Have an Echo device? Amazon may help itself to your Wi-Fi

NEW YORK — Do you own an Amazon smart device? If so, the odds are good that the company is already sharing your internet connection with your neighbors unless you’ve specifically told it not to. On Tuesday, the company launched a program that forces users of many Echo smart speakers and Rings security cameras to automatically share a small portion of their home wireless bandwidth with neighbors. The only way to stop it is to turn it off yourself.

Amazon says the Amazon Sidewalk program is a way to make sure lights, smart locks, and other gadgets outside the home and out of reach of a Wi-Fi connection stay working. But some experts warn that the technology is so new that privacy and security risks remain unclear. And almost no one seems happy that Amazon forced consumers into Amazon Sidewalk — or that many people may not know they can opt-out of it.


Amazon says it sent emails to customers last month and that Sidewalk was coming in November. The company says you’ll also get a notification when you set up gadgets that work with Sidewalk.


Once you know about it, opting out of Sidewalk is relatively straightforward, if not exactly simple. Echo users can go into the Alexa app, tap “More” in the lower right-hand corner, then tap “Settings,” then “Account Settings,” where they’ll find a section for Amazon Sidewalk and a button to disable it. Goo to “Control Center” in the Ring app and tap “Sidewalk.”


The idea behind Sidewalk is to integrate residential wireless connections into a “mesh network” that can extend coverage to areas home Wi-Fi can’t reach. Amazon’s Echo and Ring devices band together to create this network by grabbing a slice of bandwidth from each cooperative home network. That can extend the range of devices designed to work with Sidewalk so they’ll stay connected even when away from your home network.

One example of such a device is Tile, a tracking device placed on keys or a dog’s collar. If your dog goes missing in a neighborhood where Sidewalk works, it might turn up quickly via Tile. Other products with Sidewalk include smart locks controlled by phone and wearable devices that can track people with dementia who may wander. Amazon expects additional devices, including outdoor lights and motion detectors, wto work with Sidewalk


Amazon is tapping into various radio technologies, including LoRa, for its long-range. It is better known for industrial and business applications such as keeping track of cattle roaming through pasturelands. “The goal here is not to create coverage for a single home,” said Marc Pegulu of chipmaker Semtech, which is partnering with Amazon on the technology. “It’s kind of a shared network, a community shared network.” Among other things, devices connected to the shared network can supposedly search for the best signal in a way that can preserve their battery life.

Thomas Clausen, a computer science professor at France’s École Polytechnique, says that the network Amazon is creating could be good if it’s open andaccessiblel because it would make it easier and cheaper to use internet-connected devices and sensors and spark innovations. “But of course, when a behemoth like Amazon, or Apple or Google or Microsoft, create a platform, they also can end up controlling the platform, which can stifle innovation,” he says.


Hackers could potentially infiltrate home networks via Sidewalk, said Eric Null, a digital rights group Access Now policy manager. If that happens, Null said hackers could observe everything you do, take over your devices or access your files to steal information. “It’s only a matter of time before someone’s network gets hacked and data gets breached,” said Null. William Tong, Connecticut’s attorney general, warned consumers this week that the program was “uncharted territory” and that people should opt-out of Sidewalk unless they are sure their privacy and security will be protected. “Wireless networks are already notoriously vulnerable to hacks and breaches,” Tong said. “Families need better information and more time before giving away a portion of their bandwidth to this new system.”


When asked about privacy and security concerns, an Amazon spokesman said he couldn’t respond to “hypothetical situations.” The company didn’t respond to a request to make an executive available for an interview but noted that data that flows through its network has three-layers of encryption meant to keep hackers from seeing it. Samir Jain, policy directory at the Center for Democracy and Technology, said Amazon’s efforts to encrypt data was a good step. But Jain said that it’s hard to identify security vulnerabilities until a new technology is deployed in the real world.


Echo devices that share network bandwidth via Sidewalk include the third generation and newer versions of the Echo, Echo Dot, Echo Dot for Kids, and the Echo Dot with Clock. The Echo Show 5, 8, 10; the second generation of the Echo Show; Echo Spot; Echo Plus; Echo Studio; Echo Input; Echo Flex. Sidewalk-enabled Ring devices include the Ring Floodlight Cam, Ring Spotlight Cam Wired, and Ring Spotlight Cam Mount.


Amazon has explained Sidewalk in the context of consumer devices such as cameras and speakers. But it could also one day integrate the technology into its core business: delivering goods. For example, the company could embed tiny internet-connected devices into cardboard packages to help track them, said Clausen of École Polytechnique. “Having the integration of alarm systems, presence detection of whether or not people are there, will potentially allow Amazon to create more efficient delivery schedules and fewer re-deliveries,” he says. That could be one application Amazon is thinking about, he added.
