Uluhlu lwenethiwekhi yekhompyutheni ye-WiFi luxhomekeke ngokukodwa kwinani kunye nohlobo lokungena kwezixhobo ezingenazintambo (kubandakanywa ii-routers ezingenazintambo) ezisetyenziselwa ukwakha.
Umnatha womncedi womhlaba onomzila omnye ongenazintambo unokugubungela indawo yokuhlala yentsapho kodwa kaninzi ayininzi. Iintanethi zoshishino kunye neendawo zokufikelela kwiingongoma ziyakhusela izakhiwo ezinkulu zeofisi. Kwaye kwakhiwe ii-hotspots ezingenazintambo ezineekhilomitha ezili-square (iikhilomitha ezili-km) kwezinye iidolophu. Iindleko zokwakha nokugcina ezi nqanki zanda kakhulu njengoko ukhula luya kwanda, kunjalo.
Uluhlu lwesigxina se-WiFi lwalowo naluphi na uluhlu lokufikelela luye lwahluka kakhulu kwicebo ukuya kumadivayisi. Izinto ezibonisa ukuba uluhlu lokufikelela kwindawo enye zibandakanya:
- i- 802.11 protocol isebenza
- amandla okuthumela umbane
- uhlobo lokukhutshwa ngokomzimba kunye / okanye ukuphazamiseka kwomsakazo kwindawo ejikelezile
Umgaqo oqhelekileyo wezithupha kwi-intanethi yekhaya uthi ii-routers ze-WiFi zisebenza kwi-2.4 GHz band bandifinyelela kwii-150 m (46 m) ngaphakathi nangamamitha angama-92 ngaphandle. Ama-router angama-802.11a asebekhulile aqhutywa kwiinqwelo ze-5 ze-GHz zafikelela malunga neyesithathu kule migama. Iindlela ezintsha zokuhamba ezingama-802.11n kunye ne-802.11ac ezisebenza kwii- 2.4 GHz kunye ne-5 GHz zamaqela ziyahluka ngokufanayo.
Ukuphazamiseka komzimba kumakhaya afana nezindonga zezitena kunye nezakhelo zetsimbi okanye ukunciphisa intlobo yeenethiwekhi ze-WiFi ngama-25% okanye ngaphezulu. Ngenxa yemithetho ye-physics, u-5 GHz uxhumano lwe-WiFi luyakwazi ukuphazamiseka ngaphezu kwe-2.4 GHz.
Ukuphazamiseka kwempawu zomsakazo kwiivenki ze-microwave kunye nezinye izixhobo nazo zichaphazela kakubi uhla lwee-WiFi. Ngenxa yokuba ii-radios ezingama-2.4 zeGHz zisetyenziselwa kwizixhobo zobuchwephesha, ezo protocol ze-WiFi ziyakwazi ukuphazamiseka kwizakhiwo zokuhlala.
Ekugqibeleni, umgama apho umntu angakwazi ukudibanisa kwindawo yokufikelela kuyohluka ngokuxhomekeka kwi-oriented antenna. Abasebenzisi be-Smartphone, ngokukodwa, banokubona amandla abo okuxhunywa okanye banciphise ngokucwangcisa idivaysi kwii-angles ezahlukeneyo. Ukongezelela, amanye amanqaku okufikelela asebenzisa i- antennas ezikhokelayo ezenza ukuba zifikelele kwiindawo apho i-antenna ibonisa kodwa kufinyelele emfutshane kwezinye iindawo.
Kukho iintlobo zee routers ezikhoyo kwimarike. Ngezantsi zikhethi zam ezinye zabathengisi abahamba phambili, kwaye zonke zingathengwa kwi-Amazon.com:
802.11ac Routers
I-TP-LINK Archer C7 AC1750 iDual Band Wireless AC Gigabit Router ibandakanya i-450Mbps kwi-2.4GHz kunye ne-1300Mbps kwi-5GHz. Inomsebenzi wokunxibelelana kweenethwekhi zokungcebeleka xa ufuna ukwabelana ngekhaya lakho, kwaye uza nomncedisi wokuseta lula ngokuncediswa kweelwimi ezininzi ukwenzela inkqubo yokufaka elula.
Iinqununu ezingama-802.11ac ezingenazintambo
802.11n Routers
I-Netgear WNR2500-100NAS IEEE 802.11n 450 Mbps I-Wireless Router iya kwenza ukukhuphela iifilimu, iingoma, ukudlala imidlalo kunye nokusabalalisa ngokukhawuleza. Amandla akhuthaza ama-antenna aqinisekise ukuba unxibelelwano olunamandla kunye nobubanzi obubanzi.
802.11g Routers
I-Linksys WRT54GL i-Wi-Fi engenazintambo ze-Broadband Router ineenkalo ezine ze-ethernet ezikhawulezayo kunye ne-WPA2 encryption ikuvumela ukuba ungene kwi-Intanethi ngokukhuselekileyo.
