Concept of operating frequency of hybrid energy for communication base stations

4 FAQs about Concept of operating frequency of hybrid energy for communication base stations

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 the energy consumption index (ECI) of a cellular network?

Categorizations of green cellular network approaches Expanded visualization of mobile network architecture Brief description about components of the base station Energy Consumption Index (ECI)—It represents the efficiency of BS power utilization. The lower value of ECI means greater EE as mentioned in Eq. 6 below. Its unit is J/bit.

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.

Are hybrid MIMO systems better than full-digital architectures?

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. There should be an optimal value of Signal-to-noise ratio (SNR) and no. of antennas as mentioned in .
