RF conducted performance test is recommended to be performed in the R&D phase to verify the RF performance of the end product. A verified conducted test provides a solid background for entering radiated RF tests.
The LTE-M and Narrowband Internet of Things (NB-IoT) tests described in Signaling mode and Non-signaling mode are based on specifications in 3GPP TS 36.101.
The tests should be performed with a 50 Ω test connector or soldered cable.
