The UmTRX platform that is at the heart of Fairwaves base stations was designed from the outset to have two fully independent transceivers. Since this would mean that we could hit the dual-ARFCN (channel) sweetspot for many target use cases and have a clear advantage over single transceiver solutions, some of which are able to support two channels but with serious limitations and reduced performance.
Thanks to our dual transceiver architecture and the Osmocom software it is now possible to support two independent BTS on a single UmTRX or Fairwaves UmSITE, which may be configured for different bands or even networks.
