Spirent and National Instruments (NI) have partnered to create world-class solutions for 4G LTE & Software Defined Radios (SDR). The combination of Spirent’s software-based algorithms along with NI USRP hardware enables the user to do so much more.

SDR is a wireless communication device in which the transmitter and receiver modulation/demodulation occurs in software. As a result, the functionality is modified or changed by software alone, eliminating the need to make any physical changes to the hardware.

Commercial
SDR is used to monitor commercial communications on several different frequencies, including VHF, UHF, and HF. Several different protocols – such as CDMA, GSM, Bluetooth, WiFi, and 4G LTE – can be operated at the same time while offering the ability to monitor a large portion of the RF spectrum while supporting these protocols.

Military
As SDR technology has evolved it is solving the problem of needing multiple devices to test military communication applications. Military SDR requires true phase coherency and known latency for multiple input/multiple output (MIMO), Radar and Beamforming systems.
