(Phys.org)—Whether cellular calls, texting, instant messaging, there's more to communications than content: every exchange leaves behind an electronic trace that can be measured and studied. Recently, researchers led by Prof. Wei-Xing Zhou at East China University of Science and Technology and by Prof. H. Eugene Stanley at University of Boston studied intercall durations of the 100,000 most active cell phone users of a Chinese mobile phone operator. They found that these durations form three clusters – robot-based callers, telecom fraud and telephone sales – that follow a power-law distribution, but also found that calling patterns of individual users formed a fourth cluster that followed a Weibull distribution. The researchers conclude that their findings may enable a more detailed analysis of the huge body of data contained in the logs of massive numbers of users. http://phys.org/news280477747.html Other Sciences Thu, 21 Feb 2013 09:00:02 EST news280477747 From banks to telecom providers, various industries are moving to pricing plans that offer a certain amount of "free" service. Bank customers are allowed a certain number of free ATM withdrawals each month, and cell phone users receive free minutes. These three-part plans—which also include a regular (usually monthly) access fee as well as a usage fee if the customer exceeds the free allotment—are replacing older two-part plans that charged an access fee and a usage price for every unit of consumption. http://phys.org/news279373119.html Other Sciences Wed, 06 Feb 2013 11:38:51 EST news279373119 Users of mobile devices are rejecting or uninstalling some apps because of concerns about how much personal and private information is collected, a US survey showed Wednesday. http://phys.org/news266059420.html Technology Wed, 05 Sep 2012 10:23:46 EST news266059420 (Phys.org)—Researchers have learned how to mass produce tiny mechanical devices that could help cell phone users avoid the nuisance of dropped calls and slow downloads. The devices are designed to ease congestion over the airwaves to improve the performance of cell phones and other portable devices. http://phys.org/news265566748.html Nanotechnology Thu, 30 Aug 2012 17:32:40 EST news265566748 Cellular networks leak the locations of cell phone users, allowing a third party to easily track the location of the cell phone user without the user's knowledge, according to new research by computer scientists in the University of Minnesota's College of Science and Engineering. http://phys.org/news248628878.html Technology Thu, 16 Feb 2012 15:35:14 EST news248628878 Though cellphones are usually considered devices that connect people, they may make users less socially minded, finds a recent study from the University of Maryland's Robert H.
