Helping radio networks ‘go green’ — and reducing network OPEX
Modern radio and broadcast technologies such as WCDMA, WiMAX and DVB provide consumers with high bandwidth mobile connectivity ‘on the move’, but at a cost - high network power consumption due to the poor efficiency of the RF power amplifiers (PAs), which often account for over half the power consumption and heat dissipation of a 3G base station.
High power consumption translates directly to high operator OPEX and a significant environmental impact, both of which are now increasingly unacceptable.
Nujira’s technology can make a significant contribution to improving PA efficiency, improving this from the 15% of ‘traditional’ PAs to 45% and more - resulting in a dramatic reduction in network power consumption.
How Nujira can help…Network Operators
Radio networks normally account for around 80% of the total electricity used by an operator, and so the power consumption of each cell or transmitter site is a critical factor in helping operators meet their critical OPEX and environmental impact targets.
Nujira’s technology has the capability to potentially reduce network energy consumption by 50%, increasing network profitability and helping operators’ ‘green’ credentials.
Additional benefits arising from the use of the HAT™ technology include lower maintenance costs and greater reliability through reduced heat dissipation, and lower site installation and CAPEX costs as a result of the reduction in equipment size and footprint, and battery backup, which Nujira’s technology allows.
How Nujira can help…Equipment Vendors
Nujira’s technology allows the design of smaller and cheaper base stations and transmitters that better match the increasingly-challenging requirements of operators and broadcasters. By adopting Nujira’s technology, equipment vendors can maintain competitiveness in an increasingly difficult marketplace.
In addition, the inherently broadband nature of Nujira’s technology (in contrast to other efficiency-enhancing techniques) allows the design of broadband PAs that can be deployed in a flexible manner to support different frequency allocations worldwide, reducing inventory requirements.
How Nujira can help…Silicon Vendors
By working with Nujira and designing RF devices optimised for use with HAT™ technology, silicon vendors can offer PA designers a better choice for tomorrow’s ultra-high efficiency PAs.
