  • Page 23 TOBY-L2 and MPCI-L2 series - System Integration Manual When a GPRS connection is established, more than one slot can be used to transmit and/or more than one slot can be used to receive. The transmitted power depends on network conditions, which set the peak current consumption, but following the 3GPP specifications the maximum Tx RF power is reduced if more than one slot is used to transmit, so the maximum peak of current is not as high as can be in case of a 2G single-slot call.
