The RM520N-GL module complies with the 3GPP Release 16 standard and supports Power Class 1.5, with a maximum uplink transmission power of up to 29 dBm. This provides robust technical support for Enhanced Mobile Broadband (eMBB) and Ultra-Reliable Low-Latency Communications (URLLC).

This article will delve into the technical specifications and configuration methods for the power class of the RM520N-GL module, exploring the steps and key considerations for unlocking the UE power class.

使用后遗症：

1. There may be power coil whine as the power is pushed to the module's maximum allowable power.
2. The uplink power increases, which may slightly reduce the downlink reception sensitivity. However, improving the uplink generally leads to enhanced downlink speeds.
3. The firmware does not overclock; it only locks the module's maximum uplink power. Please use it with confidence.
