Yog li, qhov qis dua multicast tus nqi , qhov txuas ntxiv mus, lossis ntau qhov tseeb, qhov tsis muaj zog ntawm lub teeb liab wireless, raug tso cai txuas.

Kuj paub, NPHY tus nqi yog dab tsi?

NPHY rate : Teeb lub cev txheej ( NPHY ) tus nqi . Cov no tus nqi tsuas yog siv tau thaum 802.11n hom tau teeb tsa ua Tsis Siv Neeg. Tsis siv neeg 802.11n tiv thaiv: Yog tias koj xaiv qhov kev xaiv no, lub router yuav siv Kev Thov Xa / Ncua Xa (RTS / CTS) txhawm rau txhim kho kev ua tau zoo hauv 802.11 ib puag ncig sib xyaw.

Wireless multicast forwarding txhais li cas?

Wireless Multicast Forwarding (WMF) yog ib txoj hauv kev zoo rau pem hauv ntej tsheb khiav ntawm lub wireless network. Nws kov yeej cov teeb meem kis tau tus mob los ntawm kev xa tsheb mus rau cov tswv cuab ntawm lub hom phiaj multicast . WMF siv Internet Group Management Protocol (IGMP) kom taug qab cov neeg koom nrog pab pawg.
