DECT provides for voice and multimedia traffic, and contains many forward-looking technical features that allow DECT-based cordless systems to play a central role in important new communications developments such as Internet access and interworking with other fixed and wireless services such as ISDN
DCS/DCA (Dynamic Channel Selection / Allocation) is a unique DECT capability that guarantees the best radio channels available to be used. This happens when a cordless phone is in stand-by mode, and throughout a call. This capability ensures that DECT can coexist with other DECT applications and with other systems in the same frequency.
DECT basic technology and the various profiles enhance the DECT standard, introducing evolutionary applications and services. The GAP profile, for example, ensures interoperability of equipment from different providers for voice applications.
