Helping radio networks
‘go green’
Modern radio and broadcast technologies such as WCDMA, WiMAX and DVB provide consumers with high bandwidth mobile connectivity, but at a cost - high network and handset power consumption, due to poor RF power amplifier (PA) efficiency.
Energy usage is now a major concern to operators, broadcasters and consumers, both from an operating cost and environmental impact standpoint.
Nujira’s technology can significantly improve PA efficiency, reducing radio network power consumption by up to 50%, and significantly improving handset battery life.

High accuracy tracking technology
Evolving standards - including WCDMA, WiMAX and OFDM demand linear PAs which are inherently inefficient with real-life, variable amplitude signals. Typical PA efficiency with conventional technology can be as low as 10-15%.
Nujira’s High Accuracy Tracking (HAT™) technology uses advanced envelope tracking (drain modulation) techniques to achieve PA efficiencies of 45% and more, even with high Crest Factor signals. Unlike other techniques proposed to improve PA efficiency, Nujira's technology is inherently broadband, modulation agnostic, multi-mode capable and is applicable to all PA device technologies.
