1. With an impedance of Z
LOAD
=50 at the antenna connector.Measured at 25°C at 3.8V - except for Power
Down ratings that were measured at 3.0V.
2. Measurements start 6 minutes after switching ON the module,
Averaging times:
SLEEP mode - 3 minutes, transfer modes - 1.5 minutes
Communication tester settings: no neighbour cells, no cell reselection etc., RMC (reference measurement
channel). Note that SLEEP mode is enabled via AT command AT^SPOW=2, 1000, 3
3. The power save mode is disabled via AT command AT^SCFG=”MEopMode/PwrSave”, “disabled”.
4. Communication tester settings:
Channel Bandwidth: 5MHz
Number of Resource Blocks: 25 (DL), 1 (UL)
Modulation: QPSK
