60GHZ What you need to know about 802 11ad and 802 11ay | Jason Hintersteiner | WLPC Phoenix 2019

Where can I buy any 802.11ay devices?

[@WirelessLANProfessionals]

Hey there, Kwinzman! Qualcomm is offering 802.11ay, 60GHz Wi-Fi chipsets that can support a variety of devices.

@@WirelessLANProfessionals Thanks for the reply! Any developer kits and/or end user devices yet?

[@WirelessLANProfessionals]

Thanks for your questions as well, Kwinzman! The 802.11ay-2021 standard has been recently published by the IEEE, so we're excited to see any developer kits or end user devices soon!

Edge-Core, Cambium, and Siklu now offer 802.11ay product. It's under the Terragraph product name. Turns out though the Qualcomm 802.11ay chip vs. 802.11ad chip isn't that different. Same SISO (not MIMO), still only 16QAM, same 2.16GHz channels, still just channels 1-4. The main differences are: channel bonding (two 2.16 channels to create an even FATTER 4.32GHz channel), the next is the 802.11ad chip was CSMA/CA (traditional 802.11) while the new Qualcomm chip is using TDMA. Also the new chip now supports more PtMP clients (15 vs. 8 with 802.11ad). Also no backward compatibility with 802.11ad. Cheers!

This was interesting…and now I think I understand how the conspiracy theory about 5G and oxygen, may have started! Does the fact that 60ghz can be absorbed by oxygen, do anything negative to the human body? (Could it inhibit a person’s oxygen uptake?) These are sincere questions…thanks for your video. 😀

These radios transmit 25mW or 1/40 of a watt. In radio, there is a thing called FSPL (free space path loss) where the signal significantly drops as you get farther from the point source of the transmitted signal. At even just 1 meter away, the signal has dropped by more than 60dB! This means this 1/40 watt is down to 0.000000025 watt or 1/40 of a millionth of a watt. The signals received in radio are so weak, and because their are too many zeros in front of it, we engineers use dBm instead to better understand truly how weak of a signal we are receiving. There simply is not enough energy to really do anything harmful. The most RF exposure the average human will ever have will be by far, their own cell phone. This because of the very close proximity we are to it. Cheers!
