Why are solar and wind plants growing in Mexico?
Historical growth of solar and wind installed capacity in Mexico. The rapid growth in the installation of photovoltaic and wind generation plants is because of the Energy Reform that was approved in 2013 ( Alpizar-Castro and Rodríguez-Monroy, 2016), and the large number of renewable resources that the country has for the generation of electricity.

What is a 5G base station?
Base Station Base Station (BS) is a key component of the 5G Radio Access Network (RAN) architecture that serves as an access point for wireless connections between user equipment (UE) and the network. It consists of a radio unit and an antenna system that transmits and receives signals to and from the UE.
What are the components of a 5G core network?
The key components of a 5G core network are seen here: User Equipment (UE): 5G cellular devices, such as smartphones, connect via the 5G New Radio Access Network to the 5G core and then to the internet. Radio Access Network (RAN): Coordinate network resources across wireless devices.
What are base stations in 4G LTE networks called?
The base stations in 4G LTE networks are called either evolved Node B or eNodeB. You'll find that eNodeB is usually abbreviated as eNB in 5G network architecture diagrams, and gNodeB as gNB. It helps to keep mind that a base station called eNB is for 4G, and gNB is for 5G.
What are the advantages of a 5G base station?
Massive MIMO: The use of a large number of antennas allows the base station to serve multiple users simultaneously by forming multiple beams and spatially multiplexing signals. Modulation Techniques: 5G base stations support advanced modulation schemes, such as 256-QAM (Quadrature Amplitude Modulation), to achieve higher data rates.

How do base stations reduce energy consumption?
Energy consumption is a main part of network operational expense (OPEX), and base stations work as the main energy consumption equipment in the radio access network (RAN). In order to achieve RAN energy efficiency (EE), switching off cells is a strategy to reduce the energy consumption of networks during off-peak conditions.

Why does network sensitivity affect the energy consumption of base stations?
In addition, the high sensitivity of the existing policies to network conditions during the period when the network load is relatively smooth may lead to unnecessary and frequent switching of the sleep mode of the base stations, thus adding non-negligible additional energy consumption.
