The main advantages with such technologies are: • Lower cost of ownership (equipment count, tower footprint). • Easier alignment during installation. • Lower visual impact.... |
8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 8.1 Architecture | In order to separate TX and RX directions in traditional radio links the two traditional approaches adopted are separation in frequency (FDD) or in time (TDD). The largely dominant solution in traditional MW links is FDD, implemented by means of duplexer filters which allows the use of one single antenna by providing t... |
8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 8.2 DREAM project | In the framework of the Horizon 2020, DREAM project [i.6] aims to demonstrate the feasibility of transceiver operating in D-band (130 - 174,8 GHz) with an active phased antenna array for beam steering functionality. The DREAM project is based on a power efficient silicon based BiCMOS transceiver analogue front end for ... |
8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 8.3 Flexible FDD (fFDD) | A system architecture that employs two separated antennas for TX and RX paths allows avoiding the use of a duplex filter with a fixed separation in frequency, provided that sufficient isolation is achieved between the two paths. On this base a flexible scheme for spectrum management named flexible FDD (fFDD) is feasibl... |
8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 8.4 Full duplex | A Full Duplex (FD) system is one in which the transmission and reception in both directions of a link can be done at the same frequency and time. The separation between the two communication directions can be made based on dimensions other than time and frequency: • space separation (e.g. separated TX and RX antennas);... |
8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 9.1 Systems with equivalent virtual antenna connector | Even if the antenna is non-detachable from the equipment, there are cases in which an equivalent antenna connector can be defined, by measuring the EIRP and going back to the transmitted power by means of the antenna gain declared by the manufacturer and/or calculated by means of equations. In general systems with one ... |
8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 9.2 Systems without equivalent virtual antenna connector | There are cases in which an antenna connector cannot be defined, not even in a virtual way. Systems providing multiple beams and dynamic beamforming are examples of this category. In this kind of systems both the requirements and the conformance testing are to be defined in a radiated way. Proper work is ongoing within... |

8eccd43d24b0ca4bc02ef53dcb5ed5af | 104 139 | 11 Conclusions | The traditional antenna used in MW radio links for Fixed Service is a passive detachable one, where system requirements are defined and verified at the antenna connector; the antenna is characterized by parameters like gain, bandwidth and loss and represented by its radiation pattern in space. Harmonised standards have... |
