1
Maximum Power
: The continuous current during maximum data rate with the radio transmitter at maximum
power.
2
Peak Tx Current
: The average peak current during a GSM850 transmission burst period or HSDPA connection. The
transmission duration for GSM850 can vary, depending on what transmission scheme is being deployed (GPRS
Class 8, Class 10, GSM, etc.).
3
Total Inrush Charge
: The total inrush charge at power.
Note:
Multi-Tech Systems, Inc. recommends that you incorporate a 10% buffer into the power source when
determining product load.
