DECT is a worldwide established standard for cordless telephony. DECT is a sophisticated process which features high voice quality, supports seamless handover when switching cells and enabling access to numerous features of modern TC systems. DECT can further be used with encryption and tap-proof and is compatible between manufacturers.
Since phone services are now integrated in the IP world, it’s desirable for the IP standard to have an equivalent solution for cordless telephony. Wi-Fi technology is only suitable to some extent and has some system limitations. Voice-optimized Wi-Fi standards are currently still in the works. IP-DECT already offers an approach for connecting cordless telephony to the IP infrastructure now.
