Each year, the highest costs in Telecom network shelters and cabinets are not related to personnel or construction, but to energy consumption. The highest proportion of energy costs derive from the energy consumption of electronics cooling units, which run around the clock to ensure well-balanced running temperatures for the enclosed electronic equipment. Technologies designed to reduce energy emissions...
Increasing IT demand has put pressure on the data center, prompting managers and operators to rethink their approach in responding to business needs. Today, IT, telecommunications and data center managers are recognizing the value of integration, both in their IT and communication stacks and in the facilities that support them. Designing, configuring and fabricating data center or telecommunication...
Intermediate Bus Architectures have been popular in the telecom industry for their ability to easily accommodate a wide variety of loads from the telecom industry's common 36–60V distribution voltage range [1]. A key performance metric of telecom power systems is based on the performance of the bus converter used to enable this architecture. While point-of-load converter performance is mostly driven...
This paper looks at multiple energy sources now available at the cell site, as well as design and management complexities that have risen as a result. The goal of this paper is to outline design considerations for each alternative energy source, such as technologies, logistics, setup and operation. By showing these considerations, decision-makers can refine objectives for deployment and operation,...
Demand for reliable, efficient mobile network services is increasing, as customers seek for more value-added services (VAS) from telecom operators. However, many operators still suffer from network outages as they do not have solutions in place that will detect and alert them of a problem even before it escalates. Network outages can be prevented through a comprehensive, intelligent monitoring system...
A green base station with a cylindrical flexible photovoltaic (PV) module mounted to a telecommunication pole is developed. The present paper proposes a method for calculating the power output of the cylindrical flexible PV module mounted to a telecommunication pole and describes the effects of the setting position of the PV module and height to diameter ratio of the pole on its power output taking...
The amount of energy consumed by data centers and telecom buildings is increasing annually due to the buildup and high-density arrangement of ICT equipment, which is needed to handle the rapid rise in traffic brought on by the spread of smartphones and advances in the Internet usage environment. At the same time, services that use ICT equipment are expected to provide high levels of reliability and...
Site infrastructure sharing is the trend of future base station construction. Telecom infrastructure operators require for smooth upgrading and low TCO when sharing sites power supply, spaces and operation management. This paper introduces a new integrated hybrid power supply system suitable for the site sharing requirements. It perfectly combines many functions together, such as energy generation,...
This paper presents a novel control scheme to control the flow of active and reactive power through a single-phase bi-directional AC/DC converters used for telecom backup systems. The proposed controller enables the telecom facilities to control the power flow in both directions from grid to telecom and telecom to grid. In this paper the fuel cell system coupled with ultra-capacitors has been used...
Telecommunications is a rapidly growing field in global technology and it has a significant social, cultural, and economic impact on modern society. As such, ensuring reliability of these systems should be highly prioritized and involve sophisticated standards. Due to the highly sensitive nature of Telecom loads, it is vital that failure of the utility power be detected quickly. In this paper, Slip...
The communication infrastructure is facing an increasing demand for higher bandwidth with larger coverage, both for fixed line xDSL networks and for wireless equipment. Such expansions in bandwidth and coverage introduce higher demand for power at an increasing number of sites. This paper presents and discusses a proposal for how to meet the increasing bandwidth demand with a remote power concept...
Efficiency and power density are the two most important index of the telecom rectifier development. During recent years, the efficiency of the telecom rectifier is pushed from 92% to 96% and now 98%, this paper however explores the design considerations of super high density (100W/inch3) telecom rectifiers in concert with high efficiency requirements (96%). Specifically, the design considerations...
This paper is based on the current situation of Chinese telecommunications network infrastructure, propose the technical solutions of power expansion, tenants expansion, tenants management, battery expansion and battery hybrid use management in the sharing and co-construction power site, the management methods of independent charged, independent discharging and hybrid use for different batteries and...
A new power supply topology is proposed for using various types of power supply systems together in data centers and telecom buildings. In this topology, the power supply chain from the building power receiving point to the IC chips in the ICT equipment is organized into blocks to simplify the number of DC bus conversion steps. Two types of voltage for the DC bus are proposed; 380 V and 48 V. This...
Interest and adoption of 400V DC power has been growing over the past decade. After many years of studies and trials, commercial implementation of 400V DC power in production telecommunications and data center sites is becoming a reality. This adoption is driven by multiple motivators, depending on the site-specific application and layout. This paper will present case studies of the implementation...
Line powering is a means of energizing remote equipment, from a centralized location, over the outside plant (OSP) telecom copper twisted-pair cable. It has been used for decades in telecom networks for various applications such as T-1 repeater powering, HDSL remote unit powering and DSLAM powering. Currently, line powering is being deployed for several telecommunication applications such as FTTN,...
