Power Supply Solutions for Wireless Base Stations Applications


Every year, our reliance on always-on wireless technology grows. We expect to be able to place a call or surf the Internet with our smartphones at any time and under any circumstances. We take for granted the importance of powering network stations to provide us with these services.


In fact, the electrical infrastructure that powers the telecommunications networks still struggles to keep up with the explosive growth in demand and the user's expectations of 24/7 availability. Power supply connection represents a real challenge for telecommunications companies, especially when their performance becomes sub-par or is subject to inevitable outages.


The telecommunications infrastructure and equipment are becoming increasingly more sophisticated, with even more advanced mobile communications networks, mobile terminals, and wireless base stations. In particular, as wireless technology evolves, so does the need for increasingly more reliable power supplies.


In this article, we will examine some of the components of wireless base stations, their power requirements, and a solution to some of these challenges.


Power Supply Solutions for Wireless Base Stations

Telecommunications Systems Overview

Telecommunications systems deliver many of the communications services we rely on daily, including the Internet, high-speed data, and mobile phone communication. In particular, wireless technology plays a major role in modern communication systems. As wireless network infrastructures evolve, new and more complex powering architectures have also emerged, driving the need for more reliable and stable power supplies.


Power supplies can be employed in each of the three systems that compose wireless base stations. These three systems are known as the environmental monitoring system, the data communication system, and the power supply system. Each of these systems is in turn divided into smaller sections and components.


The Components of a Wireless Base System

Below we will review each of these three systems, their components, and their respective roles in a wireless base station.


Components of a Wireless Base System

● Power Supply System

Even the most advanced wireless network grid can fail from time to time. No type of equipment is immune to the possibility of power interruptions that may last for hours or days. In case of a power outage, shutting down a wireless base station is not an option. For this reason, battery backups and generators are installed in a wireless base station’s power supply system to allow continuous operation under all circumstances.


In a wireless base station, the power supply system includes generators, backup batteries, and circuit breakers.

● Environmental Monitoring System

The environmental monitoring system is used for real-time monitoring of the environment in which the wireless base station is operating. As the name suggests, it is tasked with monitoring the temperature, humidity levels, as well as water leakage. This system helps to prevent hardware damage to wireless data centers and network closets through critical condition alerts.


The environmental monitoring system consists of a series of working base stations, such as entrance guard systems, ventilation systems, integrated dynamic environment monitoring systems, intelligent air conditioning controllers, and more.


● Data Communication System

In a wireless network infrastructure, data communication refers to the exchange of data between a source and a receiver through a medium such as wire cables. In a wireless base station, the data communication system ensures the transmission of data that is at the core of the wireless network.


The data communication system of a wireless base station comprises antennas, BBUs (Baseband Units), RRUs (Radio access networks), and AAU (Active antenna units).


The Challenges of Powering Wireless Base Stations

Wireless networks are subject to intense power demands and extreme space constraints, making it more challenging to supply the necessary power at all times and without interruptions.


Power solutions for wireless networks applications must have a wide voltage range, high power density, compact size, excellent reliability, high efficiency, and low no-load power consumption.  When designing an electrical circuit for wireless networks, engineers are faced with the challenges of finding reliable power solutions as well as limiting the costs of the whole project.


Power modules play a key role in the environmental management system, where they can support real-time monitoring of the equipment's status and detect any anomalies.


Luckily, MORNSUN has a series of power solutions designed to provide state-of-the-art reliability while also curbing any unnecessary costs related to their installation, application, and maintenance of wireless base stations and 5G base stations.

MORNSUN's Power Supply Solutions

From the widespread 4G to the latest 5G technology, wireless networks drive our modern communications, promote the sharing of information, and at times even literally support entire businesses' operations. For this reason, the power supplies used to power them need to support their constant and stable performance.


MORNSUN has designed entire collections of power supplies and related electrical components, which are all known in the industry for their high reliability and quality. In particular, MORNSUN can provide specific power supply solutions for optical communication and 5G base stations applications.


In particular, MORNSUN's VCB/VCF series of isolated 3-400W DC/DC converters meet the demanding power requirements of wireless networks, which support 36VDC to 75VDC input. These converters are already widespread across a wide range of telecommunications equipment. They are extremely reliable and provide very low power consumption.


These DC/DC converters are known for their certified quality, as they meet the CISPR32/EN55032 CLASS A (without extra components) standards. These DC/DC converters are also IEC 60950, UL60950, and EN60950 approved. They are also highly efficient (up to 88%) and highly secure, as they can provide input under-voltage protection, output short circuit, over-current, and over-voltage protection.
