This seems like a great technology to build resiliency and redundancy in a community, especially for places where cell service is spotty, or in the odd event where normal lines of communication are blocked.

The LoRa boards can be easily powered with a small solar panel for continuous use, and if put in a high enough place with a good antenna, they can have a surprisingly long range!

In addition to being genuinely useful, they also seem like they'd be a lot of fun to experiment and play around with, printing cool 3D cases for them, or designing a better antenna or repeater setup.

If and of you already have experience with LoRa, I'd be interested to hear your thoughts! :D

I have a question about how easy the signal is to block. I live in a somewhat mountains, densely forested area. Do devices need to have direct line or sight to communicate? Wanted to set this up as a potential back up communication source for grid outages and keep a device in each car.

You'd really have to test it, it's a lower frequency (915mhz in US) so it should go much further than WiFi. Many people are putting them on roofs and in trees to get better range and then there's a whole world of antennas.

But when we're talking antennas, do I need to get a big one that I need to try and get above the tree line, or does it boost signal penetration?

@McFarius @jared So many innuendoes, I hardly know where to start.
