Determined using the internal LoRa antenna of 0.85 dB gain. If using an external LoRa antenna, adjust levels to
ensure maximum values are not exceeded.
Important: 2G fallback can cause issues when operating on battery power. If you have a SIM that supports 2G
fallback, consult your carrier for options.

Cellular Radio Models

Note:
Multi-Tech Systems, Inc. recommends that you incorporate a 10% buffer into the power source
when determining product load.
Constant Current Mode: Voltage during charging in constant current mode was between 3.2 VDC
and 4.0 VDC.
Full Battery Mode: Voltage was between was 4.04 VDC.
Maximum Power: The continuous current during maximum data rate with the radio transmitter at
maximum power.
Tx Pulse: The average peak current during a GSM850 transmission burst period or HSDPA/LTE
connection. The transmission burst duration for GSM850 can vary, depending on what transmission
scheme is being deployed (GPRS Class 8, Class 10, GSM, etc.).
Inrush Charge: The total inrush charge at power on.
