In an effort to reduce energy consumption on its 4G network, EE has recently introduced new ‘cell sleep’ technology. This innovative solution allows specific 4G LTE carriers to enter a low-power mode during periods of decreased demand. By utilizing machine learning to analyze usage patterns at each site, EE can schedule these low-power periods in a way that minimizes disruption to service. If demand unexpectedly rises, the site can quickly return to full power within seconds. In instances of extremely low demand, such as late at night, sites can enter a ‘deep sleep’ mode to further conserve energy.
The implementation of this technology is expected to save up to 2 KWh per site daily, which amounts to an impressive 4.5 million KWh annually across EE’s network. Greg McCall, BT’s Chief Networks Officer, highlighted the potential for significant energy savings by aligning power usage with network demand. He acknowledged that implementing cell sleep technology at over 19,500 sites is a major step in managing the increase in data consumption.
The idea of adjusting a mobile site’s power consumption based on real-time demand is gaining traction in the industry. Advances in AI and machine learning have facilitated the adoption of these technologies. Ericsson has demonstrated its sleep mode technology with Deutsche Telekom, showcasing the growing interest and potential advantages of energy-efficient solutions.
EE’s move towards dynamic cell sleep technology not only enhances its network operations but also promotes more sustainable energy usage. This action sets a standard for other mobile operators to follow in terms of energy efficiency and environmental responsibility.
