Sustainable power-feeding solutions for 5G networks
|Publication Date:||1 December 2019|
This Recommendation defines power-feeding solutions for 5G, converged wireless and wireline access equipment and networks, while taking into consideration their enhanced requirements on service availability and reliability, new deployment scenarios, together with the environmental impact of the proposed solutions.
Also defined are the minimum requirements of different solutions, including power-feeding structures, components, backup, safety requirements and environmental conditions.
This Recommendation is applicable to the powering of both mobile and fixed access network elements, in particular to equipment with similar configurations and needs.
The future development of 5G networks will create a new scenario in which the density of radio cells will increase considerably, together with the increase of wireline network equipment, that are going to be installed in the vicinity of the users; thereby, this creates the need to define new solutions for powering that will be environmentally friendly, sustainable, dependable, smart and visible remotely.
The -48 VDC, up to 400 VDC local and remote power solutions defined respectively in [ETSI EN 300 132-2], [b-ETSI EN 302 099] and [ITU-T L.1200] will be considered as the Standards in force for power facilities, together with [IEEE 802.3] that concerns power over Ethernet (PoE).
