[Battlemesh] Amazon 900Mhz Sidewalk mesh?

It's likely not going to work this way in Europe due to spectrum regulations
on those frequencies.
And in Europe LoRaWAN starts to become important. Simply because we already have a dense
network in the Netherlands and because German companies are starting to deploy LoRaWAN
Gateways we will possibly soon have an existing infrastructure.
It would be quite stupid if Amazon wouldn't hop on that train, but sometimes they
make stupid decisions (has anyone ever used the dash buttons for ordering something)?

By the way I think these LoRa-Mesh approaches are a disaster if deployed
in urban areas. I see it this way: The regulatory institutions have limited the
time a LoRa device can transmit due to a good reason. Too many transmissions will jam
the bands. If the WLAN is bad, what do people do? Buy a repeater...
I hope it will never end like this with LoRa.

A LoRa message should be transmitted once to a gateway and not be repeated several times.
And if it's one of these non-standard brain-dead Semtech chips... Please, don't
buy it :).

Best,

Vincent
