ÖNORM EN 301166-2 V 1.1.1

The present document covers the co-existence requirements for radio transmitters and receivers used in stations in the Private Mobile Radio (PMR) service. It applies to use in the land mobile service, operating on radio frequencies between 30 MHz and 3 GHz, with narrow channel separations (CSP) (less than 10 kHz) and intended for speech and/or data. It is the intention of the present document to cover any Channel Bandwidths (CBW) permitted by CEPT for such systems e.g. 6,25 kHz. In the present document different requirements are given for the different radio frequency bands, environmental conditions and types of equipment where appropriate. In the present document, data transmission systems are defined as systems which transmit and/or receive data and/or digitized voice. The equipment comprises a transmitter and associated encoder and modulator and/or a receiver and associated demodulator and decoder. The present document covers equipment which may use constant envelope or non-constant envelope modulation. The types of equipment covered by the present document are as follows: base station: equipment fitted with antenna socket; mobile station: equipment fitted with antenna socket. Handportable stations: a) either fitted with an antenna socket; or b) without an external antenna socket (integral antenna equipment) but fitted with a permanent internal or a temporary internal 50 RF connector which allows access to the transmitter output and the receiver input. Handportable station equipment without an external or internal Radio Frequency (RF) connector and without the possibility of having a temporary internal 50 RF connector is not covered by the present document. The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [8] (R&TTE Directive), which states that "radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial (...abbr (...abbreviated)
