Electromagnetic compatibility and Radio spectrum Matters (ERM); Wide band audio links; Part 2: Harmonized EN under article 3.2 of the RTTE Directive

Spectrum used within the frequency bands 703-733 MHz (i.e. FDD uplink) and 758-788 MHz (i.e. FDD downlink) as well as within the 738-758 MHz frequency band for downlink-only (if applicable), for digital terrestrial television broadcasting below the 694 MHz band edge, for terrestrial systems capable of providing electronic communications services above 790 MHz (both uplink and downlink), for PPDR radio communications in the 700 MHz frequency band (both uplink and downlink), and for M2M radio communications in the 700 MHz frequency band (both uplink and downlink).

Pursuant to Article 3(1)(b), the frequency arrangement within the frequency bands 698-703 MHz, 733-736 MHz, 753-758 MHz and 788-791 MHz for use in full or in part for PPDR radio communications shall be as follows: the mode of operation shall be Frequency Division Duplex; the duplex spacing shall be 55 MHz with terminal station transmission (PPDR uplink) located in one or both of the frequency band 698-703 MHz and 733-736 MHz, and base station transmission (PPDR downlink) located in one or both of the frequency band 753-758 MHz and 78 ...[+++]8-791 MHz, respectively.

Using the 2 010-2 025 MHz frequency band for video links and cordless cameras has the technical and economic advantages of benefitting from the neighbouring 2 025-2 110 MHz frequency band, which is also used for such links and cordless cameras in a number of Member States and is identified in the ERC Recommendation 25-10 as a recommended tuning range.
