University of Waterloo computer science professor and Canada Research Chair Srinivasan Keshav recently told a US Senate committee that the actual cost to mobile phone carriers is not likely to exceed one-third of a cent. Yet, carriers charge up to 15 cents per text for pay-per-use customers—a 4,900 per cent markup. Last year, Canadians sent about 20.8 billion text messages. Keshav’s research in mobile systems helps Canadian consumers make more informed choices about their mobile products. He also co-invented “fair queuing”—a multitasking method used by computers and found in some version in every router worldwide. Keshav holds a Canada Research Chair in Tetherless Computing—the development of reliable, high-speed communication between portable smart devices and powerful computers.
