Millimeter Wave application<br />
Why do we need millimeter wave at now?<br />
Change of mobile communication<br />
Page-12<br />
analog sound -> convolution of control date -> digital sound -> digital data<br />
-> still picture -> movie.....<br />
Expansion of IP based network to achieve ubiquitous networking<br />
requires seamless connection between fixed network <strong>and</strong> mobile network<br />
[Problem]<br />
Short of communication b<strong>and</strong><br />
Advantages of millimeter wave<br />
[Countermeasures]<br />
Modulation method -> OFDM, MIMO....<br />
Higher frequency -> Millimeter wave....<br />
less interference <strong>with</strong> other systems / no other system in this b<strong>and</strong> / easy to<br />
control directivity / physical concealment due to propagation characteristic /<br />
absorbed in the air / hard to diffract / 7 GHz b<strong>and</strong>width available <strong>with</strong>out license …
