Mesh Repeater
From SUWS-wiki
This is a draft of a Mesh Repeater Idea.
There could be a central transmitter to cover campus, with mesh nodes used around campus as just receivers, but coverage could then be filled in with mesh nodes around homes.
Mesh Nodes
Pi!
1st antenna -> rtl-sdr -> rtl_fm -> audio streaming to central server
audio from central server -> PWM TX -> 2nd antenna
