Software Implementations

  • minimum delay
  • bug free
  • low memory footprint
  • direct GPU capabilities (look next)
  • unique GPUDirect driver for SDR PCIe cards
  • data produced/consumed by the SDR card are directly transferred to/from NVIDIA GPUs (no CPU intervention & delay)
  • expose GNU Radio telecommunication standards implementations as normal network interfaces
  • currently supports 802.11, 802.15.4 interfaces
  • multiple (adjacent) concurrent channels (8 MHz) in a single transmitter (limited only by the sampling rate/bandwidth)
  • fully software solution - CPU based + GPU based versions
  • compatible with all SDR devices
  • fully software solution - CPU based
  • supports 5, 10, 20 MHz channels
  • compatible with all SDR devices
  • fully software solution - CPU based
  • supports 2.4 GHz & sub-GHz bands
  • compatible with all SDR devices
