一个自制的小闹钟程序，程序可以配置，能够切换背景以及时间显示的外观，两者可以单独变换也可以一起变换。(A self-made small alarm clock program, the program can be configured, can switch the time display background and appearance, the two can be alone together can also transform transformation.)

The book focuses very much on impulse radio UWB techniques rather than multiband systems. The reasons for this are both practical and historical. The promise of UWB was low complexity, low power and low cost. Impulse radio, being a baseband technology, holds the most promise to achieve these three benefits.
