The term Spurious emissions is used for simplicity elsewhere in the ETSI EN 301 390 but with the more broader meaning of "unwanted emissions in the spurious domain" introduced by Recommendation ITU-R SM.329 [1] for clarifying the Radio Regulation definitions and the application of recommended limits for all unwanted emissions; it also recommends that spurious emissions limits apply to all unwanted emissions falling in the spurious domain.

Therefore the present document deals with limits for unwanted emissions in the spurious domain at antenna port of Digital Fixed Radio Systems (DFRS) as defined by Recommendation ITU-R SM.329 [1] and CEPT/ERC Recommendation 74-01 [4] and ECC Recommendation (02)05 [5].

Moreover it covers immunity characteristics at receiver's antenna port.

Scope of the present document is to define specific limits at antenna port for spurious emissions domain and receiver immunity for suitable inter-working of Digital Fixed Radio Systems (i.e. Point-to-point and Multipoint systems) in the same or in different frequency band whenever allocated to Fixed Service in the range 9 kHz to 300 GHz.

However systems with fundamental emission below 30 MHz are not considered relevant for Digital Fixed Radio Systems and are outside the scope of the present document.

Spurious emissions domain levels and immunity performance at antenna port are also relevant to essential requirements under article 3.2 of Directive 1999/5/EC [i.12] on Radio equipment and Telecommunication Terminals equipment (R&TTE).
