1
Maximum Power:
The continuous current during maximum data rate with the radio transmitter at
maximum power.
2
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.).
3
Inrush Charge:
The total inrush charge at power on.
