Purpose: Digitially Enhanced Cordless Technology is the newest version of the cordless phone. These phones use a very similar frequency range to cellular phones to obtain a better call signal.
Issues: Cellular phone frequencies are harmful to the body. DECT cordless phones emit radiation 24 hours a day even when you are not using them. Instead, use ordinary landline phones. Or if you are addicted to cordless phones, you have a couple options. If you live in Europe, you may want to use the Orchid low radiation cordless phones or the Siemens Gigaset S675, which only emit a signal when you are using them.
Frequency Range:
- Frequency: Section 4.1.1 ("Nominal position of RF carriers") of the ETSI standard states: "DECT carriers are specified for the whole frequency range 1880 MHz to 1980 MHz and 2010 MHz to 2025 MHz. Carrier positions in the 902 MHz to 928 MHz ISM band and the 2400 MHz to 2483,5 MHz ISM band have been defined for the U.S. market. [...] The most common spectrum allocation is 1880 MHz to 1900 MHz, but outside Europe spectrum is also available in 1900 MHz to 1920 MHz and in 1910 MHz to 1930 MHz (several countries)."
- 1880 – 1900 MHz in Europe,
- 1920 – 1930 MHz in the United States and Canada
- Carriers: 10 (1.728 MHz spacing) in Europe, 5 (1.728 MHz spacing) in the US
- Time slots: 2 x 12 (up and down stream)
- Channel allocation: dynamic
- Average transmission power: 10 mW (250 mW peak) in Europe, 4 mW (100 mW peak) in the US.
Better Option: Whenever possible, use a corded phone. If you must use a DECT phone, then the ECO-DECT Phone by Siemens is a better choice. It transits signal from the base staion to the handset only when in use.
