Everything on the RF side runs through a software-defined radio. Below are the SDRs 1xBTS supports and a sample of the handsets it's been tested with. Most CDMA2000 1x phones should work; EV-DO needs a handset, modem, or data card with HRPD support.
The primary development target. Full sample-rate and timing discipline over UHD, including combined 1x + HRPD composite operation.
Ettus Research ↗Native backend with configurable stream buffers, including combined 1x + HRPD composite operation.
Nuand ↗Native mode with RX sample-delay compensation for 1x operation.
Lime Microsystems ↗Generic SoapySDR path for other radios. May work for 1x, but isn't regularly exercised and is not the primary EV-DO path.
SoapySDR ↗Build steps and dependencies are on the Download page.
A sample of what we've run; many more CDMA2000 1x handsets work. For EV-DO testing, use a hybrid handset or data card that supports HRPD Rev 0 or Rev A.
