'Amazon Sidewalk' is a low-capacity, low-power-consumption, long-distance wireless network. With a network of linked devices such as Amazon Echo, security cameras, and loss prevention tags ' Tile Pro ', you can simplify reconnection even if the Wi-Fi connection is interrupted and extend the operating range.
Using the Tile Pro as an analogy, if a dog with a Tile Pro attached to its collar runs away while walking, the basic function will notify you with a sound if you are within the range where you can connect to your device via Bluetooth. In addition, when other Tile users pass nearby, their location will be notified. In addition to this, if you're connected to Amazon Sidewalk, you'll know when your dog walks through the Amazon Echo network in someone's home.
In other words, the materials show that security and privacy protection are well considered, as they are connected to other people's terminals. In fact, no voice points out that the encryption or other protection measures described in this document are vulnerable.

However, the news site Ars Technica has a history of being used for four years until it turns out that one of the wireless LAN encryption methods 'WEP' can be deciphered, and Bluetooth also has many defects. Pointing out the fact that they are still being used, he asks, 'Why do you think your own framework is superior when even the industry-standard technology is like this?'
The information that Amazon obtains from related equipment is very detailed, and it is clear that ``who visited this house'', ``what kind of things are going on indoors, and what kind of conversations are being exchanged'' On top of that, he's in control of the house keys and security system. Ars Technica argues that if the reach of such data extends not only to your own house but also to your neighbor's house and the street in front of your house, you need a corresponding degree of reliability. .
In addition, Amazon Sidewalk is not an `` opt-in '' method that the user needs to set by himself when using it, but an `` opt-out '' method that the user needs to change the settings by himself if he does not use it. Ars Technica points out that this is because Amazon understands that the only way to spread the service is to turn it on by default.
By the way, setting itself not to connect to Amazon Sidewalk is easy,
1: Open the 'Alexa' app
2: Open advanced settings
3: Open Account Settings
4: Open the 'Amazon Sidewalk' item
5: Turn off 'Amazon Sidewalk'
It is said that it is OK. Service coverage is US only at launch.
