Sucessful conclusion of C2POWER
Following the final review at the University of Surrey, Guildford, C2POWER has reached a sucessful conclusion.
With EUR 3.45 million in EU funding, C2POWER – whose partners included academia, private research bodies and telecoms operators – focused its efforts on two complementary and disruptive technologies for improving the energy efficiency of handsets:
- cooperative technologies - which allow nearby devices to work together in unison to find the most efficient way to access the web, and
- built-in cognitive technologies that allow future terminals to become context-aware and smart.
These two technology agnostic approaches exploited in tandem have been demonstrated to show energy saving as much as 50%.
However, beyond this energy saving marker, the project has impacted industry and the research community at large with innovations that include:
• Energy efficient connectivity and extended coverage through cooperation with neighboring handset devices.
• Energy efficient roaming for commercial mobile networks, that includes seamless handovers towards indoor femto-cells.
• Energy efficient node and network scanning protocols, which in the past have been notorious for consuming huge chunks of battery power: they were always “on”.
• New product line of handset devices for public safety agencies. C2POWER developed an energy efficient RF platform that accommodates multiple standards on the same chip including LTE. This will allow first responders to go beyond the conventional TETRA/TETRAPOL networks and migrate towards commercial LTE networks to make that critical call.
• New business models based on incentives for cooperation

C2POWER main objective is to research, develop and demonstrate energy saving technologies for multi-standard wireless mobile devices, exploiting the combination of cognitive radio and cooperative strategies while still enabling the required performance in terms of data rate and QoS to support active applications.
The promise of a truly mobile experience is to have the freedom to roam around anywhere and not be bound to a single location. However, the energy required to keep mobile devices connected to the network over extended periods of time quickly dissipates. In fact, the operational time, has been identified as the number one criteria by the majority of the consumers purchasing a mobile device. Moreover, concern about exhausting battery lifetime is also one of the main reasons why users do not opt to use advanced multimedia services on their mobiles more frequently.
To avoid the foreseen 4G “energy trap” C2POWER project will investigate, develop and demonstrate how cognition and cooperative strategies can be extended to decrease the overall energy consumption of mobile devices while still enabling the required performance in terms of QoS.
In particular, C2POWER will investigate two complementary techniques to increase power efficiency at the wireless interface of handsets:
- Cooperative power saving strategies between neighbouring nodes using low power short range communications
- Cognitive handover mechanisms to select the Radio Access Technology which has the lowest energy demand in heterogeneous environments
