Osomcom POCSAG

I already have been working in a new hardware version. 

This new hardware use a ARM processor instead of a PIC, has USB and TCP/ETHERNET support and can modulate not only in digital modes but also in analog. That means that is not limited to be used for POCSAG but can be used with  other protocols like APRS, FLEX or just analog FM for voice transmission.

The first three boards have been already built and I am in process of developing the firmware. So far I have been able to transmit digital FSK packets and analog NFM voice transmisions. In the next week I hope to be able to build the entire POCSAG stack and for the next week I will develop a simple APRS stack.

I already built a first prototype of the hardware and software. With it, you can deploy a fully functional network with as many users, groups, nodes/antenas, etc as you like.

However, there is still a lot of work to be done. 

From the hardware part, the most important thing is the power of the BTS. 20mW (14dBm) is enough for deploying a small home network but not enough for larger ones. I expect to put something between 500mW and 1W for a future revision.

Also, a TCP-IP support in the BTS boards is something desirable so the BTS and BSC can be integrated in a single board and there is no need of using a Raspberry PI.

From the software point of view, the next feature I would like to add is anticollision support to avoid collisions between close BTS.

Uploading and updating the details! 

I am a little bit late for participating in the contest... but I am trying.
