The United Nations has published its 2016 Sustainable Development Goals, which focus on building sustainable infrastructure and sustainable consumption and production patterns. This will force enterprises in all sectors of economy to refocus on energy. According to an IEEE study, telecommunications consumes more than one percent of world's total energy consumption, which is roughly equivalent to all of Saudi Arabia's energy consumption.
Electricity costs, along with rent and equipment/depreciation, are top three operating costs of operating a network (whether it's a wireless carrier, a data center host, or a broadband service provider), so it's included in every carrier's budget . key role in Let's look at three areas that can have biggest impact on service providers.
Reduce network power consumption
There are five key areas where operators can reduce power consumption in their radio access networks (operations):
Energy consumption of equipment
DC losses
RF Loss
RF Transmission Efficiency
User Distance
Device power consumption is set at deployment time, but affects operating costs over life of product. As power amplifiers and various digital processing components become more efficient, they consume less power and reduce cooling costs, which in itself is a huge customer benefit.
Resistive direct current (DC) losses occur in mast between base and remote radio head (RRH). With a large distance between mast and RRH, current losses in cable can be significant.
RF losses have occurred in past when active components (amplifiers) directly impacted system. Duplexers, cables, combiners, and antennas reduce amount of RF energy that is actually transmitted to user.
The effectiveness of RF transmission depends on radiation pattern of antenna as well as its directivity. In both settings and modes, antenna plays a very important role in speed and power efficiency of network. Higher demands on active part of system, lean mode and inaccurate alignment results requiring more power.
User distance simply means that closer user is to transmission point, less power is required to transmit to user and infrastructure. Whether indoors or on subway, smaller cells are physically located closer to user, reducing power consumption per cell.
Create a connected and efficient building network
In future, several separate networks will be combined into one system. Other networkThe data communications used to control everything from air conditioning to entry systems will be combined with traditional Ethernet networks, wired and wireless connections. Data networks are not only area that could change. Over past 100 years, electrical grid has undergone some changes, but is also beginning to join grid revolution.
2003 Power over Ethernet (PoE) compatible mobile DC power supply delivering 15W of power. It has been increased to 25W and is planned to be increased to 90W. Although transferring power at lower DC voltage and smaller diameter wires reduces transport efficiency, it improves efficiency, conversion, and control, and greatly reduces cost and speed of deploying devices at edge.
When using high power, draft IEEE p802.3bt standard supports power scaling between switches and powered devices, but requires high quality wiring. The ability to regulate and turn off power is environmentally friendly as it reduces overall power consumption.
Power on remote device
Broadband service providers must deploy remote equipment, but this is difficult when it comes to location and power at edge. Network engineers plan required locations, but without local power, placing alternative locations is cost-effective. Deploying hybrid cable, fiber optic cable, and low-voltage cable powered from one location is a great option for those looking for local AC power. This integrated solution significantly reduces planning and deployment time. This enables deployment of fiber demarcation points, metro cells, and other outdoor peripherals such as Wi-Fi and security cameras.
With growing need to transfer more data for less money, network operators will continue to focus on improving efficiency of their networks while keeping energy efficiency in mind. Is your network performing well enough?
