The present document applies to constant envelope angle modulation systems for use in the land mobile service, using
the available bandwidth, operating on radio frequencies between 30 MHz and 1 000 MHz, with channel separations of
12,5 kHz, 20 kHz and 25 kHz intended for non-speech transmissions (more specifically, transmissions of signals used
to initiate a specific response in the receiver). It applies to non-speech and to the non-speech part of combined
speech/non-speech equipment having an antenna connector.
In the present document non-speech radio equipment is defined as radio equipment transmitting a signal to initiate a
specific response in the receiver. The equipment comprises a transmitter and associated encoder and/or a receiver and
associated decoder. The encoder and/or the decoder may be a separate piece of equipment, in which case compliance
with the present document covers the combination of encoder and/or decoder and transmitter and/or receiver equipment.
The present document is intended to cover the provisions of Article 3.2, of Directive 1999/5/EC [1] (R&TTE
Directive), which states that ".. radio equipment shall be so constructed that it effectively uses the spectrum allocated
to terrestrial/space radio communications and orbital resources so as to avoid harmful interference."
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org/.
