Sophie Charara, Wired:

Amazon’s new Sidewalk protocol and Apple’s experiments with ultra-wideband signal a new battleground that gets Amazon out of the house and Apple inside it

Apple is strong outside the house, weakest inside. The U1 Wideband chip hopes to give Apple very precise location information inside your house.

Amazon’s problem is the opposite. They have great reach inside the house, via Echo devices, but without a phone of their own, they depend on Android and iPhone to go where you are outside the house.

One core point:

For Amazon, in fact, that work has already begun as Sidewalk originally came out of the Ring team’s ambition to extend its connected security devices out into gardens.

There are already efforts by Amazon to share Ring doorbell footage with police departments to help fight crime. Clearly, privacy is a major issue here.

Interesting to watch these opposing solution sets unfold.
