Tab 7.6. Kev sib piv ntawm IEEE 802.11 Cov Qauv
| IEEE Txuj | RF siv | Cov ntaub ntawv tus nqi (hauv Mbps) |
|---|---|---|
| 802.11 a | 5 GHz | 54 |
| 802.11 ib | 2.4GHz ceev | 11 |
| 802.11 g | 2.4gz ua | 54 |
| 802.11 | 2.4 / 5 GHz | 600 (theoretical) |
Kuj paub, tus qauv wireless twg tuaj yeem tshaj tawm cov ntaub ntawv ntawm tus nqi txog 54 Mbps siv zaus ntawm 5GHz?
Ntawm cov thev naus laus zis tau teev tseg, tsuas yog IEEE 802.11 n tus qauv wireless hais txog qhov xav tau. Cov 802.11 a Tus qauv wireless muaj qhov siab tshaj plaws ntawm 54 Mbps thiab siv 5 Ghz zaus ntau. Cov 802.11 g wireless tus qauv muaj qhov siab tshaj plaws ntawm 54 Mbps.
Ib tug kuj yuav nug, qhov twg cov ntaub ntawv kis tus nqi yog txhais los ntawm IEEE 802.11 b wireless standard? 802.11g thiab 802.11a ob qho tib si txhawb nqa cov ntaub ntawv kis ceev mus txog 54 Mbps. 802.11 ib txhawb nqa cov ntaub ntawv kis ceev mus txog 11 Mbps.
Raws li txoj cai, IEEE tus qauv twg tuaj yeem ua tiav qhov kev sib tw ntawm 54 Mbps?
Cov 802.11 tus qauv muab qhov siab tshaj plaws theoretical 11 Megabits ib ob (Mbps) cov ntaub ntawv tus nqi hauv 2.4 GHz Industrial, Scientific thiab Medical (ISM) band. Xyoo 2003, IEEE tau pom zoo rau 802.11 g tus qauv nrog qhov siab tshaj plaws theoretical cov ntaub ntawv tus nqi ntawm 54 megabits ib ob (Mbps) hauv 2.4 GHz ISM band.
Dab tsi yog qhov zaus thiab cov ntaub ntawv siab tshaj plaws rau 802.11 n?
Txawv Wi-Fi raws tu qauv thiab cov ntaub ntawv tus nqi
| raws tu qauv | Ntau zaus | Cov ntaub ntawv siab tshaj plaws (theoretical) |
|---|---|---|
| 802.11ac wb | 5 GHz yoj | 1.73gbps ua2 |
| 802.11ac wb | 5 GHz yoj | 866,7m wb2 |
| 8 02.11n | 2.4 lossis 5 GHz | 450 Mbps3 |
| 8 02,11g | 2.4 GHz ceev | 54mbps ua |
