Amazon Expands Data Monitoring
October 13, 2020
Here is an optimistic view of the future, at least for areas where residents can afford to purchase these gadgets. CNET reports, “Amazon Sidewalk Will Create Entire Smart Neighborhoods. Here’s What You Should Know.” Yes, Amazon’s vision of the smart home has grown to encompass the whole subdivision. Based on how many Echo devices are backward compatible with the new tech, the plan has been in the works for some time. But what, exactly, is this project about? Reporter Ry Crist writes:
“First announced in 2019, the effort is called Amazon Sidewalk, and it uses a small fraction of your home’s Wi-Fi bandwidth to pass wireless low-energy Bluetooth and 900MHz radio signals between compatible devices across far greater distances than Wi-Fi is capable of on its own — in some cases, as far as half a mile, Amazon says. You’ll share that bandwidth with your neighbors, creating a sort of network of networks that any Sidewalk-compatible device can take advantage of. Along with making sure things like outdoor smart lights and smart garage door openers stay connected when your Wi-Fi can’t quite reach them, that’ll help things like Tile trackers stay in touch if you drop your wallet while you’re out on a walk, or if your dog hops the fence. Maybe most noteworthy of all is that Amazon Sidewalk won’t require any new hardware, at least not for short-range benefits like easier device pairing. Instead, it’ll arrive as a free software update to the Echo speakers and Ring cameras people already have in their homes.”
To take advantage of those half-mile range 900MHz connections, though, one must have newer devices: a Ring Spotlight or Floodlight cam, the fourth generation Echo smart speaker, or Echo Show 10 smart display. (More will follow, of course.) These users will also contribute bandwidth to the cause, but Amazon was wise enough to provide an opt-out option. Not everyone’s community spirit will extend to their Wi-Fi connection, no matter how little bandwidth Sidewalk will use (which is very little, compared to streaming and other functions). Since the change will come in the form of a software update, anyone who wants to decline may have to be on the lookout for that update and find the appropriate checkbox.
Some users will have security concerns, and the company has worked to address them. The Sidewalk server only gets to see packets’ destination information, we’re told, but not any of the actual device data, which will travel under three layers of encryption. They promise to delete routing information every 24 hours. Here is the PDF of the company’s white paper addressing privacy and security for Sidewalk. Customers will have to trust Amazon to safeguard their data for Sidewalk to take off, it tells us. Considering how many have already incorporated the company’s digital potential spies into their homes, we think the project has a good chance at success.
