Thank You, Frank.

Jim and I had a great many conversations about a common interest in a fledgling , but failed

Canadian company that we had high hopes for.

I developed a great respect for his knowledge and interest, and above all, his integrity and kindness.

I certainly will miss him.

Axial aka Jim Kayne was a good member of this forum and I have several discussions with him.

May his soul rest in peace.

Will 5G flop?

One of the most dangerous aspects of the newer GHz frequencies used for the 802.11ad WiGig and 5G cell phone networks is their energy is unable to penetrate the human body.

Some of the GHz waves bounce off your skin and are scattered, while some are converted into heat similar to sunlight - but at much lower power levels.

As a result there's a great danger that these GHz frequencies will never reach your phone or the transmission tower.

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.

linuxfromscratch.org

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

cisco.com

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

Hi Elroy,

The Mobile Manufacturers Forum is engaged on RF safety, especially the newer GHz frequencies.

emfhealth.info

A new SAR standard above 6 GHz is expected in March.

The mm frequency cellphones know which antennas are close to the person, and put more energy into antennas that are no shrouded by the person.

About measuring RF exposure above 6 GHz:
The revised IEEE C95.1 has been published which includes revised limits above 6GHz.

We do have some test guidance from FCC

There'd better be a pay-off at the end of the "playing hard to get".

I own Cisco shares and have been getting very little respect. Just a 3% dividend and a bunch of drama.
