Israeli startup eVolution creates a power-saver mode for mobile networks

Tel Aviv-based eVolution Networks revealed its first customer this week, announcing that pan-Caribbean mobile operator Digicel is adopting its Smart Energy Solution (SES), a set of technologies that allows a carrier to power down its towers when not in use.
It sounds like a simple idea, but it’s not an easy one to implement. Mobile networks are designed to deliver their full capacity at a moment’s notice in order to handle the unpredictable patterns of the cellphone-wielding public. Consequently most base stations remain at full power whether it’s rush hour or the wee hours of the morning.
eVolution’s technology constantly monitors, analyzing its radio coverage characteristics as well as daily traffic patterns. Based on that information it decides which base stations in which places can safely be powered down at night or during other off-peak hours without sacrificing coverage. As traffic patterns change, SES changes the mix of cells staying online and off.
