How to measure LTE signal strength?

[Bradley_R]

Ive used LabView for years but have been away a while.  so much is new.    Can the USRP be used for testing LTE mobile signal strength? and decode various fields like mibs and sibs? signal to noise?  CIR?  if not, is there something that is able to?

thanks

Hello Bradley,

Here is a short video showcasing one application involving NI Software Defined Radio for an 8x8 LTE MIMO, along with an article describing the application:

There is a lot of additional information about USRP available at the following sites:

Note that the LTE application above utilized the FlexRIO with FPGA in their system.  Using the FPGA allows you to fully customize your I/O to match the needs of your application, such as ensuring you have the bandwidth to handle LTE.  USRP products have tunable center frequency options from 50 MHz to 6 GHz, which includes the frequency spectrum of LTE measurements.  What exactly do you want to try and do with USRP and LTE?  Are there any products in particular that you are interested in?
