> It should be a tradeoff of less battery consumption on device, and no need for large storage, at the expense of a lot more bandwidth?
Yes. I believe so.
> Would having to send all the raw samples consume more or less battery than just processing it and sending the result?
Good question. I don't know the answer to that. Maybe someone can chime in?
What would be interesting if you could send a "ping" signal to the tracker and it only start sending samples back then. After all most of the time you don't need to know where the cat is, only when it is "overdue" and the owner starts worrying.
One of the things I found initially surprising (but less so when I thought about it), was that when I switched from wired headphones to bluetooth, I got longer battery life from my phone. Apparently, there’s less energy involved in sending a radio signal than in driving a speaker.
Yes. I believe so.
