international solid-state circuits conference | 2011

Session 21 overview / wireless: Cellular

Myung-Woon Hwang; Taizo Yamawaki

Summary form only given. In most parts of the world the cellular mobile terminal market is starting to move from 2G and 3G to 4G systems in order to support higher date rates in the popular smart phones, netbooks and other mobile devices. These higher data rates are enabled by 3G standards such as WCDMA/HSPA and by 4G standards such as LTE. Another evolving direction is the removal of external components, aiming at lower-cost mobile devices and a higher integration level of functions, including a large number of bands and multistandard operation to guarantee global coverage.
