Improve energy efficiency without compromising network performance
Increasing mobile network usage is driving a need to deploy more capacity, creating a sustainability challenge for service providers like Rogers Communications. Now, utilizing Ericsson solutions which reduce carbon emissions and provide cost savings while improving network energy performance, the company is saving 25 GWh of power annually.
Background
Rogers Communications is a leading Canadian technology and media company that operates Canada’s largest and most reliable 5G networks. It connects Canadians, each and every day, to a world of possibilities and moments that matter most in their lives. According to the GSMA, network energy consumption is one of the highest operating costs. Just like operators worldwide, Rogers Communications has been seeing its energy usage rise. Since 2019 Rogers has been focusing on various innovations to improve the energy efficiency of its network, proactively working towards delivering a 25 percent reduction in their carbon emissions by 2025.
The challenge
-
Increasing mobile network usage is driving a need to deploy more capacity, creating a sustainability challenge for service providers.
-
Since 2015, Rogers has experienced a 500 percent increase in total traffic, driving up absolute energy consumption considerably despite a reduction in total energy usage per petabyte of data.
The solution
- Micro Sleep Tx (MSTx) automatically switches off radio power amplifiers, saving energy during low traffic.
- Low Energy Scheduler Solution (LESS) reschedules downlink transmissions for non-critical data. Time-sensitive transfers are excluded so quality of service is never compromised.
- Automatically reducing power consumption during low-traffic hours, MIMO Sleep Mode (MSM) reconfigures based on traffic load.
- Cell Sleep Mode (CSM) turns off the power amplifier for a capacity cell when the total traffic is below a set threshold.
The result
Ericsson saved Rogers 25 GWh of power annually, which equates to an estimated reduction of 3,000 metric tonnes of CO2 emissions.
Ericsson’s innovative Radio Access Networks (RAN) energy-saving software enables service providers to decrease power consumption while preparing their networks for 5G consumer and business demand.
