VANU BOSE is the son of a fabled engineer, but he garnered no mercy when he presented his big idea at a technical conference in 1996. Mr. Bose’s graduate work at M.I.T. involved using software to handle the radio function in a cellular phone. He remembers that after he successfully demonstrated his technology, an audience member stood up and dismissed it with: “Congratulations! You’ve just invented the world’s most expensive cellphone.”
