Foreword This European Standard (Telecommunications series) has been

16、produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document contains the minimum technical requirements to ensure compatibility of products and conformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are not require

17、d to inter work at radio frequency (i.e. no common air interface). The present document defines the requirements radio-relay equipment and associated interfaces. The present document is part 2 of a multi-part deliverable covering the Fixed Radio Systems; Point-to-multipoint equipment; Point-to-multi

18、point digital radio systems in frequency bands in the range 24,25 GHz to 29,5 GHz using different access methods, as identified below: Part 1: “Basic parameters“; Part 2: Part 3: Part 4: Part 5: “Frequency Division Multiple Access (FDMA) methods“; “Time Division Multiple Access (TDMA) methods“; “Dir

19、ect Sequence Code Division Multiple Access (DS CDMA) methods“; “Multi-Carrier Time Division Multiple Access (MC-TDMA) methods“. Parts 2 to 5 are intended to be used in conjunction with part 1, describing the basic parameters common to all access methods. A basic description of the different access m

20、ethods and a comparison among them are provided in TR 101 274 5.

23、fixed services operating in the band 24,5 GHz to 29,5 GHz (CEPT Recommendation T/R 13-02 6). Only sections specific to FDMA are described in respect to the clauses stated in EN 301 213-1 i. The FDMA P-MP system will transmit a RF-signal from the customer site to the Central Radio Station (CRS) only

24、utilizing a spectral bandwidth corresponding to that capacity which is requested from and assigned to the customer by Preassigned Multiple Access or by Demand Assigned Multiple Access. The Central Radio Station receives from each customer site a single modulated carrier being processed independently

25、 within the CRS. Thus the CRS is receiving a FDMA P-MP signal. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
