Huawei has developed a new power-efficient innovations that will boost energy savings and enables Telecommunication Operators (Telcos) to build networks that are extraordinarily efficient.
According to totaltele.com, President of Huawei Antenna Business Unit Eric Zhao said the improvement of antenna efficiency will reduce the loss of energy during transmission.
“One of the biggest focus areas for telcos is energy efficiency. In the past decade the industry focused on gains from shrinking dimensions but neglected efficiency.
“Now we must place emphasis on efficacy as efficient antenna will contribute to a highly efficient network,” says Eric Zhao, President of Huawei Antenna Business Unit.
“If we can improve antenna efficiency, we can reduce the loss of energy during transmission, and that’s going to save energy consumption,” Eric adds.
Huawei says that its highly energy-efficient antenna with Signal Direct Injection Feeding (SDIF) technology helps telcos maximise energy saving while improving coverage. As a result, they can increase coverage and save energy.
The numerous cables and independent components inside an antenna are replaced by SDIF technology. Further, the traditional wires are replaced by metal striplines and the input and output are directly connected by metal striplines. As a result, there is no loss because the structure is directly connected.
Huawei’s unique SDIF technology has been designed for all antenna scenarios, and the company says that the antenna series is designed to meet the band- and region-specific configuration requirements, helping telcos get about a 20% increase in the energy efficiency of all bands.
Eric further said that antenna innovation shall move towards a more comprehensive aspect. We can call it generalised antenna efficiency, it includes:
RF efficiency, reduce the internal energy loss in antennas, reduce the waste of energy into heat and convert more energy into electromagnetic waves for network coverage.
Coverage efficiency means project more energy into the target area. This maximises the signal strength of the area where coverage is required and reduces the interference of the location where coverage is not required.
For example, based on Huawei’s latest Meta Lens technology, by managing antenna pattern to ensure power is concentrated in the appropriate directions, operators will get better network performance from high coverage efficiency.
And Beamforming efficiency, means enables antenna focusing more energy to user device which need date transmission, and reduces interference to other user devices.
This relies on high-precision hardware design to provide phase consistency between multiple arrays. In this way, users can obtain better service experience and network capacity is improved.
RF efficiency is a research field in the industry today and generalised antenna efficiency is the next research direction. Generalised antenna efficiency improvement will further help operators improve network energy efficiency and performance.
