CC1352R: TI 15.4 and mioty: Standards or proprietary ?

Part Number: CC1352R
Other Parts Discussed in Thread: MIOTY

Hey community,

I'm currently working on a thesis where I have to build a prototype for a Low-Power-Wide-Area-Network. I chose one of you MCU from the SimpleLink Portfolio since it supports TI 15.4 and mioty-Stack. For the writing of the thesis, I need some background information regarding those Stacks, just to know if I understood everything right. In the documentation, it says, that the stacks are eighter based on IEEE 802.15.4 (for TI15.4) or based on an ETSI-Standard (ETSI TS 103 357 for mioty).

So my first question is, in which sense they are based on the standard? From my understanding: mioty and TI15.4 Stack are compliant with the PHY and MAC layers of the respective Standards. So mioty and TI15.4 are implementations of the Standards, right?  But should I rather categorize them now as standard or proprietary protocols? 

My second question relates to the compatibility with other devices, which are based on the same standards. If I would build my own IEEE or ETSI compliant device, or buy one of a different vendor, does this mean that the devices can communicate with each other with ease? Is there any kind of certification? 

Thanks in advance, 

With kind regards

Thomas

    Hi Thomas, 

    1. Starting with mioty; if you read the specification there is no mention of mioty at all. That's because the technology in itself is based on the standard and the mioty stack is an implementation of the PHY and MAC layers specified under the TS-UNB family in the standard. When it comes to the TI15.4 stack; the stack is an implementation of the standard. I would categorize them as standard protocols as they are based on a standard, unlike proprietary protocols. 

    2. If you base it on a standard, you should be able to communicate with other devices. Just think about standard protocols that we use on a daily basis that are well established and have well-defined certification processes like Bluetooth Low Energy (BLE) or Wi-Fi. Different devices work well together in these standard-based implementations with different vendors, and as a consumer, you usually don't know which chip you are using. 

    Thanks,

    Hey Elin,

    Thanks for your answer,

    I still have some problems understanding everything. When I have a look on this page https://www.ti.com/tool/SIMPLELINK-CC13X0-SDK , it tells me that I have flexible PHY options (802.15.4g, Long-range mode, and synchronous mode).

    Now is the question: Is the Long-range-mode within the TI15.4-Stack also IEEE compliant or is this PHY layer proprietary? 

    Thanks,

    Thomas

    Hi Thomas, 

    Only the PHYs that are named "IEEE" is IEEE compliant. So no, the long-range mode for the TI15.4 stack is not IEEE compliant. 

    Thanks,
    Elin
