| Coordinator | Huawei Technologies Sweden AB |

| Project duration | October 2011 - June 2014 |
| Status | Completed |
Purpose and goal
The goal of Green-T is to develop and evaluate solutions for energy efficient mobile terminals, for example smartphones. Mobile terminals have evolved with new functions and usage areas, but unfortunately the battery capacity has not developed at the same pace. The project has developed solutions to communicate in energy efficient ways by effective use of the functionality of modern terminals, for example computational power, memory, positioning and multiple radio interfaces.
Results and expected effects
Huawei has developed and evaluated solutions in two technical areas. The first one is efficient usage of multiple radio interfaces, where we have found that Wi-Fi has good potential for energy efficient communication. Therefore, we have developed a solution for energy efficient mobility in 802.11. The second area is cooperation between terminals for energy efficient communication, where the most promising solution we developed uses separate path selection for uplink and downlink.
Approach and implementation
The project has been carried out in cooperation with partners within the Green-T Celtic consortium, which led to some challenges when partners left the project due to lack of funding in some countries. The subproject of Huawei has progressed well, and the studies have mainly been performed by means of simulations. The cost of the project has been kept below the budget since parts of the studies have been performed by young researchers under supervision of senior researchers.
