Tranmission 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 (V1.1.1)
"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 ERC/DEC(99)15 [5] and draft CEPT/ERC Recommendation ECC/REC(01)04 [56]. 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]: ""Digital Video Broadcasting (DVB); Multipoint Video Distribution Systems (MVDS) at 10 GHz and above""; EN 301 199 [2]: ""Digital Video Broadcasting (DVB); Interaction channel for Local Multi-point Distribution Systems (LMDS)""; ITU-R Recommendation F. 1499 [3]: ""Radio transmission systems for fixed broadband wireless access based on cable modem standard""; IEEE P802.16 (D4) [57]: ""Local and Metropolitan Area Networks - Part 16: Standard Air Interface for Fixed Broadband Wireless Access Systems"". It is likely that the frequency assignment criteria in this band will be based on ""frequency blocks"" according to draft CEPT/ERC Recommendation ECC/REC(O 1)04 [56]@ 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 RTTE 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 RTTE 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 1999/5/EC Directive (RTTE) [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."
