The world’s congested mobile airwaves are being divided in a lopsided manner, with 1 percent of consumers generating half of all traffic. The top 10 percent of users, meanwhile, are consuming 90 percent of wireless bandwidth. Arieso, a company in Newbury, England, that advises mobile operators in Europe, the United States and Africa, documented the statistical gap when it tracked 1.1 million customers of a European mobile operator during a 24-hour period in November. The gap between extreme users and the rest of the population is widening, according to Arieso. In 2009, the top 3 percent of heavy users generated 40 percent of network traffic. Now, Arieso said, these users pump out 70 percent of the traffic.
