The following table shows recommended test cases for radiated LTE-M non-signaling mode.
| Mode | Test item | Test specification/ID | Expected result | Note |
|---|---|---|---|---|
| LTE-M TX | LTE antenna efficiency and radiation pattern at TX frequencies | See nWP033 - nRF9160 Antenna and RF Interface Guidelines | >50% | For analyzing antenna efficiency by using an RF signal generator as the signal source |
| Total Radiated Power (TRP) | Conducted TX power - antenna efficiency | For analyzing antenna efficiency by using Device Under Test (DUT)-internal TX as the signal source | ||
| LTE TX isolation to GPS LNA input | Isolation >30 dB | Isolation from LTE antenna to Global Positioning System (GPS) Low-Noise Amplifier (LNA) input at LTE TX frequency | ||
| LTE-M RX | LTE antenna efficiency and radiation pattern at RX frequencies | >50% | ||
| RSSI scan2 | Signal level -90 dBm1 | RSSI < -105 dBm | Expected RSSI reading of average noise floor |
