Hello @tkamimura4 I can check into why the data sheet power consumption was updated from 22W to 18W, perhaps it was a typo, however I see in the MR56 data sheet there is still a reference to 22W in one section but 18W in another. I will get the documentation team to address this. Stand by and hopefully that will be corrected shortly. I will confirm, but my guess is the MR46 is 18W maximum, and MR56 is 22W maximum since it is 8x8 compared to the MR46 which is 4x4.
However, to answer your question, you are correct, there is no change to the specification, both the MR46 and MR56 do require 802.3at PoE+ power in order to operate properly.
