Transmission and Multiplexing (TM); Multipoint equipment; Radio Equipment for use in Multimedia Wireless Systems (MWS) in the frequency band 40,5 GHz to 43,5 GHz; Part 1: General requirements

Scope

The present document specifies the minimum requirements for equipment and system parameters, including parameters
necessary to plan co-existence, of MWS (Multimedia Wireless Systems) operating in the 40,5 GHz to 43,5 GHz
frequency band and used for a range of applications including telecommunication and entertainment services. When
MWS equipment is not intended for telecommunication purposes (e.g. for entertainment services), different
requirements related to, for example, environmental conditions (see clause 4.4), power supply (see clause 4.5) and
synchronization interfaces (see clause 4.7), may be applied, provided that guaranteed values of parameters necessary for
co-existence with other MWS systems are met.
The present document is applicable to system and equipment parameters required to be able to plan the radio
inter-operator co-existence of a number of possible solutions for implementing MWS in the 40 GHz frequency band
according the CEPT/ERC regulatory frame based on CEPT/ERC/DEC(99)15 [5] and CEPT/ECC/REC 01-04 [55].
Besides specifically designed multipoint Fixed Digital Radio Systems (FDRS) like that in the scope of ETSI
Project (EP) BRAN, some other solutions, derived from standardized technology, are already documented, and include
systems that align with:
• EN 300 748 [1];
• EN 301 199 [2];
• ITU-R Recommendation F.1499 [3];
• IEEE 802.16 [56].
It is likely that the frequency assignment criteria in this band will be based on "frequency blocks" according to
CEPT/ECC/REC 01-04 [55], therefore the radio frequency co-ordination parameters specified in the present document
may be subdivided into two categories:
• those detailed in the present document, related to the minimum requirements for frequency co-ordination of
various systems deployed by an operator inside the same block of frequency. Although these are not all regarded
as "essential R&TTE requirements", they are specified as ETSI "minimum voluntary parameters" for all MWS
systems which will co-exist in this band. Their relationship with the "essential R&TTE requirements" will be
detailed in part 2 of the present document;
• those related to adjacent "block-edge" interference control; these will be considered as "essential requirements"
for the application of Directive 1999/5/EC (R&TTE Directive) [4] and detailed in part 2 of the present
document.
The parameters specified in the present document apply to both FDD (both half and full duplex) and TDD systems.
