Tablet without wifi

Given the subject matter being "scientific" is unlikely to help (imo).

The OP doesn't trust mobiles either..

Mobile phones are in airplane mode if not used.

Hardly a surprise as mobile phones emission is much higher than WiFi.

The topic is how to avoid/reduce EMF that apparently causes problems to the OP. It's absolutely OOT and not our business whether the problems are real or imaginable.

Later, but before your post, she specified avoiding EMF, but you suggested using much more strong EMF instead of week WiFi.

The idea of avoiding EMF is completely ridiculous you would have to avoid all sources such as Mains electricity, Radio, TV, Mobile Phones, Microwave ovens, WiFi, Infra-red, Visible light, Ultraviolet, X-rays.

You would have to in a remote area where you couldn't pick up and radio phone or tv signals in a house with no electricity and wear a space suit all the time. Even then you might not avoid it.

The OP knows well enough how to avoid EMF - avoid any WiFi and have the phone in airplane mode (not sure why not off as a phone in airplane mode may just as well be off),
Which is what I pointed out.

The original request was for a tablet without wifi and that has been pretty much answered too - OTG cable and USB ethernet adapter + doubtless some jiggery pokery to get it working.

Now the thread appears to have broadened into whether of not such radiations are harmful (no evidence) and why some feel ill when they know WiFi is on (consensus seems to be psychosomatic).
Science has already answered the question of harm and pointing out the findings to someone convinced otherwise isn't going to get anywhere.

Nothing ridiculous with reducing it. That's what we do by using sunscreens, led screens for X-rays, steel grids in microwave oven windows etc.
However, it is ridiculous to put mains 50Hz and X-rays in one basket and concentrate on frequencies while absolutely ignoring the power.

You would have to in a remote area where you couldn't pick up and radio phone or tv signals in a house with no electricity and wear a space suit all the time. Even then you might not avoid it.

I don't think that space suits protect from 50Hz EMF. There is no point.

Not sure?

I don't see any point in pointing this out (pun intended).

Exactly. Ebooks can be loaded, Amazon Prime/BBC iplayer content downloaded for offline use, even Google maps is going offline (inc. navigation) shortly. Games don't need you to be online most of the time eithe.

There's loads you can do with an offline tablet

I don't dispute that, but I had assumed that at least some of the functions required by the OP's DC need online access.
It would help if the OP could enlighten us on that.

In this case the tablet will emit 3/4g signal that is much more powerful than the signal it receives. I guess much more powerful even than wifi signal because of the big distance and the cubic law governing the power needed.

I think you mean the inverse square law Grumbler ?

For a point source it's proportional to the inverse square of the distance, it's not a cubic function.

Yes, and exactly for these some functions the OP wanted wired LAN access instead of WiFi.

Yes, you are right, it's square, not cube
Re directly/inversely, what I meant was that for the source the power needed to reach the receiver is directly proportional to the square of the distance to the receiver (mast).
