- Added instructions for LE-LAN operating in the 5150-5250 MHz and 5250-5350 MHz bands;
- amended b) in Section 7.3.1.3 regarding unwanted emissions from transmitters operating in the 5150-5250 MHz band to clarify the requirements;
- Added reporting requirements for equipment implementing transmitter power control in Section 7.1;
- modified transmit power control requirements in Sections 7.3.1.2 and 7.3.2.2;
- Section 7.3.2.1 was amended to introduce labeling requirements for indoor unwanted emissions;
- Section 7.3.2.3 has been amended to clearly indicate the different unwanted emission limits for transmitters operating in the 5250-5350 MHz band;
