Digital enhanced cordless telecommunications (Digital European cordless telecommunications),
ECT Theory & Details Communication Typical Frequency Range: 1880 – 1900 MHz (Europe) General: Digital enhanced cordless telecommunications Modulation: TDMA, GMSK, GFSK Combination method. DECT uses MC (multi carrier): 10 RF channels; channel 10 at 1881.792 MHz; other channel numbers in decreasing order at 1.782 MHz intervals. DECT uses TDMA (time division multiple access) within a channel: 24 timeslots spaced 10 ms apart; 1 – 12 downlink, 13 – 24 uplink. DECT devices automatically look for the carrier that gives the best transmission quality (dynamic channel selection / allocation). DECT uses TDD (time division duplex) In full duplex mode for teleph-ony in 2 channels always separated by 5 ms and also on different frequencies. The bursts are GMSK or GFSK modulated (Gaussian minimum shift keying; Gaussian frequency shift keying). Up to 23 channels can be bundled for data transmissions. At least one channel must remain for the backward path
usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the universal standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2.<ref name=rohde>Template:Cite web</ref>
