Design of DC48V Communication Devices Power Consumption Metering Module AMC16L-DETT for Telecommunication Industries

Today's communications industry is naturally in the era of 5G. The number of 5G base stations across the country has reached an astonishing 2.733 million. However, most users do not have a deep understanding of 5G, and they do not have the new feeling of life when 4G was launched.

The high power consumption of 5G base stations is also one of the reasons why 5G communications are difficult to spread over a wide range. There are even rumors that 5G will be turned off at night because it consumes so much power, and then turned on again during the day. So is this statement true?

1. Rumors that 5G devices sleep at night

Although it is now claimed that the communication industry has entered the 5G era, a large number of communication mobile phones, communication equipment, etc. support 5G, and the construction of 5G base stations in every rural corner is complete, but there are not many occasions where 5G is actually used.

The operation of 5G base stations is also difficult to reach a stable level. Although the network speed has increased compared with 4G, the increase is very limited. Therefore, the so-called staff explained that the current 5G is facing the problem of high power consumption, so the 5G base station does not open all functions on a daily basis, but only controls the work at the lowest threshold.

Moreover, China Unicom staff previously claimed that China Unicom has implemented an intelligent startup device for 5G equipment, which can turn on the sleep mode during leisure time and wait until the usage is high before turning on the equipment, thereby achieving the best power saving effect.

This is also interpreted to mean that 5G devices will sleep at night, but in fact the sleep mode is not equal to the hibernation mode. Although the 5G device sleeps, it can still guarantee the basic use of the user, and only uses its own power according to the number of users. adjust.

So the speed of 5G is not much different from that of 4G, so why does the power consumption increase exponentially?

2. Why does 5G consume so much power?

As the two leading companies in the construction of 5G base stations in China, Huawei and ZTE have previously announced the power consumption data of 5G equipment. The results are about three times that of 4G equipment at full load. The reason why there is such a disparity in results is because the frequencies used by the two are completely different.

5G base stations use high power consumption and high radio frequency signals, which are used to process more signals from digital units and electromechanical units, and will also put greater pressure on the AU module. But at the same time, it can also bring users faster signal reception and response.

In the same way, if 5G signals are used, the power consumption of mobile phone users' devices will continue to increase, and high-frequency use will also lead to serious heat generation. Seriously, it may even affect the service life of the equipment.

3 Acrel Tower Base Station Energy Consumption Solutions

(1) This solution was designed for IoT online precise sub energy monitoring of the overall telecommunications tower base station.

(2) Normally, the power system of base station could be devided into AC part and DC part [-48Vdc]. And usually request a multi-channel metering regarding the different energy usage like  for different telecommunications service provider's base station communications equipment [DC side]. Or for either the mains supply, back-up generator, lighting, airconditioner of base station. [AC side] Thus, multi-channel DC or AC energy meter will be the key to solve such request.

(3) This solution was majorly for both cloud&local energy monitoring, different from Acrel local

energy monitoring solution which is designed for base station local energy monitoring by providing only hardware. In other hands, this solution could be also adapted to 3rd party IoT

energy monitoring system via API or SDK for data transferation
