Amazon Sidewalk is a new long-range wireless network

I will be happy to see LoRA got more attention and used more widely. You can build your own LoRA network across large area with zero monthly fee once it is up and running, and you pay monthly fee to NB-IoT just like your cellphone plan, which one you prefer? Not to mention LoRA is technically better.
I guess I would like to know the hardware setup involved in a large area to avoid any fees. Can you give a theoretical infrastructure requirement?
So, it is just an access point and then some clients, basically?
We have discounts for various groups including Women in Tech and Students, so just contact the organisers and we can sort out any support that you need.
First time hearing that, where did you get that?
Second, LoRaWAN uses an ALOHA medium access scheme, which also suffers from poor network spectral efficiency compared to basically every other medium access scheme out there. So these two things combined mean that a LoRaWAN network probably won't be able to handle much traffic.
Almost all of the media I see about LoRa and LoRaWAN talk about the great range, which is really good, but then gloss over the network performance. So in my opinion LoRa is a bit too hyped at the moment. I also think that when LoRa came out, it was the only PHY that bothered to go down to really low bit-rates, and then the range basically comes from the Shannonn-Hartley theorem. People think that LoRa gets its range from some fancy signal processing tricks or whatever, but I think it's just the fact that they bothered to drop the bit-rate very low. That's basically what SigFox is doing as well, but they're using a more typical narrowband PHY and so probably won't suffer from the same network capacity problems.
Fuck this "all in one ecosystem" mentality. :\

What profit would companies have made if they'd privatized TCP and the internet as we know it never was able to take off?
A world in which you build an extremely valuable network which benefits everyone, is a world where the profit itself is more valuable, the value of anything is higher.
IPX/SPX, right?
If I'm building something to give connectivity to dog tags, why not do something simpler?
I'm personally rooting for this to bomb badly.
I suspect the quickest way to find out if this is LoraWAN or Zigbee or Weightless will be to keep an eye on who switches to a Mongo/Redis style "commons clause" of "SSPL" license... ;-)
Just like Apple packaging up CPUs and memory chips. I think most people in tech having a hard time to understand that UX is everything. You can take the Athena example of AWS, even though it is just PrestoDB the difference of UX is enormous. A data scientist (end user) cannot download presto compile it, create a EC2 cluster with failover push it there, configure it, performance tune it and keep updating it but she/he can got to AWS console and pull up the Athena interface and type in a query. This is why "just packing" is very important and people are willing to pay for it.
(I do, though, have some sympathy for the problems companies/projects like Mongo and Redis have where Amazon makes all the money off their products without contributing to the development of them. )
No useful technical details yet to know much about it.
I am very confused by Amazon's radio protocols. Even though most of this has come through acquisitions, they are:
Eero - Thread (2.4GHz mesh IPv6, 802.15.4) Alexa - Zigbee (2.4GHz & optional 900MHz mesh, 802.15.4) Ring - Z-wave (sub-GHz mesh, proprietary)
Doesn't seem like a big issue for the IoT common case (switches, controls, alarms.)
Assuming that you have a border router (or similar persistent member of the network) who is in charge of disseminating your firmware over the mesh, you can either go with an algorithm that is unicast or multicast.
Unicast can be tricky because you don't really want different firmwares running on the same network (especially if the firmware includes a networking stack update). It also takes a long time, because you have to send X bytes N times.
Multicast can easily flood a network, even with rate limiting, because the amount of hops or rebroadcasts required can result in exponential growth in network activity.
Simply extending the amount of time it takes is problematic. What if a device restarts? What if it drops off the mesh?You are definitely correct in that it is solvable. It is not incredibly simple, though.
I doubt they will pay cert costs for other companies. Maybe they’ll provide a pre-certified package though.
I don't think it's a mesh. My first reading of this was the same as yours, but on a second read I think they've just set up a network of base stations, in the same way that something like LoraWAN works.
Without a GPS doesn't provide too much utility. With a GPS would probably need very frequent charging.
I mean, I get it, getting bought out is how you get money. Competing is not an option. But in the end, it's like the only options in tech are to innovate for free (ie not sell out, but get copied) or innovate on your own dime and get paid way less than they make after buying you out.
Personally, I find neither of those exciting.
I hope your project goes well!
How close does someone with the app need to get to the tag before it phones home?(nevermind, FAQ says ~300 ft, which is really good. It seems like if you can see the animal, you can probably get it's beacon id?)
Do you triangulate positions from multiple users, or show a general track of the animal over time?
Are you partnering with big driving orgs (ups, Uber, etc) or parks departments to get more readers on the streets?
What's your revenue model?
There's a reason you don't really see dogs wearing GPS collars - even with LTE-M, the experience is still not good and I don't think there's product market fit.
Absolutely - partnering up with Ride shares is on my roadmap, as well as sticking antennas in Drones and I'm filing a patent for automatically dispatching rideshares that can triangulate a missing pet even if there's no other sensors around.
I guess not many people still have cordless phones? Or they have the tech to avoid it now?
Nice typo.
Boy is bezos smart
