2.4G wireless mouse signal and bluetooth 4.0 mouse signal, which one emit less energy
hi,
anyone know what is the magnatitude of the 2.4G wireless mouse signal and bluetooth 4.0 mouse signal ?
I want to know which one is stronger to human body so that it is not going to hurt me.

"Mobile Phones
The radiation emitted by mobile phones falls into the category of non-ionising radiation – lower energy radiation that doesn’t have enough energy to damage our cells. Visible light, infrared, microwaves and radio waves are all forms of non-ionising radiation."
actually from time to time you will hear news that even doctor said mobile phone can cause cancer, this is my concern.

actually what I am worrying about is, I have:
1) 1 x wireless keyboard
2) 2x wireless mouse
3) I will turn on iphone as the AP,
so when they ALL OPERATE at the SAME time, it can hurt my healthy, this is it.

Yes, you hear that news but is there actually any evidence?

Your question is about bluetooth and WiFi not mobile phones
And the "strength" of the signal is about the same with both.
If you have concerns about relative risk though why not switch to a wired version?

Your concerns are not founded by scientific fact but by rumour mongers that love to spread fear, uncertainty and doubt,

"f you have concerns about relative risk though why not switch to a wired version?"
exactly what I am trying to do!
the new wired MS keyboard
"And the "strength" of the signal is about the same with both."
oh.. 2.4G mouse signal and bluetooth 5.0/4.0 release same amount energy ?
so why new bluetooth so call low energy bluetooth ?
David Johnson, CD
you can say it ! but one thing I believe is true is, it is since a lot of mall or home use WIFI, more and more people getting crazy ! people easier to scream!
on evident here in my city is one of my workmate, when he is close to an AP, he will feel headache !! he said it to us ! his head bond CLOSED for a long time since born !
so you can see that this kind of energy can hurt a human ! human brain !

tks all.
it seems bluetooth is much better than 2.4G mouse

"Here's some of the more recent science:
https://www.saferemr.com/2015/09/recent-research-on-wifi-effects.html
it say:
In conclusion, exposure towards 2.45 GHz RF-EMR emitted by Wi-Fi transmitter is hazardous on the male reproductive system.
but ONLY to male ? not female ?

"es 14.00 dBm maximum for 2.4g mouse
Max permitted for Bluetooth 4 is -3 DBm"
2.4G mouse should be -14 dBm and bluetooth is -3 dBm so 2.4G is better for human ?

put on your tin hat (farady shield) and stay away from any RF source. Just because a study is published it doesn't necessarily mean that its findings are valid and reproducible and have been subject to peer review. As there are diploma mills that generate worthless degrees there are also scientific paper mills that accept a paper on anything with no peer review. What you are reading is a synopsis of the results and not seeing the procedure used to generate those results. Without knowing how to reproduce the results and to validate the results rather than just using the results to justify a claim. If there was any provable facts the tabloids would have run rampant on this. This would have created such a furor that these devices would be banned the same way cyclamates were banned.
Cyclamates were banned since the use of it would cause cancer. When one examined the study you would have to drink many gallons of soda (sweetened using cyclamates) per day over an extended period and there would be a higher risk than someone that did not consume cyclamate sweetened soda. Tight underwear contributes to a higher loss of sperm vitality than exposure to RF.
My life in the military had more exposure to high levels of RF energy (MEGA/GIGA watts) (RADAR/JAMMER operations) compared to the milliwatts of class 15 RF devices. There is no recorded increase in adverse health effects among the radio/television engineers that work in proximity to high power transmitters.
The only adverse effect I ever had was the rare RF burn.

You've added a minus sign to 14 dBm !
And mobile phones do cause cancer if you smoke too many of them.

non I read the URL from above, it has minor there! that's why I ask!
if it is -14dBM, then wifi 2.4G mouse emit far less energy then bluetooth, agree?

what I can agree is that report is simple and what I want to know if from what DISTANCE from the source is said to be safe, like some mobile phone studies here, just make you head 1 inch from the mobile phone already much safer! radiation magnitude already down by more than 1/2, that's why some Australia product designed for it.

Other than highest divorce rates due to isolated postings and tinnitus from high noise levels the rest was lower than the national average.
