Hi Elmat,

The PlanetAnalog article on iW modulation took me back two decades to xG, a Florida based radio modulation whose demonstration involved a bus ride from the base of the tower to a "distant" receive site, no cellphones allowed. Needless to say, the line of sight distance between tower and receive sight was much less than the distance the bus traveled around the plantation.

The article compares iW at 3 GHz to QAM at 28 GHz, which inherently is
69.5 dB pathloss to 88.9 dB pathloss, a difference of 19.4 dB due to frequency alone.

It is good to see software defined radios in the wild, but I take the claim of "reducing the need for bit checking and extreme transmission power levels" with a grain of salt as production Wi-Fi does more with low transmit power levels.

IEEE 802.11ax features 1024 QAM up to eight spatial streams

802.11ax and 5G cannot flop, but what is promised can change to align with what is delivered.
