Nujira raises funds for its smartphone power reduction technology

UK-based Nujira, which develops technology to reduce power consumption in smartphone transmitters, has landed a further £10m of funding. The investment round will help Nujira’s achieve its ambition of installing its Coolteq wideband Envelope Tracking technology into 800 million energy efficient 3G and 4G devices by 2016.

Nujira supplies ultra-high efficiency RF Power Amplifier (PA) technology for the mobile infrastructure and handset and broadcasting markets. Half of base station power is used by the PA and up to 85% of that power is wasted as heat. Nujira’s technology can significantly improve the efficiency of the PA, reducing radio network power consumption by up to 50% and reducing typical network power costs by $20m per annum. That could mean a reduction of 20 million tonnes of CO2 emissions globally every year.

Nujira's technology is currently being trialled by twelve major mobile infrastructure vendors and two broadcast infrastructure vendors. The company is selling the technology to manufacturers of 3G and 4G base stations, broadcast transmitters and mobile device OEMs and semiconductor companies. The company believes there is a total addressable market of over $1bn by 2013.


Based on the information provided on what the technology can do and the savings it can make, it’s no surprise that Nujira has raised the money. (The investment was led by a new investor, Climate Change Capital Private Equity and supported by existing investors Amadeus, NES Partners and Environmental Technologies Fund).

The telecoms sector is, in any case, actively looking to significantly reduce its emissions (see info on GreenTouch and LightRadio initiatives), so Nujira’s green ICT offering looks to be in the right place at the right time.
