DECT Frequencies and Frequency Bands
- summary of the main DECT frequencies and frequency bands.
DECT technology tutorial includes:• DECT technology tutorial • DECT standard / specification
• DECT RF air interface
• DECT frequencies and bands
• Security, encryption, authentication
The DECT frequencies and DECT frequency bands are normally allocated to DECT technology.
The most common DECT frequencies are from 1880 - 1900 MHz. This DECT frequency allocation is the most widespread and used in Europe. This DECT spectrum is unlicensed and technology exclusive, and this ensure ensures almost interference free operation. The use of these DECT frequencies allocated on a primary basis contributes to the very high spectral efficiency of the technology.
The bands 1900 MHz to 1 920 MHz and 1 910 MHz to 1 930 MHz are also in common use as DECT frequencies in many countries outside Europe. In the US the DECT frequency allocation is 1920-1930 MHz. This is known as UPCS band. However this DECT frequency allocation is not an exclusive frequency allocation, but it is generally sufficiently free of other users to achieve similar interference-free operation.
The DECT frequency allocations in Europe of 1900 - 1920MHz are shared with shared with UMTS TDD, while the DECT frequencies between 1920 - 1980 are shared with shared with the uplink of UMTS FDD.
The frequencies between 2010 - 2025 MHz have been envisaged as a possible additional DECT frequency band by IMT-2000 although they are not in use yet.
