Does a hybrid network consume more energy than a full-digital network?

The energy consumption of the network gets increases as the density of small cells rises. Certain findings as indicated above suggests that hybrid architectures in massive MIMO systems have much higher achievable EE, although their SE is lower than full-digital architectures.

What is a hybrid solar PV / BG energy-trading system?

A hybrid solar PV / BG energy-trading system between grid supply and BSs is introduced to resolve the utility grid’s power shortage, increase energy self-reliance, and reduce costs.

Does a hybrid approach improve EE and SE performance in small cells?

For small cells in UDN, a hybrid approach optimizing both EE and SE is required with the constraints of high data rate and interference thresholds. It was observed that, with a slight decline in SE performance, the EE may be greatly enhanced.

What is hybrid solar PV / wt / BG?

Given the geographical position, the hybrid solar PV / WT / BG system along with appropriate energy storage devices is an effective solution for developing green cellular connectivity. It offers a potential solution for bridging the gap between high data rates and long idle times in the 5G mobile network .

How can cellular network operators shift towards green practices?

The green communication initiative focuses primarily on improving EE, reducing costs such as CAPEX and OPEX, and eliminating extra BSs’ emissions to ensure their future evolution. Therefore, the cellular network operators use the following main approaches a try to shift toward green practices as shown in Fig. 4.

How BS affect the energy consumption of a cellular network?

To contribute to the expansion of mobile traffic, a large number of BS are required. In a regular cellular network, the BSs consume more than half of the total energy, therefore their increased numbers have a significant influence on the overall energy consumption.
