Hello, experts!

Early 2G mobile phones were capable of transmitting at very high power levels, reaching up to 33 dBm. In contrast, 4G User Equipment (UE) operating under power class 3 (PC3) is limited to a maximum transmission power of 23 dBm.

Given this difference, when a 4G-capable device operates in 2G mode, is it able to transmit at power levels exceeding 23 dBm, similar to legacy 2G phones?

Yes, a 4G UE can transmit at power levels higher than 23 dBm when operating in 2G mode, as it follows the power class requirements defined for 2G networks.

There are High Power UEs in 4G that can transmit at 31 dBm or 33 dBm, depending on the power class.
