Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
support a lesser number of users or do not implement the LIC algorithm are required to use a lower
threshold. EUT transmit power is also limited, and the thresholds are adjusted to normalize the anticipated
interference generated by an EUT in proportion to its transmit power.
