LOS: WirelessMAN- SC 10-66HZ
NLOS: WirelessMAN- OFDM 2-11HZ
問題：
為什麼高頻的適用在LOS 是因為波長的問題 造成他不容易反射嗎???
那利用高頻或是低頻有什麼優缺點??(成本？ modulation 難？)

: 我們都知道 LOS 是 line of sight
: NLOS = No Line of sight<---這兩個定義我知道
: 我想要問的是頻率的問題 在ＰＨＹ layer
: WiMAX Variants 有五種版本 就LOS 和NLOS(或是以頻率來區分)
: LOS: WirelessMAN- SC 10-66HZ
在這頻率~基本上可以使用的頻寬會相對增加
用SC的方式即可達到high data rate
但是頻率高path loss會很嚴重,所以不會傳太遠(有限能量下)
有效傳輸距離大約只有幾公尺以內,對於frequency reuse可以做到很好
: NLOS: WirelessMAN- OFDM 2-11HZ
OFDM基本上對frequency selective fading channel能有有效的處理方式
2.5GHz將會為下一階段釋放出來的頻段,考量為頻率高cell的path loss嚴重
: 問題：
: 為什麼高頻的適用在LOS 是因為波長的問題 造成他不容易反射嗎???
波長短確實穿透效果好,但是loss嚴重
: 那利用高頻或是低頻有什麼優缺點??(成本？ modulation 難？)
60GHz的電路不管在調變,mixer,等等..都會是問題~
也會造就許多碩博士
