5G - Are We Safe Or Insane?

[Arpiben]

You may worry at very high power such as radars or in the field of EM devices like the one in the picture. Otherwise you are free to take some caution and not to sleep with your mobile device on under your pillow....

Among RF or Microwave people we still use to have jokes about how many of us have more girls than boys.

You're not reading the links, I can tell. Read them all and we can have an advanced discussion. 

 

Are you aware of power and frequencies involved in 5G as opposed to ones used in radars or EM weapons?

Do you worry also about Space or Earth EM radiations? Do you worry when travelling by plane about the radiation you accumulated during your flight or at airport control devices....😉

I am not worried.

Maybe because I am working with microwave/millimeter radio transceivers that are and will be deployed in the future 5G++. Maybe because I used to destroy components with EM pulses in the past.

Electromagnetic waves are generating non - ionizing radiations until ultra violet spectrum.

I just don’t get much of a charge outta that........

In other words Radio Frequencies used in Telecom networks ( Non-ionizing) are less harmful compared to ionizing ones.

Hide the family jewels, they will restart 28 GHz auction soon.

Wish I could bid on some for my block.

 

Not interesting in terms of bandwidth/throughput. Save your money for auctions dealing with frequencies above 80 GHz  😉

Folks in Dane, Wisconsin apparently like it for some reason (if you read the linked article).

Keep in mind that the auction is dealing only with the right to use the frequency band. People operating will then need to pay the telecom regulator an annual fee based on bandwidth and/or capacity used.

Bandwidths or C.S. Channel Spacing are limited (f<60GHz) to:

- 5/10/20/30/40/50/56 MHz (ANSI)

- 3.5/7/14/28/40/56/112 MHz (ETSI)

 

In terms of Throughput you are limited to a max of around 500Mbps per radio channel with C.S=56MHz.

For 5G and future those bandwidths are not sufficient. This is the reason why the trend is for f>=60 GHz ( E, W and D bands). Due to C.S up to 2000MHz those bands allow rates up to 10 Gbps per radio channel. That was my point when stating that 28GHz was not the most interesting.

 

Anyhow since millimeter waves are more sensitive to rain/snow traffic will be carried in frequency aggregate mode sharing same antenna. For example 18/80 GHz dual carrier.

In other words there is still need for such "lower" bands like Wisconsin case. In Europe, the frequency spectrum is already congested up to 40 GHz.

Just a few facts:

1. Nokia is the owner of Bell Labs.

Bell Labs are fully involved in 5G.

The reasons of Huawei's troubles are more at a political/strategy level than technical.

2. 5G untested frequencies? -> False

Military have ben using E, W, D bands (5G and +++) since quite long.

Is there any evidence of Huawei actually doing anything nefarious?

 

No real evidence only some governments waking up and realising too late that Huawei the dragon:

- is Nr.1 Telecoms equipment manufacturer (since 2012)

- has already a dominant position in terms of equipment deployed in most of World 's Telecom networks.

- is supposed to have more than 150.000 employees.

- is now innovating instead of following / copying others.

- etc...

Banning Huawei from 5G bids is one thing. Replacing the supposed nefarious already installed equipment is unrealistic (many years)...

All true, but why is nobody similarly afraid of Cisco? For all you know, their routers could all be sending data to the NSA.

 

Correct. Double standard, two-tier policy approach...😉

Or your Wi-Fi 6 beamforming  

 

With DMA thunderbolt attack we may add beam steering to @Ralf11's Wi-Fi. 😉

 

[Arpiben]

After phase alignment they might start looking at serious concerns like 5G power consumption/efficiency per bit carried. 😉
