LimeSDR

LimeSDR is an open source, apps-enabled software-defined radio (SDR) platform that can be used to support just about any type of wireless communication standard; it can transmit and receive UMTS, LTE, GSM, LoRa, Bluetooth, Zigbee, RFID, and Digital Broadcasting, to name but a few.

The LimeSDR platform is comprised of a family of boards that range from a highly affordable 2×2 MIMO solution with USB3.0 interface, up to a 4×4 MIMO PCIe board which provides support for adaptive digital predistortion (ADPD) and with GPS for frequency accuracy/stability.
