I-eriyali efanelekileyo ye-wifi
La I-eriyali efanelekileyo yeWiFi Kwezi 5 zingentla yi-Melon N89A, enye yeemodeli ezilungileyo kakhulu ngokomgangatho wexabiso / enye yeendlela ezilula ukuyifaka, ilungele ukusetyenziswa kwangaphakathi / ngaphandle, nge-24dBi kunye ne-2000mW, kunye ne-chipset enamandla yeRalink. Le eriyali ayizukunceda kuphela ukuba ubambe imiqondiso ye-WiFi ekude okanye ebuthathaka ongakwaziyo ukuyibamba kunye neadaptha yakho yenethiwekhi, kodwa kuluncedo ukufota umqondiso kwiinkampu, kwiindawo ezisemaphandleni, kunye nokwenza uphicotho lweWiFi.
I-eriyali yeWiFi yePC: zisebenza njani?
Omnye I-antenna yokukhulisa i-WiFi sisixhobo esikwaziyo ukwandisa amandla okubamba eeadaptha zomdibaniso ezihlanganisiweyo ezibandakanya izixhobo ezininzi ezinjengeeselfowuni, iipilisi, iiTV ezikrelekrele, iikhompyuter, njl.
Olu hlobo lwee-eriyali ze-WiFi zePC zingakunceda sombulula iingxaki ezininzi ukubanjwa komqondiso, nokuba kusekhaya, emsebenzini, enkampini, okanye nakweyiphi na indawo kawonke-wonke. Xa uhlupheka kunxibelelwano lwe-WiFi olubuthathaka ungayiphelisa ingxaki ngolunye lwee-eriyali ekungekho mqondiso ukude kakhulu ukuba ungayibamba (ngaphakathi kokunokwenzeka, kunjalo).
Ngokusisiseko kunjalo umda enokuqhagamshelwa ngezibuko le-USB kwiPC yakho kwaye ubambe zonke iinethiwekhi ze-WiFi kuluhlu lwayo, ezinokuthi ngamanye amaxesha zibe ngamakhulu eemitha kunye neekhilomitha.
Oko kukuthi, kuyasebenza njengempinda kodwa kungenjalo, into eyenzayo yile fumana umqondiso okubonayo kwaye ukwandise ukuze iqela lakho lizuze kulo ngokungathi likufutshane.
Yintoni i-eriyali ye-WiFi yangaphandle?
Uluhlu lwee-eriyali ze-USB ezide zinokuba nazo izinto ezahlukeneyo. Ukongeza kukuvumela ukuba ubambe umqondiso weWiFi okude okanye obuthathaka ngendlela engcono, ikwanazo nezinye iinkqubo ezinomdla kakhulu.
Ezinye ze ezona zicelo zibalaseleyo Zizo:
- Qhagamshela kwi kude okanye ubuthathaka uphawu lwe-WiFi ongenakukwazi ukufikelela kuzo ngeadaptha zenethiwekhi eziqhelekileyo. Ukugqunywa kwenethiwekhi ye-WiFi kunokufikelela kwiimitha ezimbalwa, kodwa ukuba ngasizathu sithile ukude kakhulu, olu hlobo lwee-eriyali luya kuba yile nto uyifunayo.
- Qhagamshela Iimpawu zasimahla zeWiFi zikawonke-wonke ezingenamandla ngokwaneleyo okuthatha apho ukhoyo.
- Ukuthatha imiqondiso kwizithuthi ezinjengeelori, kwiikharavani / kwizindlu zeemoto, kwi sihlala, Njl
- Uvavanyo usulelo yi-WiFi phakathi kwamanqaku amabini.
- Qaphela uphicotho lwezokhuseleko uthungelwano lwe-WiFi, oko kukuthi, ukufaka umqondiso wenethiwekhi ekufuphi ukujonga ukhuseleko lwayo usebenzisa izixhobo zokukhangela inethiwekhi. Ezi ntlobo zezixhobo zinokufumaneka kunikezelo lwe-GNU / Linux ezinje ngeWifiSlax, iKali Linux, njl. Kwaye kunjalo, banokusetyenziswa okuphindwe kabini, kuba zikwasetyenziswa ngabanye ukuqhekeza iinethiwekhi kwaye banxibelelane nabo ngaphandle kokuhlawula ...
Ukuqwalaselwa ekukhetheni i-eriyali
Zininzi Ukuqwalaselwa ekufuneka kuthathelwe ingqalelo xa kuziwa ekukhetheni imodeli elungileyo xa kuziwa kwi-antenna ze-WiFi ze-USB. Ukwenza ukhetho lwakho ngokuchanekileyo, ndingacebisa ukuba ufunde la macandelo alandelayo ...
Ngaphandle ngaphakathi
Eyokuqala yile Yazi injongo ye-WiFi. Ayifani ukuba ufuna i-eriyali oyisebenzisa ekhaya, okanye eofisini, kunokuba ufuna i-eriyali ukuyifaka ngaphandle. Ii-eriyali ezininzi zikulungele ukusetyenziswa ngaphakathi nangaphandle, kwaye yangaphandle inokusetyenziselwa ngaphakathi ngaphandle kwengxaki, kodwa hayi ngenye indlela, kuba ayikhuselwanga kwimozulu ethile engathandekiyo.
Idilesi
Nje ukuba wazi uhlobo lwe-eriyali I-WiFi ofuna oku kulandelayo kukumisela ukuba iza kubekwa phi okanye ukuba i-eriyali iya kwalathiswa njani. Oku kuya kuxhomekeka kwinjongo kunye nobungakanani bezithintelo onokuzifumana kwindawo yakho.
Kwelinye icala unezo uhlobo olungasasebenziyo. Kule meko, ukuphakama kwesiginali esifakwe kwicala elinye kuya kuphuculwa. Oko kukuthi, xa usazi kakuhle apho uvela khona umqondiso wesiginali ye-WiFi kwaye ungakhomba ngokufanelekileyo kuloo ndlela uyibambe.
Kwelinye icala unezo ezinokusebenza kumacala amaninzi, njenge-bidirectional okanye I-eriyali ye-WiFi omnidirectional. Kule meko, isiginali iya kufakwa kwiradiyo ebanzi kakhulu, kwaye zilunge ngakumbi xa ungafuni ukufaka isiginali ethile, kodwa zonke iirediyo kwindawo leyo.
Kukho ezinye iintlobo yee-eriyali, nangona zincinci rhoqo, ezinje ngento ebizwa ngokuba yiYagi, umva, umzekeliso, njl.
Indlela yeSitishi / Imo yeAP
Iimodeli ezininzi ze-eriyali ye-USB ye-WiFi isebenza kuphela imo yesikhululoOko kukuthi, banakho ukubamba umqondiso okude ukuze bakwazi ukuwandisa kwaye bawenze ngokwaneleyo ukuba banokunxibelelana nomnatha lowo.
Ezinye zinokusebenza kwimowudi eyongezelelweyo, eyi Imowudi ye-AP (Indawo yokufikelela). Esi sisibonelelo esihle, kuba asizukukwazi ukwenza kuphela okwenziwe kwimowudi yesikhululo, kodwa inokusebenza njengendawo yokufikelela ngokusasaza i-WiFi kwezinye izixhobo kwindawo yakho.
Oko kukuthi, ii-eriyali ezisebenza kwimowudi yesitishi kunye nemowudi ye-AP inokubamba zombini imiqondiso ekude ukubonelela ukufikelela kwi-PC abanxibelelana ngayo nge-USB kunye nokusebenza njenge "WiFi router" ukudibanisa ezinye izixhobo ezinje ngeefowuni eziphathwayo, iipilisi, oomabonakude, njl. Konke ngaphandle kwesidingo sokunxibelelana nentambo ... Ngamanye amagama, ukuba into oyifunayo ikwayi- I-eriyali yeWiFi yeselfowuni, ezi zinokukhetha.
Ukuzuza / umgama
Uluhlu lwee-eriyali ze-USB zexesha elide zineeyunithi ezithi Chonga amandla noluhlu yee-eriyali. Banokuvela kwi-eriyali efikelela kwiimitha ezimbalwa, ukuya kwi-antenna ye-5Km ye-WiFi kwaye nangaphezulu kwezinye iimeko.
Ukuphakama kwamandla, ubukhulu becala. Ngenxa yoko kuya kufuneka ujonge kwezi yunithi zilandelayo:
- dBmIsishunqulelo seyunithi ye-decibel-milliwatt, oko kukuthi, iyunithi yamandla achazwe kwi-dB xa kuthelekiswa ne-mW enye. Isetyenziswa ngokubanzi kunomathotholo, kwimicrowave kunye nakwiinethiwekhi zefayibha kwaye ichonga amandla okuphuma ngokupheleleyo, yinto enomdla kuyo ukuba uza kuyisebenzisa njenge-AP.
- dBi: Iyunithi elilinganiswe nge-dB ukubonisa amandla e-eriyali ngokuthelekiswa ne-eriyoli ye-isotropic, oko kukuthi, eyahlula amandla kuwo onke amacala. Ezinkulu kwezi yunithi, kokukhona uya kufumana uluhlu / uvakalelo. Umzekelo, ukukunika umbono:
- 0dB=200m
- 4dB=440m
- 7dB=620m
- 10dB=1.2km
- 16dB=5km
- 20dB=12.5km
- 24dB=31km
Njengoko ubona, azizizo iiyunithi zomgca, kodwa ziyaxhuma ...
Ukungenelela
Kananjalo akufuneki ulibale olunye uqwalaselo xa ukhetha, kwaye lelo lixabiso lokuphazamiseka okanye imiqobo onokuyifumana. Ngokuqinisekileyo sele uyazi loo miqondiso yokuhamba rhoqo 2.4Ghz Azikhawulezi kangako, kodwa ekubuyiseleni zibonelela ngokugubungela ngakumbi kwaye zidlula ngcono imiqobo abanokuhlangabezana nayo (iingcango, iindonga, imizimba yamanzi, ii-microwave kunye nokunye ukuphazamiseka kombane, njlnjl.).
Kunoko, 5Ghz inikezela ngesantya esiphezulu kakhulu, kodwa ayinakugqobhoza kwaye iya kuba sesichengeni ukuba kukho imiqobo ethile phakathi.
Ukuhambelana
Okokugqibela, olu hlobo lwee-eriyali ze-WiFi ze-USB zihlala zinefayile ye- ukuhambelana okuhle ye-Microsoft Windows, nangona zinokusebenza kwi-macOS, i-GNU / Linux kunye nezinye iinkqubo zokusebenza nokuba ayichazwanga, kuba kuhlala kukho abaqhubi abakwizinto eziqhelekileyo kwezinye ii-SSOO. Kwakhona i-USB lizibuko eliqhelekileyo, ke ngekhe ube nengxaki kolu nxibelelwano.
Ezinye ii-eriyali zeWiFi zihlala zinxibelelana nazo amanye amazibuko, ezinje nge-RJ-45 ukudibanisa ngokuthe ngqo kwi-router (umzekelo, njengee-eriyali ze-parabolic ukulungiselela isathelayithi, okanye i-WiMAX), njl.
Kuya kufuneka unike ingqalelo nokuba bayayixhasa na enye okanye enye rhoqo, nangona uninzi lukhona I-Dual band (2.4 / 5Ghz), ke ngekhe ube nengxaki enkulu. Kodwa khumbula ukuba izixhobo ezininzi ezingekhoyo ngoku azixhasi i-5 kwaye ziyahambelana kuphela ne-2.4.
Okufanayo kuya Imigangatho ye-WiFi engama-802.11, qinisekisa ukuba ziyahambelana nezixhobo zakho. Ubuncinci bayayamkela i-802.11 a / b / g / n / ac.
