An implementation of Analog cellular networks like A-Netz, B-Netz, C-Netz, NMT, AMPS, TACS, JTACS, Radiocom 2000, IMTS, MPT1327, Eurosignal and more http://osmocom-analog.eversberg.eu/
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
Sometimes the sound buffer (ALSA) returns a few more samples than we sent to it. In this case we return 0, which means that no data has to be sent.

This software implements base station protocol of classic mobile phones. With
radio transmitter and receiver connected to one sound card and a headset
connected to another sound card, it is possible to make and receive calls to
and from mobile phone. With SDR (software defined radio) it can be use without
radio equipment connected to a sound card, and even multiple channels can be
generated simultaniously using SDR. Currently supported networks:
* B-Netz (ATF-1)
* NMT 450 / 900 (Nordic Mobile Telephone)
* AMPS (Advanced Mobile Phone System)
* TACS (Total Access Communication System)
* JTACS (Japanese version of TACS)
* Radiocom 2000 (French network)
* IMTS / MTS ((Improved) Mobile Telephone Service)
* MPT1327 (Trunked Radio) aka known as 'Buendelfunk'
* Eurosignal (ERuRD paging service)
* 5-Ton-Folge (ZVEI 5 tone paging code for pager and siren trigger)
* JollyCom (Unofficial network, invented by the author)
* C-Netz BSC (Connecting to a C-Netz Base Station)
Additionally the following communication services are implemented:
* TV Transmitter with test Images
* Radio transmitter / receiver
* Analog Modem Emulation (AM7911)
* German classic 'Zeitansage' (talking clock)
* POCSAG transmitter / receiver
* 5-Ton-Folge + Sirenensteuerung
