DECT (Digital Enhanced Cordless Telephone) standard is a boundary milestone of the long-term development. Since from beginning, this system was designed for wireless telephony in consideration of GSM standard and with connections to other networks. It is not proper to consider this system as a replacement of already existing networks, but as creation of a bridge between wireless and cellular technologies.
DECT is full digital system, transparent for PSTN services, providing mobility in user’ premise (home, work). Coverage is realized by picocells with small cells (radius approximately 50 m), channel selection and channel allocation is dynamic (DCS/DCA), handover of calls is without interruption, provides roaming. Data transmission rate is 24 to 522 kbps (2 Mbps in the future). System has big capacity (10 000 Erl/km2). This system is very flexible, because of predefined profiles, which enable cooperation with other networks. Primarily, DECT system was prepared for radio coverage of small areas and for cooperation with GSM network, which is not constructed for such small areas.
