What’s Amazon Sidewalk?

On broad terms, Amazon sidewalk is a three-layer encrypted wifi-network extender that improves wi-fi range and connectivity beyond your front door. It uses the same 900 MHz spectrum, used on Long-range devices like radios and digital pagers (emergency services) for decades. The Sidewalk creates a long-range, low energy network in places where the wi-fi and Bluetooth cannot otherwise reach.

What’s the confusion surrounding Amazon Sidewalk?

How safe is the Amazon Sidewalk?

“You’d be sharing a portion of your network bandwidth, but as a crowdsourced community benefit, the entire neighborhood can benefit from this feature,”

is Amazon’s point.
Amazon promises that your shared sidewalk network’s bandwidth would be limited to 80 kbps and capped at 500 MB per month. That bandwidth is about 10 minutes of high definition video streaming. You can turn it on or off as required. But what if you use up your data limit of 500 MB? Amazon has yet to clarify.
- Third-party applications and devices that share the sidewalk network must adhere to the three-layer encryption standards and strict contingency checks in place or drop off.
- A session ID gets generated when a sidewalk connection happens, and those IDs refresh every 15 minutes. The session IDs flush out from the database after 30 minutes of disconnection. Other routing information the sidewalk network server uses to move packets to and from the devices are cleared every 24 hours.
- The network has different levels to deal with unauthorized or rogue devices. One is the Sidewalk Gateway (GW) packet inspection: a received packet by the GW has to pass CRC and Sidewalk format checks, re-authenticating a Sidewalk endpoint(device) and blocklisting an endpoint(a sidewalk enabled device) if lost or stolen.

Can law enforcement agencies use any data Amazon picks?

Due to the least data retention and triple encryption policies on Amazon Sidewalk, the scope and the use of collected data collected is almost useless it assures.

Stay or opt-out of the Amazon echo sidewalk feature?

Amazon’s Sidewalk network is similar to the widely popular Xfinity wi-fi network. Xfinity uses the forced opt-in feature enabling its customers to get seamless connectivity across an entire city or wherever there is the Xfinity network. However, Amazon is clear and transparent about it, providing an open option to turn it off. No one except Amazon is recommending you to try it. You are the better judge, you know.
