Smartphones could have better energy efficiency, Finnish researchers say
The researchers hope mobile phone users in the developing world will benefit most
Aalto University researchers claim they've quadrupled the energy efficiency of smartphones. This could improve mobile Internet access in developing countries.
A Finnish research team says it's slashed smart phone energy use by more than 70 percent - a finding that may help people in developing countries get better Internet access.
Smartphones - mobile phones that can run applications and use the Web easily - are on the rise worldwide. Recent industry analysis from Gartner shows that 115 million smartphones were sold worldwide in the third quarter of 2011 alone.
The key behind these new energy savings is a network proxy, which better organizes the flow of data between a mobile phone and the network, explained Jukka Manner, the lead scientist for the study at Aalto University, outside of Helsinki.
The team hopes to use a combination of new software on the phone and network proxy hardware to use the phone's cellular radio in a much more energy-efficient manner.
The team presented initial findings at the Africomm Conference in Tanzania last week. Manner told Deutsche Welle that the research has been peer-reviewed, and that in-depth findings would be published early next year.
Internet for developing countries
The researchers looked at use cases in Tanzania, Uganda and Kenya, hoping to develop solutions for times when access to electricity was difficult.
Aalto University researchers want to add another layer to existing mobile infrastructure"In Finland, it's annoying when you're to not be able to charge your phone. But in many places around the world, it's not just annoying, but impossible," Manner said.
Only about 11 percent of Africa's population has Internet access. Yet more than half of the people on the continent have mobile phones.
And according to the Finnish team's research, 90 percent Africans live in areas with mobile phone coverage.
Manner emphasized that though the team looked at cases in Africa, "the technology is not tied to any network or country," and can theoretically be implemented anywhere.
Proxy solution
A proxy is a device that gathers data requests from the phone, then sends them on to the network. Communication goes the other way as well, with the proxy receiving "answers" from the Internet to pass along to the mobile phone.
115 million smartphones were sold worldwide in the third quarter of 2011The we content proxy involves a "client application that talks to a dedicated server," Manner said, which organizes the flow of data.
Manner said the Web browser Opera works in a similar fashion.
The device can increase efficiency by, for example, sending bursts of data packets at one time rather than continuously. This results in more "sleep" time for the cell phone, saving battery use.
"It seems a fairly complex and sophisticated piece of technology they've developed," said Steve Furber, a professor at the School of Computer Science at the University of Manchester, in an interview with Deutsche Welle. Furber is also one of the designers behind the energy efficient ARM microprocessor, which is in use in many smartphones, including the iPhone.
Combined efficiency
The Aalto University researchers say they managed to cut power use from smart phones by up to 74 percent.
Although the proxy accounted for the bulk of saved energy, the researchers also utilized websites optimized for mobile phones, Web compression and better data caching to increase efficiency.
Manner noted that they didn't lower the data quality or use any sort of compression.
"We can probably go over 80 percent savings," Manner said.

TOKYO (Reuters) - Orix Corp , Japan's largest leasing company, and consumer credit firm Credit Saison are in merger talks, financial sources close to the matter said on Tuesday, seeking a deal to form a $106 billion finance group.
Orix has sounded out Mizuho Financial Group , Credit Saison's top shareholder, about selling its stake to allow the merger to happen, the sources told Reuters.

This expression derives from sound meaning "to measure the depth of water by lowering a line or lead." It was transferred to other kinds of inquiry in the late 1500s, but out was not added for several centuries.
