Namuhla i-intanethi ayiyona nje injabulo, kodwa isidingo. Izikole ze-elekthronikhi ze-elekthronikhi, izingqungquthela ze-Skype, ukuthunyelwa kwe-imeyli - konke lokho kukhona empilweni yansuku zonke yomuntu othuthukile. Ngihlobo luni lomgwaqo okumelwe ngiwukhethele indlu yami? Uma umndeni wakho usebenzisa ngokugcwele amaphilisi namakhompyutha amaningi, kungcono ukuthenga umzila we-Wi-Fi wendlu. Ngakho, ulahla ikhebula elide futhi ungaxhuma amadivaysi amaningana kwinethiwekhi ngesikhathi esifanayo.
I-home home routers
Ngaphambi kokuba uqale ukhetha u-router udinga ukuqonda isimiso sokusebenza kwayo. Umsebenzi wedivayisi ungachazwa ngamagama amaningana: xhuma kwinethiwekhi yomhlinzeki okhethiwe futhi "udlulise" i-intanethi kuwo wonke amadivayisi axhunyiwe. Ngaphansi kwecala kukhona i-port eyodwa ye-WAN yekhebula lomhlinzeki namaphakheji amaningi we-LAN ukuze uxhumano oluxhunyiwe kwi-Intanethi. Ngakho-ke, amakhompyutha amadala namabhokisi asethempelini angasisekeli umsebenzi we-intanethi angasebenzisa ikhebula, futhi amaphilisi amaningi namanje ama-laptops azokwazi ukuthola i-intanethi "emoyeni."
Uma sicabangela ukuhamba ngezimpawu zobuchwepheshe bokudluliswa kwedatha, khona-ke kunamaqembu amabili: i-ADSL routers nama-router LTE. Uhlobo lokuqala lwe-routers lusebenza kusukela kumakhalekhukhwini. Isivinini sokwamukelwa kwedatha ngu-10 Mb / s, futhi ukudluliswa ngu-700 Kb / s. Ama-router e-LTE asebenza ngamanethiwekhi weselula (3G no-4G). Ukudluliswa kwesibalo kwedatha kwenzeka ngesignali yomsakazo. Kodwa-ke, lolu hlobo lokuxhumana lubiza kakhulu futhi luyashesha futhi lufanelekile kulabo abavame ukuhamba emgwaqweni.
Ukukhetha okuhle komgwaqo wendlu kuyisidlali se-ADSL.
Ungakhetha kanjani i-router yendlu?
Ukuze ungadideki ngesikhathi sokuthenga komgwaqo udinga ukwazi imingcele eyisisekelo yegajethi. Okokuqala, zithande izici zobuchwepheshe. Kuxhomeke kubo ukuthi ungakanani umthamo onamandla we-Wi-Fi wendlu oyithathayo. Amadokhumenti angatholakala kwiwebhusayithi yomkhiqizi noma imiyalelo eya ku-router. Izici ezilandelayo zibalulekile:
- Inani le-RAM (RAM) . Lokhu kuncike ngesivinini semilayezo, isikhathi sokuqala kabusha, ukulondolozwa kwemilayezo. Inkumbulo kufanele ibe okungenani engu-64 MB.
- Imvamisa yeprosesa (RAM) . Leli nani linquma inombolo yokusebenza ngeyunithi yesikhathi. Imvamisa efanelekayo ye-router i-500-800 MHz.
- Ukufakwa kwe-intanethi okungenantambo . Lesi sici sibalwa ngokuvumelana nezimo ezinhle: ukungabikho kwezingxenye, umsakazo osebenzayo noma i-TV. Khumbula ukuthi uma ucacisa indawo engamamitha ayi-100, khona-ke efulethini lomuzi cishe lizoba ngu-20 m.
- I-Antenna . Isivinini sokudluliswa kolwazi sincike kwinani lama-antenna. I-antenna eyodwa yenza umsebenzi wokudlulisa nokuthola idatha, futhi ama-antenna amabili asakaza umsebenzi wokudlulisela-wamukeleka ngendlela efanayo, ngakho-ke ijubane alinqunywanga. I-router ingaba nama-antenna angama-6.
- Ukusheshisa kwamachweba . Ukuhlola amameyili nokuvakashela amasayithi, ijubane lingama-100 mbps. Ukubuka ividiyo kudinga okungenani 150
mbit, futhi usebenze nabadlali be-intanethi nemidlalo ye-intanethi - 300 mbps.
Ngaphezu kwalokho, i-router yekhwalithi izoba nomlilo wokuzakhela, i-interface eyengeziwe ye-USB kanye nekhono lokubuyekeza (ukukhanyisa) idivaysi. Uma ufuna ukukhetha i-Wi-Fi router esheshayo yendlu enkulu, kungcono ukuthi ungalondolozi imali futhi uthenge i-router ngezici eziphezulu kakhulu zobuchwepheshe. Izohlinzeka nge-intanethi okusheshayo kuyo yonke ilungu lomndeni wakho futhi ngeke icasulwe "ukulenga" njalo nokusebenza kancane. I-router eshibhile ingabangela ukuxhumeka kokuxhumeka okuphakade, ukuvinjelwa ngesivinini (esikhundleni sama-30/30 Mbit / s amanani athole ama-16/4 Mbit / s), indawo encane yokufaka nokuvikeleka okuncane kusuka kumagciwane.
Ngaphezu kwalokho, ungaxhuma i- TV kumzila we-Wi-Fi.
