2 Determine Root Cause

If the range is not meeting the expected distance based on the results in Section 1, the root cause needs to be determined:

Poor range could be caused by one or more of the following factors:

  • Poor sensitivity in the receiver
  • Poor TX output power
  • Poor antenna design (matching)
  • Not optimal settings

The measurement methods depend on what type of equipment you have available.

It is highly recommend for the measurements to use SmartRF™ Studio to control the DUT. If that is not possible, use unmodified settings and code from the software or unmodified code examples before testing with the settings that are used for the product. This is to ensure that the testing of the hardware is done with good known software.
