Taiwan Mobile has always engaged in self-improvement to become a world-class company. To pursue the goal, a proposal to field a new generation of telecommunication technology and cell sites, base stations was implemented to save power as part of the company's efforts to achieve sustainability.
On March 1, Taiwan Mobile announced its collaboration with Nokia at MWC. Witnessed by Taiwan Mobile Chairman Daniel Tsai and Nokia President and Chief Executive Officer Pekka Lundmark, Taiwan Mobile President Jaime Lin and Markus Borchert, President of Nokia Greater China, signed an "ESG & 5G MOU."
Following its merger with Taiwan Star, Taiwan Mobile will use Nokia 5G cell tower solutions to integrate "New Taiwan Mobile's" disintegrated 60MHz and 40MHz in the 3500MHz bandwidth, employing its 5G "NR CA" technology to provide the highest bandwidth in 100 Hz in its 5G network and improve internet efficiency, without the need to purchase another set of network equipment.
This energy-saving collaboration with Nokia will see Taiwan Mobile save 100-200 million kWh of electricity per year, creating a win-win situation for both users and environment.
"The collaboration between Taiwan Mobile and Nokia has been going on for more than 20 years since the start of the 2G era, making Nokia one of Taiwan Mobile's most important suppliers," Tsai said.
"Apart from both being longtime partners in building 5G network infrastructure, the two parties now need to jointly combat challenges arising from climate change. Based on the "ESG & 5G MOU" clinched between both, the two companies will work to reduce carbon emissions in the 5G era, Tsai said.
As cell sites, base stations account for around 90 percent of energy consumption of the telecommunication industry, Taiwan Mobile will collaborate with Nokia to slash power consumption by increasing the use of green energy at its cell sites, base stations and introducing Nokia technologies to sharpen their efficiency and lower energy waste to strive for the sustainability of the earth, Tsai said.
Markus Borchert, President of Nokia Greater China, said, “We are thrilled to partner with Taiwan Mobile to tackle one of the principal challenges of our generation, namely the environmental sustainability of our planet. In a move that would make a zero-emission network a reality, we are committed to working collaboratively with Taiwan Mobile to help achieve its ESG goals by deploying our energy-efficient AirScale portfolio that will deliver a greener network, deliver better performance, and reduce the environmental impact.”
With the successful merger between Taiwan Mobile and Taiwan Star, the "ESG & 5G MOU" will allow Taiwan Mobile to use Nokia's cell tower solutions to integrate the hardware on "New Taiwan Mobile's" disintegrated 60MHz and 40MHz network in the 3500MHz bandwidth, and the use of the "NR CA" technology will provide the highest bandwidth in 100MHz services to save the trouble for Taiwan Mobile to build and maintain two independent networks and electrical systems.
At the same time, Nokia will aid in reusing components from this integrated hardware, allowing the recycling of telecommunication equipment while slashing the level of waste from building new telecommunication equipment. With the help of Nokia, Taiwan Mobile built over 3,000 5G NR CA cell sites, base stations of the 700MHz long range wireless with 3500MHz high bandwidth frequency bands in 2022, which in turn has improved indoor 5G coverage and quality and has increased more than 50 percent in 5G data transfers by 5G users on an annual basis.
The revamp of spectrum resources by Taiwan Mobile will avoid the maintenance of a set of 3G voice network and shut down thousands of overlapping 4G cell sites, base stations. In conjunction with Taiwan Mobile's smart power saving system, 74 million kWh of electricity will be saved per year.
Judged by a long-term calculation of potential power saved, an annual saving of up to 100-200 million kWh of electricity can be achieved, compared with calculation based on the infrastructure operated independently by the two companies. At the same time, Taiwan Mobile's use of Nokia software to save energy further saved 5.3 million kWh of electricity in 2022.
Based on the foundation, the recently inked MOU will further cement the collaboration between both companies, which was expected to help save an additional 4 million kWh of electricity in 2023- an equivalent of around 9 million kWh of energy saved in nearly 2 years.
That also equals to carbon emission reductions totaling 4,581 metric tones to be discharged by 13,000 gasoline motorcycles off the streets for a whole year, pushing Taiwan to move toward the goal of zero emission by 2050.
In order to mitigate the impact of building new cell sites, base stations on city skyline, Nokia will also develop a package of integrated antennas that fits "New Taiwan Mobile's" standard by integrating the specifications of "New Taiwan Mobile's" passive antennas' 700MHz, 900MHz, 1800MHz, 2100MHz and 2600MHz with active antennas of 3500MHz to lower the number of antennas and reduce the impact of cell sites, base stations on landscape.
Taiwan Mobile's close cooperation with Nokia does not only seek to step up the development of the mobile telecommunication industry, but it also aims to upgrade telecommunication service quality, energy usage efficiency, internet transformation and industry digitization, helping different industries to achieve sustainability by smartly using mobile telecommunication technologies.
Based on the research piloted by "Nokia Bell Labs," Nokia is set to help Taiwan Mobile introduce its 5G Advance technologies to help Taiwanese industries upgrade their technologies and cut their energy consumption as means of contributing to sustainability.
