No, lower prequency is correct Worldwide DECT standars is 1800/1900
mhz - North America is Â*DECT6.0 - running at 1920/1930mhz.
Significantly lower frequency than the older common5.8ghz, but higher
than the old 900mhz

BTW, at one time 900MHz cordless phones were NEW. Most used 54MHz.
Also, there was no way to change the channel in case of interference.

Then what is that button for that says "change channel".
On a 54mhz phone, or a 900?
The first 54 mhz units were single channel - then the fancier units
like the Compander Plus from Sanyo went to 25 channel auto switching
(spread spectrum)
