Is the communication range of the particle mesh published anywhere?
You should expect that point to point range of the mesh network, which operates at 2.4GHz, to be roughly
comparable to bluetooth (tens of meters). It is also designed to co-exist with Wi-Fi in order to maximize range.
The great part about mesh, however, is that the endpoints do not all have to connect to a central network gateway like with Wi-Fi. So, the effective range of the network can be extended greatly by daisy-chaining endpoints together which allows messages to hop between mesh devices until it reaches a network gateway.
