This standard starts with the assumption that the energy consumption of the access network is dominating the energy consumption of other subsystems of the wireless telecom networks and defines the measurement method for the evaluation of base station power consumption and energy consumption.
Furthermore, the base stations dominate the energy consumption of the radio access network. Therefore, it is reasonable to focus on the power consumption of the base stations first, while other aspects such as virtualization of compute in the 5G core or the energy consumption of user equipment should be considered at a later stage.
Is there a direct relationship between base station traffic load and power consumption?
The real data in terms of the power consumption and traffic load have been obtained from continuous measurements performed on a fully operated base station site. Measurements show the existence of a direct relationship between base station traffic load and power consumption.
The largest energy consumer in the BS is the power amplifier, which has a share of around 65% of the total energy consumption . Of the other base station elements, significant energy consumers are: air conditioning (17.5%), digital signal processing (10%) and AC/DC conversion elements (7.5%) .

The 28th Mountain Division of the Army of the Republic of Bosnia and Herzegovina (ARBiH) that remained in the enclave was neither well-organized nor well-equipped. A firm command structure and communications system was lacking and some soldiers carried old hunting rifles. . The NATO intervention in Bosnia and Herzegovina was a series of actions undertaken by NATO whose stated aim was to establish long-term peace during and after the Bosnian War. [23] NATO's intervention began as largely political and symbolic, but gradually expanded to include large-scale air. . Under his regime, Tito had outlawed nationalism, and the six republics of Yugoslavia—Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia—were ruled under the slogan “Brotherhood and Unity. Therefore, are not evidence of a dispute.

Within the Membership Action Plan, the country's cooperation with NATO is structured through the Bosnia and Herzegovina Reform Programme, which outlines the reforms the government intends to undertake and facilitates the provision of support by NATO toward these efforts.
On October 9, 1992, the Security Council passed Resolution 781, establishing a no-fly zone over Bosnia-Herzegovina. In response, on October 16, NATO expanded its mission in the area to include Operation Sky Monitor, which monitored Bosnian airspace for flights from the Federal Republic of Yugoslavia.
A series of grave developments led NATO to intervene in Bosnia in 1995, including war crimes, the genocidal fall of Srebrenica, the taking of UN hostages by Bosnian Serb forces, and breaches of the Geneva Conventions. A NATO military operation was conducted in Bosnia, a country not a member of the alliance.
The unpopularity of NATO among Bosnian Serbs, as a result of its involvement in the 1992–1995 war and its airstrikes against Serbia in 1999 (especially during the Kosovo War of 1999), have contributed to Republika Srpska's continued obstruction of Bosnia's NATO integration progress.
