No, actually it is the other way around. DECT 6.0 is far superior to 5.8. It is a night and day difference.
Yes they are.. the clarity is better with the 5.8. and if you happen to have a wireless computer network in your house it doesn't interfer with it.
Digital Enhanced Cordless Telecommunications (DECT 6.0) is a standard that uses the 1.9 Ghz band for cordless phones. It is relatively new in the US market but has been in use in Europe for quite some time. The purported advantage of this communications frequency is reduced interference with and from other devices, most notably wireless networks, garage door openers, microwave devices, baby monitors, etc. Additionally it should offer greater range from the base, enhanced call clarity, and the ability to utilize multiple handsets with a single base unit POTS connection.
Yes
2.5 GHz is better than 2.1 GHz. It is because it is the latest processor. It will be faster than 2.1 GHz.
Of course it is, it is much more faster than the 1.5 GHz processor.
The AMD Quad Core runs at 1.5 Ghz. Multiply it by the amount of cores and you get 6 Ghz. 6 Ghz vs. 3.20 Ghz, which means the Quad core is better than the Intel Pentium 4.
the core 2 duo 2.4 ghz is better. the higher the ghz, generally the faster the computer
Absolutely! The bigger the better!!
3.00ghz would be much faster then 1.80ghz, nearly double the computing power.
Yes, since both use the 2.4 GHz band.
2.3 ghz, higher the ghz, the faster it is. but don't overclock it too high or else your computer will overheat
A faster processor.
