一直沒搞懂
1T1R = 1 transmitter, 1 receiver 是同一根天線同時收發嗎? 還是二根?
然而許多 mini pcie 卡 都有二個接頭算 2T2R 2 transmitter, 2 receivers 都接一黑一白應該是二根天線吧
又常標為 MAIN / AUX, 是一傳一收, 還是一個 wifi 一個 Bluetooth?

如果 1T1R 是一根天線 2T2R 是二根天線
為何 RTL8814AU (4T4R?) 模組 看起來像 六根或四根天線? 又說 3 spatial streams ?
中間二個黑色圓圈可能不是天線接頭? 4T4R 和 3 spatial streams 又有什麼關係?
