Cov khoom lag luam tseem ceeb ntawm ntau lub khoos phis tawj hauv tsev yog lub router wireless. Cov routers no txhawb nqa txhua lub computer hauv tsev teeb tsa nrog wireless network adapters (saib hauv qab). Lawv kuj muaj lub network hloov pauv kom tso cai rau qee lub khoos phis tawj txuas nrog Ethernet cables.
Wireless routers tso cai rau cable modem thiab DSL internet sib txuas. Tsis tas li ntawd, ntau yam khoom siv wireless router muaj xws li cov firewall built-in uas tiv thaiv lub tsev network los ntawm intruders.
Ib qho duab saum toj no yog Linksys WRT54G. Qhov no yog cov khoom siv wireless router nrov raws li 802.11g Wi-Fi network tus qauv. Wireless routers yog lub thawv me me zoo li cov khoom siv feem ntau tsawg dua 12 ntiv tes (0.3 m) ntev, nrog LED teeb nyob rau pem hauv ntej thiab nrog cov chaw sib txuas ntawm ob sab lossis nraub qaum. Qee lub wireless routers zoo li WRT54G muaj cov kav hlau txais xov sab nraud uas protrude los ntawm sab saum toj ntawm lub cuab yeej; Lwm tus muaj cov kav hlau txais xov built-in.
Wireless router cov khoom sib txawv hauv cov txheej txheem network uas lawv txhawb nqa (802.11g, 802.11a, 802.11b lossis kev sib txuas), ntawm cov xov tooj ntawm cov khoom siv sib txuas uas lawv txhawb nqa, hauv kev xaiv kev nyab xeeb lawv txhawb, thiab ntau lwm yam txoj kev me me. Feem ntau, tsuas yog ib lub wireless router yuav tsum tau txuas rau tag nrho tsev neeg.
Wireless Access Points

Ib qho chaw nkag wireless (qee zaus hu ua "AP" lossis "WAP") ua haujlwm koom lossis "choj" cov neeg siv wireless mus rau ib lub xov tooj Ethernet. Cov ntsiab lus nkag mus rau hauv nruab nrab txhua tus neeg siv WiFi ntawm lub network hauv zos hauv qhov hu ua "infrastructure" hom. Ib qho chaw nkag, tig, tuaj yeem txuas mus rau lwm qhov chaw nkag, lossis mus rau lub router txuas nrog Ethernet.
Wireless nkag mus rau cov ntsiab lus feem ntau yog siv hauv cov tsev ua haujlwm loj los tsim ib lub wireless hauv zos network (WLAN) uas nthuav dav thaj chaw loj. Txhua qhov chaw nkag tau feem ntau txhawb nqa txog 255 tus neeg siv computer. Los ntawm kev sib txuas cov ntsiab lus nkag mus rau ib leeg, cov tes hauj lwm hauv zos muaj ntau txhiab cov ntsiab lus nkag tuaj yeem tsim tau. Cov neeg siv khoos phis tawj tuaj yeem txav los yog taug kev ntawm txhua qhov nkag mus tau raws li xav tau.
Hauv kev sib tham hauv tsev, cov ntsiab lus nkag wireless tuaj yeem siv los txuas ntxiv lub network hauv tsev uas twb muaj lawm raws li lub router wired broadband. Qhov chaw nkag tau txuas mus rau broadband router, tso cai rau cov neeg siv wireless tuaj yeem koom nrog hauv tsev network yam tsis tas yuav rov xa lossis rov teeb tsa Ethernet kev sib txuas.
Raws li tau piav qhia los ntawm Linksys WAP54G qhia saum toj no, cov ntsiab lus nkag wireless tshwm sim lub cev zoo ib yam li wireless routers. Wireless routers yeej muaj qhov chaw nkag wireless ua ib feem ntawm lawv pob tag nrho. Zoo li wireless routers, cov ntsiab lus nkag tau muaj nrog kev txhawb nqa rau 802.11a, 802.11b, 802.11g lossis kev sib txuas.
Wireless Network Adapters

A wireless network adapter tso cai rau lub khoos phis tawj los koom nrog LAN wireless. Wireless network adapters muaj ib tug built-in xov tooj cua transmitter thiab receiver. Txhua lub adapter txhawb nqa ib lossis ntau dua ntawm 802.11a, 802.11b, lossis 802.11g Wi-Fi qauv.
Wireless network adapters kuj muaj nyob rau hauv ntau yam sib txawv. Traditional PCI wireless adapters yog ntxiv-hauv daim npav tsim los rau kev teeb tsa hauv lub khoos phis tawj desktop uas muaj lub npav PCI. USB wireless adapters txuas mus rau sab nraud USB chaw nres nkoj ntawm lub computer. Thaum kawg, thiaj li hu ua PC Card lossis PCMCIA wireless adapters ntxig rau hauv qhov qhib nqaim ntawm lub khoos phis tawj phau ntawv.
Ib qho piv txwv ntawm PC Card wireless adapter, Linksys WPC54G tau qhia saum toj no. Txhua hom wireless network adapter yog me me, feem ntau tsawg dua 6 ntiv tes (0.15 m) ntev. Txhua qhov muab sib npaug wireless muaj peev xwm raws li tus qauv Wi-Fi nws txhawb.
Feem ntau cov khoos phis tawj phau ntawv tam sim no tau tsim nrog kev sib txuas hauv wireless. Cov chips me me hauv lub computer muab cov haujlwm sib npaug ntawm lub network adapter. Cov khoos phis tawj no pom tseeb tsis tas yuav tsum muaj kev sib cais ntawm kev sib cais wireless network adapter.
Wireless Print Servers

Ib lub tshuab luam ntawv wireless tso cai rau ib lossis ob lub tshuab luam ntawv kom yooj yim sib koom thoob plaws Wi-nkaus network. Ntxiv wireless print servers rau lub network:
- Tso cai rau cov tshuab luam ntawv kom yooj yim nyob txhua qhov chaw hauv lub network wireless, tsis khi rau qhov chaw ntawm cov khoos phis tawj.
- Tsis xav kom lub computer ib txwm qhib kom luam tawm.
- Tsis xav kom lub computer tswj txhua txoj haujlwm luam tawm, uas tuaj yeem ua rau nws qhov kev ua tau zoo.
- Tso cai rau cov thawj coj hloov lub npe computer thiab lwm qhov chaw yam tsis tas yuav rov teeb tsa lub network luam ntawv teeb tsa.
A wireless print server yuav tsum txuas nrog cov tshuab luam ntawv los ntawm lub network cable, feem ntau USB 1.1 lossis USB 2.0. Lub tshuab luam ntawv nws tus kheej tuaj yeem txuas rau lub router wireless hla Wi-nkaus, lossis nws tuaj yeem koom nrog siv Ethernet cable.
Ntau cov khoom lag luam luam tawm suav nrog kev teeb tsa software ntawm CD-ROM uas yuav tsum tau muab tso rau hauv ib lub computer kom ua tiav qhov kev teeb tsa thawj zaug ntawm lub cuab yeej. Raws li nrog lub network adapters, wireless print servers yuav tsum tau teeb tsa nrog lub npe network tseeb (SSID) thiab encryption nqis. Tsis tas li ntawd, lub wireless print server xav kom cov neeg siv software raug ntsia rau hauv txhua lub computer xav tau siv lub tshuab luam ntawv.
Print servers yog cov khoom siv compact heev uas suav nrog lub kav hlau txais xov wireless thiab LED teeb los qhia txog xwm txheej. Lub Linksys WPS54G 802.11g USB wireless print server tau qhia ua ib qho piv txwv.
Wireless Game Adapters
