2,4 GHz võrk kuupitsa




Mis tüüpi WLAN võrguga on arvuti ühendatud? infrastructure


Milline on lubatud laadimiskiirus üles ja alla? 54 MBit/s


5 GHz võrk anjakatja











Mis tüüpi WLAN võrguga on arvuti ühendatud? infrastructure

Milline on lubatud laadimiskiirus üles ja alla? 867 MBit/s





Programmi inSSIDer 3 ekraanipilt



2,4 GHz võrk kuupitsa









5 GHz võrk anjakatja















Küsimused:




Kui suur sagedusriba on kasutuses Teie seadistatud WLAN võrkudele 2,4 GHz ja 5 GHz sagedusalal? 

2.4 GHz võrk: 30 MHz, 5 GHz: 84 MHz


Kui suurt andmeedastuskiirust teoreetiliselt on võimalik kasutada Teie WLAN võrkudes? 

2.4 GHz võrk: 54 Mbps

5GHz võrk: 450 Mbps


Selgitada inSSIDer'i tabelis näidatavate MAC aadresside tähendust. See võimaldab leida kohtvõrgus sihtkohaks oleva võrguseadme


Millised raadiokanalid on kasutuses ja kus on veel vaba ruumi uute võrkude jaoks?

                                      2,4 GHz võrk kuupitsa                        5 GHz võrk anjakatja         

Kasutuses:                        6                                                        112,116

Vaba:                      1 kuni 5, 7 kuni 13                      100 kuni 108, 120 kuni 140











4. WLAN võrgu kiiruste uurimine






























802.11g (2,4 GHz) võrk:

SSID: kuupitsa, kanal: 6




Hinnang TCP katsetulemustele:Teoreetilisest kiirusest on 3 korda madalam. Halb.






Hinnang UDP katsetulemustele:On ka teoreetilisest kiirusest 3 korda madalam. Halb!

[mW]  : N = 10 astmes (-97 / 10) = 10 astmes -9,7 mW

[kordades] : S/N = 10^(-4,5) / 10^(-9,7) = 158489

[Mb/s]: R = 1 Mb / s
[MHz] : W = R / log2(1 + S/N) = 1 / log2(158489) = 0,009 MHz

















Kokkuvõte ja järeldused

Sain uurida kuidas wi-fi võrk levib ja töötab, kanalite ja sageduste jaotumist ning wi-fi signaali kuju.
