Carbon Trust Investments has invested £1.45 million in network optimisation company Arieso, joining existing investors Oxford Capital Partners, ADD Partners and Qualcomm Ventures.
Rachael Nutter of CT Investment Partners said: "Energy consumption in mobile phone base stations is a significant proportion of the opex of mobile operators, as high as 50% in the most extreme cases. Arieso's technology tackles this whilst improving service levels. We are excited about the potential for rapid scale-up of this technology on the back of a number of highly successful demonstrations"
Shirin Dehghan, CEO and co-founder of Arieso said: "Arieso has leading edge technology demonstrating dramatic service and cost improvements with a number of the world's largest operators. We are delighted to have Carbon Trust Investments joining our existing investors. This investment will allow us to ramp up our team and take advantage of our recent success in the field to deliver full-scale roll-outs."
Arieso's enterprise product GEO monitors and geo-locates calls made in a wireless network, allowing network operators to understand the service experience in real-time, enabling them to identify hotspots where infill network capacity is required, or where antennae positioning could be optimised to improve service and reduce power, reducing both capex and opex.
In a trial for US tier-1, Arieso claimed its software enabled 48% power reduction, 75% increase in data throughput and 64% fewer sites requiring additional 50W carriers, which are installed to boost wireless signals particularly in urban areas.
To get the data Arieso provides, the current alternative for mobile network operators driving vehicles to test service and strength of signal at different points.
