Due to recent increasing interest in this frequency range, the standard has been revised three times, leading to publication of ver

14、sions 1.2.1, 1.3.1 and 1.4.1. A short description of the differences in FR5 for these versions is given below: V1.2.1: V1.3.1: 3 classes (1, 2 and 3), the RPE for class 3 is specified for V polarization only. 4 classes (1, 2, 3 and 4), the RPE for class 3 is the same as 1.2.1 but it is valid for bot

15、h H and V; class 4 is less stringent than class 3. 3 classes (1, 2 and 3), class 3 give three specifications (3a, 3b and 3c); as class numbers increase, this indicates improved performance. V1.4.1: The RPE for class 3a (equivalent to the class 3 given in versions 1.2.1 and 1.3.1) is now specified fo

16、r V polarization only. The RPE for class 3b (the copolar horizontal polarization values are equivalent to the class 4 given in version 1.3.1) is now specified for both polarizations, and the crosspolar values have been improved. The RPE for class 3c is specified for both polarizations. National tran

20、th Point-to-Point (P-P) systems operating in the frequency range 3 GHz to 60 GHz. Single polarization antennas, dual polarization antennas, dual bandsingle polarized antennas and dual banddual polarization antennas are considered.

Fixed link frequency allocations are in accordance with the WRC-2000 11 as given in ITU-R Recommendation F.746-6 2 and other frequency plans. For the purposes of the pr

35、esent document, the overall frequency range 3 GHz to 60 GHz is divided into six frequency ranges as follows: Range 1: 3 GHz to 14 GHz; Range 2: 14 GHz to 20 GHz; Range 3: 20 GHz to 24 GHz; Range 4: 24 GHz to 30 GHz; Range 5: 30 GHz to 47 GHz; Range 6: 47 GHz to 60 GHz. 5 Classification of antennas W

36、ith respect to antenna gain, two gain categories are applicable: Gain category 1 : those antennas which require low gain for Co-ordination purposes; Gain category 2: those antennas which require high gain for Co-ordination purposes. With respect to Radiation Pattern Envelope (WE), four classes have

37、been identified: Class 1 : Those antennas required for use in networks where there is a low interference potential. Typical examples of a low interference potential might be: - antennas for use in radio networks where there is a low density deployment, and therefore, a low potential for inter- and i

38、ntra-system interference, and where high capacity digital radio is proposed; antennas for use in radio networks where there is a medium potential for inter- and intra-system interference, and where low capacity digital radio is proposed. - Class 2: Those antennas required for use in networks where t

39、here is a high interference potential. Typical examples of a high interference potential might be: - antennas for use in radio networks where there is a medium potential for inter- and intra-system interference, and where high capacity digital radio is proposed; antennas for use in radio networks wh

40、ere there is a high density deployment, and therefore, a high potential for inter- and intra-system interference, and where low capacity digital radio is proposed. - Class 3: Those antennas required for use in networks where there is a very high interference potential. Typical examples of a very hig

41、h interference potential might be: - antennas for use in radio networks where there is a high density deployment, and therefore, a high potential for inter- and intra-system interference, and where high capacity digital radio is proposed. Class 4: Those antennas required for use in networks where th

42、ere is an extremely high interference potential Typical examples of an extremely high interference potential might be: - antennas for use in radio networks where there is a very high density deployment, and therefore, a very high potential for inter- and intra-system interference, and where high cap

43、acity digital radio is proposed. In frequency bands where spectrum congestion is likely to exist, the regulator may insist on the use of higher class antennas. ETSI 8 ETSI EN 300 833 VI .4.1 (2002-1 1) With respect to cross-Polar Discrimination (XPD), three XPD performance categories have been ident

44、ified (refer to clause 6.2, table 1): XPD category 1: those antennas required to have standard cross-polar discrimination. XPD category 2: those antennas required to have high cross-polar discrimination. XPD category 3: those antennas required to have high cross-polar discrimination in extended angu

45、lar region. Electrical characteristics The antenna manufacturer shall state, for each antenna type, the frequency band of operation and antenna gain at least at the frequency band edges and at mid-band. An antenna which employs a radome shall meet the requirements of the present document with the ra

The method of measurement shall be in accordance to IEC 60835-2-2 3. 6.1 Radiation Pattern Envelope (RPE) RPE(s) for each class are included, in order to present the maximum flexibility to administrations for o
