Towards Efficient, Reliable, and Cost-Effective Power Supply
Thus, telecom sites must be accurately re-designed, starting from the power supply units (PSUs), which will be replaced by new ones with higher output power and typically higher
Xie Cun, director of the information and communication development department at the ministry, said that Chinese operators have already deployed more than 1.15 million 5G base stations, accounting for more than 70% of the global total, and 5G network coverage has been achieved in urban areas of all prefecture-level cities.
Each nation has a different 5G strategy. For 5G, China uses 3.5GHz as the frequency. Then, a 5G base station resembles a 4G system, but it's on a much larger scale. For sub-6GHz in 5G, let's say you have a macro base station. The power levels at the antenna range from 40 watts, 80 watts or 100 watts.
From the trends and challenges mentioned above, we can derive three key general requirements for the 5G infrastructure: • High efficiency. Achieving high efficiency is the best way to reduce heat dissipation (due to high power consumption compared to 4G) and operational expenses (OPEX). • Re-use of existing infrastructure.
The 5G spectrum has been released in several countries worldwide and already in commercial use. 5G is accelerating and promises to change our lives thanks to large bandwidth, massive connection, and ultra-low latency. On top of this network evolution, we need to consider the advancements in the so-called mobile edge computing (MEC) area as well.
