2. Meet 3GPP TS 36.521-1/TS 34.121-1 test standard.
Table 13. Conductive Rx sensitivity-CITA
The below table show the sensitivity data of primary only and second only which is defined
in the CITA Test Plan for Wireless Device Over-the-Air Performance V 3.5.2 Table 6-6.This
data could be the reference in the OTA performance evaluation.
