Ability to run GSM network on any frequency¶

Since OsmocomBB does support SDR PHY now, the working frequency range is only limited by hardware capabilities. In other words, the "ARFCN -> frequency" calculation may be modified to add a constant frequency offset, so this will allow one to run both base stations and (OsmocomBB-based) mobile stations on any frequency (e.g. in 2.4 GHz WiFi band)!

Of course, regular GSM phones are not able to "see" any networks outside the known predefined ranges (e.g. GSM-900, DCS-1800), so they wouldn't be able to camp to a network running on some shifted frequency. So we have the following use cases in our mind:
