. Which tranceiver offers atleast 1mbps data rate on IEEE 802.15.4 and can support 6 LoWPAN.
    4. What could be the possible solution for considering high data rate+6LowpAN +SubGHz band+Microcontroller

    Thanks

    As I know, 6LowPAN doesn’t support such high data rate.

    1) None. Maximum data rate on the IEEE 802.15.4 PHY is 250 kbps, so you will never get 1 Mbps with 6LoWPAN (at least if you want to be compliant).
    2) Not sure if I follow here. All of our CC13xx devices are MCU+transceiver.
    3) None, see point 1.
    4) We have 200 kbps for Sub-1 GHz which are IEEE 802.15.4g compliant. Any of the CC13xx devices supports this PHY.

    Thanks Edvard.
    So in CC1200 I can see that 1.25Mbps is mentioned as datarate. So what does its actual meaning.

    Also I have seen that on below link that datarate is 5000. What does it mean. For which protocol this datarate supports.

    Thanks

    Regarding 1.25 Mbps on CC1200 I'm not sure, but it is not referring to the IEEE 802.15.4g PHY.

    Regarding 4 Mbps on CC1312R it is referring to the High Speed Mode (HSM) PHY, which is a proprietary TI PHY specially created for our devices. HSM is not a compliant IEEE 802.15.4g PHY.

    6lowpan is loosely defined as running IPv6 over IEEE 802.15.4, and 15.4 defines a number of physical layers (modulation+data rate+freq bands etc). The radios (cc13xx, cc1200, etc) can often run in a number of modes, of which one or several of the 15.4 defined modes are included. They can often run in other modes too, but these are not part of the 15.4 standard, and as such are not strictly part of a 6lowpan stack.

    If you don't care about other implementations and possible interoperability, you can run any combination you'd like, including a PHY layer eg the TI HSM mode, that has higher data rate.

    Be aware that the data rate is correlated to practical limits of how far you can transmit between devices. This means that if you are striving to maximize transmission distance, the data rate seen in practice might be lower than you expect due to dropped packets (ie retransmissions) or increased hop count (a device may chose to send "over" an intermediate device).

    Hope this helps,
