有沒有人了解什麼是minimum coupling loss? 我在網路上找半天越看越迷糊 我遇到的情況大概是這樣 Assume Pathloss' = P(d,theta) 由距離和antenna pattern計算出的loss and then Pathloss = max ( Pathloss' , minimum coupling loss) 名符其實的 "minimum loss" 參考值是70dB 但我不了解為什麼會有這樣一個minimum loss 而且又要取成minimum "coupling" loss --- 而跟我在網路上找到的minimum coupling loss method 或是這段定義 MCL is defined as the minimum possible propagation loss between stations of non-coordinated operators MCL is defined as the pathloss between a receiving station (the so-called victim) and its nearest interferer belonging to another operator in an adjacent frequency band 都有點牛頭不對馬嘴,感覺好像是不一樣的東西@@ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.96.158.68

顧名思義不是經由直接接觸而傳遞的訊號

,由空氣偶合至少損耗70dB不論距離
