Is this what they are doing? Seems unlikely that you would transmit so much overhead when the data rate is so low, unless you needed to overcome a lot of noise.

It’s about the numbers, there’s trade-offs for each specific application. I would encourage people to do the math and see if their design makes sense for their goals.
- AlotOfReading 5y agoThere's virtually no benefit to dedicating so much of your message to checksums with any remotely efficient algorithm. More practically, any CRC >= 32 bits is probably overkill and any CRC > 64 bits is definitely overkill until you get up into gargantuan message sizes.
- Isamu 5y agoAgreed, for this application (texting) a simple approach is probably best. You have to look at the particulars of your domain, it’s not one size fits all.
