Introduction to Power Management in Portable Personal Devices
LTE ’ s computational requirement is approximately 3,000 times that of basic 3G service.
The peak transmit po
wer requirement is twice that of basic 3G. Additionally, two more
radio frequency (RF) bands need to be supported. At the same time, we must fi nd
implementation techniques that enable LTE-based phones at roughly the same size, price,
and power consumption of today ’ s 3G phones. Using traditional approaches will not
satisfy these requirements.
Fourth generation (4G) cellular handsets will support TV in real time as well as video
downloads at broadband ...
