Sparring Partners | Energy efficiency in private networks
A conversation with Simon Fletcher, Small Cell Forum
Most mobile operators have a strong public commitment to meet net-zero targets and achieve higher energy efficiency. What is happening in private networks run by enterprises, real estate managers, or public entities? How energy efficient are private networks? How should we assess their energy efficiency? How does it compare to 4G and 5G public networks?
Simon Fletcher, CSO at the Small Cell Forum, joined me in a discussion on energy efficiency and sustainability in private networks. It is a topic that has not yet attracted the attention it deserves, in light of the great growth potential of private networks.
We explored what we think are the most intriguing dimensions affecting energy efficiency in private indoor networks:
