Decide how many nodes/antennas do you want to run!

The current hardware transmits  at +14dBm, enough for covering a small house or up to 100m outdoor. If you need to cover a larger area, you will need to run several nodes.

Create the BTS (transmitters)  hardware!

You will need as many as nodes you want to run.

The schematics and firmware are available at github: https://github.com/RamiroPareja/Osomcom-Pocsag

More information about how to create and configure the transmitter: http://www.t4f.org/projects/osomcom-pocsag/bts

Configure the Raspberry PIs as BSC (node)!

You will need as many as nodes you want to run.

Software can be downloaded from github: https://github.com/RamiroPareja/Osomcom-Pocsag-BSC

Instructions about configuring and running it: http://www.t4f.org/projects/osomcom-pocsag/bsc/

Configure a Raspberry PI or another computer as MSC (Master node)

This node will control the entire network.

Software can be downloaded from Github: https://github.com/RamiroPareja/Osomcom-Pocsag-MSC
