Yes, if you’re worried about it using (from the article) 80kbps of your bandwidth.

Otherwise no.

Think you might be mistakenly mixed up device to cloud speed vs device to device speed.

I think it states 500mb cap for device to device comms. That's a decent pipe for comms.

To quote the whitepaper [1] itself:

The maximum bandwidth of a Sidewalk Bridge to the Sidewalk server is 80Kbps, which is about 1/40th of the bandwidth used to stream a typical high definition video. Today, total monthly data used by Sidewalk enabled- devices, per customer, is capped at 500MB, which is equivalent to streaming about 10 minutes of high definition video.

My reading is that there are two caps that both apply to the same, device-to-cloud data usage:

- 80 kbps instantaneously per bridge device (e.g. Echo)

- 500 MB per month "per customer" (not sure if this is different from per bridge)

This seems reasonably consistent. At 80kbps, 500 MB would take about 14 hours to transfer, which is much less than a month, but I think the expectation is that bridges rarely max out the 80kbps.
