Frequency Band Maximum Total Transmit Power

Band 38 (2.6 GHz) 2575 to 2615 120 W Band 41 (2.6 GHz) 2575 to 2635 120 W Band 40 (2.3 GHz) 2302 to 2400 160 W

2.7 Static Sensitivity

Table 2-6 Static Sensitivity

Frequency Band Static Sensitivity

Band 38 (2.6 GHz) 2575 to 2615 -103.5dBm@1RX Band 41 (2.6 GHz) 2575 to 2635 -103dBm@1RX Band 40 (2.3 GHz) 2302 to 2400 -103.5dBm@1RX

As recommended in 3GPP TS 36.104, LTE receiver sensitivity is measured under a 5 MHz channel bandwidth based on the FRC A1-3 in Annex A.1 standard, where the modulation scheme is QPSK (R = 1/3) and the system bandwidth is 25 resource blocks (RBs).

2.8 Power Consumption
