Environmental Engineering (EE); Sustainable power feeding solutions for 5G network
|Publication Date:||1 December 2020|
The present document defines power feeding solutions for 5G, converged wireless and wireline access equipment and network, taking into consideration their enhanced requirements on service availability and reliability, the new deployment scenarios, together with the environmental impact of the proposed solutions.
The minimum requirements of different solutions including power feeding structures, components, backup, safety requirements, environmental conditions are also defined.
The present document is applicable to powering of both mobile and fixed access network elements, in particular on equipment that have 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 to the users, thereby creating the need to define new solutions for powering that will be environmentally friendly, sustainable, dependable, smart and visible remotely.
The -48 V DC, up to 400 V DC local and remote power solutions defined respectively in ETSI EN 300 132-2 , ETSI EN 302 099 [i.10] and ETSI EN 300 132-3-1  or Recommendation ITU-T L.1200 [i.13] will be considered as the standards in force for power facilities, together with IEEE 802.3TM [i.18] (PoE).
