Bluetooth is changing small-area networking into a wireless and automatic connection with no need for user intervention and low need of transmission power. [br] Bluetooth networking transmits data via low-power radio waves between 2.402 GHz and 2.480 GHz.
选项
A、Y
B、N
C、NG
答案
A
解析
本题定位词是low-power radio waves,涉及蓝牙传输信息的频率,从而锁定Bluetooth Operation部分。该部分第一段提到:It communicates on a frequency of 2.45 gigahertz(actually between 2.402 GHz and 2.480 GHz,to be exact)。题干中表述的蓝牙使用频率与文章事实一致,故判断本题正确。
