In the future, mobile devices will have more and more access to all kinds of communications and multimedia services. They will have access not only to mobile-phone networks and the mobile Internet, but also to global-positioning systems, broadcasting services, WLAN (wireless-local-area-network) services, short-range connectivity, and many others. These future devices will also function in all kinds of situations - at home, in the office, during travel, and so on. ICs for these future mass-market wireless-communication consumer applications will be competitive only when they become small, energy efficient, and cost-effective.
