Re: New Long Range Cordless Phones

Michael Quinn commented on this topic:

They are illegal in the US and many other countries. They are in use in mining, logging, and oil drilling in rural parts of Canada and by the oil industry in the middle east and elsewhere.

Not 100 Km. I think they claim 50 Km, which is 30 miles. And there's another with a claimed range of 5.5 miles (9 KM)

Now if you search around you will find things like linear amplifiers for cell phones. These could be probably be used by cordless phones in in the 900 MHz band. Not legally, of course, but that doesn't stop them from being offered on the internet. Google can often find stuff like this, but Ask Sam has been getting a lot of publicity lately.
