actually ............

the " next " generation of cordless phones will be UWB phones
operating in the 5 and 10 gig spectrum. ( with uwb , frequency is
not specifically relevant , only the general band they operate on )
.. the " past " generation of cordless phones , operating at 2.4 gig
hz , was discontinued by asian makers last year sometime ( or
before for some ) , to tool up for the " current " generation of 5
gig digital ( all 5 gig phones are digital or spread spectrum )
cordless phone production. plain digital UWB transmissions are 10X
more secure than the best spread spectrum radios / phones.
consumer scanners could not detect spread spectrum phones and the
new UWB radios will be MUCH harder ( 10X ) than spreaders to find.
no known available radio equipment ( not even watkins johnson
or Racal ) can detect UWB transmissions from a distance yet.
( even old watkins johnson could find spread spectrum carriers , tho
not decode the digital modulation codec )

tho the military has had UWB radios deployed in certain applications
for more than 10 years now , they have still NOT deployed
surveillance
equipment , in the field , which can detect UWB. rumors have it
that a few communications eavesdropping satellites already have
UWB capability ...... certain other people , in the know , say it's
only use / response to the " current " deployment of military UWB
radios and not general UWB eavesdropping equipment .
more remains to be seen about military UWB .... probably be years
before much gets leaked into the civilian sector about this state of
the art equipment.


type " UWB radios "
or
" UWB cordless phones " into Google
for more up to date info .......

The next generation of cordless telephones
will operate at the 5.8 GHz

The frequency range is either
5.725-5.825 GHz or 5.725-5.850 GHz

Google "5.8 GHz cordless phones" for more info.
