Even worse EMFs on this phone technology?

I just wanted to see if anyone has heard of this and if you have any knowledge on the extent of the EMFs.

It would look like it would be even worse on EMFs than a regular cordless phone, but I don't have enough understanding of the subject. I am not even considering it I just wanted to see if anyone had any understanding of it. I will also see what I can find out by googling it.

I had told my cousin that I was having to give up cordless and there must have been a mixup in the translation. Her husband sent me that link and said she had told him that we were giving up our land line.

Doesn't this look like even worse EMFs?

Thanks,
