Can telcos be innovative and green?

Must Read

In one way or another, most people across the globe are ‘addicted’ to online connections and experiences. Whether instantly streaming a movie or downloading a file to a laptop – the slightest delay in connectivity causes frustration.

As a result, consumers seek a network provider offering the most innovative products and services at an affordable price. However, the public is also becoming more environmentally conscious and some will avoid brands that don’t have strong green credentials.


This leaves the telco industry at an inflection point. Telcos need to continue to innovate to satisfy ‘the connected consumer’. However, they also need to be mindful of the considerable energy consumption they are responsible for and the knock-on effects to the bottom line this causes as energy prices skyrocket.

The consumption conundrum

I believe that service providers can continue to innovate while creating a greener, better telco industry.

Currently, the telco industry is one of the world’s largest energy consumers, which, according to the Future of Commerce, accounts for 4% of global consumption. This enormous power draw dramatically increases the industry’s carbon footprint. With rising energy prices, telco networks cannot afford to continue at this pace.

Fortunately, this isn’t a problem the industry is taking lying down. Telco energy use is reducing as we speak. In fact, three of Europe’s biggest telco operators, BT, Orange, and Telefonica, consumed less energy throughout 2021 than they did in 2016. Action is being taken.

Within telecommunications, the actual networks themselves are responsible for consuming the largest amount of energy. Most energy-saving initiatives are, therefore, focused on modernising these networks from end to end. Upgrading networks to 5G is a fantastic example of this, as it carries many energy-saving benefits while providing better experiences for consumers.

Modernise, prioritise, capitalise

I believe the overarching solution to reducing energy consumption is modernisation, prioritising operational efficiency and cost reduction —things the industry is already doing in varying degrees.

Orange’s recent activity serves as a perfect example. Between 2014 and 2018, Orange experienced enormous traffic increases, but it weathered the ‘data tsunami’ using a range of tactics, including taking advantage of new datacentre cooling technologies and, most importantly, upgrading to 5G and leveraging its ‘energy optimisation’ features.

Our role is to enable telcos to do more with less from end-to-end, increasing efficiency and reducing energy consumption and carbon emissions. In fact, through Core, RAN, and Edge solutions, we have doubled the spectrum efficiency of our customers, while halving RAN energy consumption.

But these vital carriers can continue furthering their own sustainability efforts without compromising on the needs of ‘connected consumers’. Here are three considerations:

  1. Turning to renewable energy sources

Carbon emissions are created from the smallest of tasks, like emailing or searching for something on the web. However, with 4.1 billion people connected to the internet, this small amount of Co2 quickly adds up.

As electricity prices increase, sourcing strategic sustainable energy is a must. Transitioning to a renewable energy supply will reduce costs and ease reliance on energy sources that are liable to price swings influenced by global events.

Once again, Orange is thinking this way and recently announced its plans to build a solar farm to increase access to renewable energy.

  1. Upgrading to 5G networks

Over the past ten years, we’ve witnessed many successful implementations of 5G for a range of telco clients like Vodafone and Telia. Upgrading to 5G networks enables telcos to provide better consumer connectivity while reducing network consumption. For example, 5G networks are software-defined, which allows for resources to be allocated efficiently, reducing energy consumption.

Thanks to 3rd Generation Partnership Projects (3GPP), a group of organisations that set the standards and specifications for 5G, these networks include energy-saving features. These mechanisms reduce consumption by switching off cells or functions within a network. An example of this is ‘cell switching’, which allows 5G devices to switch cells depending on signal strength and quality. We are developing solutions, such as our RIC (RAN Intelligent Controller), to further 3GPP’s 5G features.

5G networks also use edge computing, which reduces the amount of data that needs to be communicated over long distances. However, due to 5G’s speed and efficiency, data surges spur consumption at the edge of a network. We are developing edge solutions to move closer to where these services are consumed, to make networks more efficient. Building, running, managing, and connecting via edge-native applications will be critical for telcos to overcome their challenge and deliver innovation for consumers. For example, edge computing coupled with 5G has enabled VR and AR to improve rapidly – providing the ability to render an environment in real time. This has enhanced services across industries from healthcare to education, delivering better consumer outcomes.

We are also developing solutions, such as our RIC (RAN Intelligent Controller), which allows programmability of the RAN to reduce power consumption at certain times of the day to further 3GPP’s 5G features.

With built-in capabilities and a range of energy saving features, upgrading to 5G is non-negotiable for telcos looking to prioritise sustainability and innovation.

  1. Deploying cutting-edge virtualization

Numerous brilliant minds are engineering incredible solutions that boost innovation and sustainability. We are lucky enough to have many of these minds in our engineering teams. As a result, our innovations are helping customers reduce their environmental impact while improving a range of offerings.

Just think, virtualization technology is helping reduce impact on operations while boosting productivity. For telcos, virtualization can be most effective when reproducing a physical network, allowing applications to run virtually, facilitating increased efficiency, reduced operating costs, faster workloads, greater application performance, and higher server availability. If not already, telcos must integrate virtualization technology into their stack to increase sustainability and productivity.

A positive sustainable outlook

Modernising networks from end to end to keep pace with today’s consumer, while prioritising sustainability, is a challenge best met head-on. Once telcos turn towards one, or all the steps mentioned above, the industry’s sustainability outlook will quickly turn positive, and other sectors will follow suit.

The telco industry is doing an amazing job transforming its operations to create a better, greener industry. Despite skyrocketing energy prices and speculations of a recession, we aren’t seeing our telco customers cut investments into ingenuity and sustainability. Instead, we are witnessing a shift in the rationale for investments, where innovation and sustainability are now the top priority. Our vision is to enable telcos to build a more sustainable, equitable, and secure digital future for all.
