Yikuphi router kuhle kakhulu ukuba uwuthenge? Yikuphi-WiFi router kuhle kakhulu ukuba uwuthenge?

Consultants ezitolo ubuchwepheshe akuvamile anganika iseluleko esinengqondo, futhi ngokuvamile zimane nje vparivayut imodeli eqolo, okuyinto kuleli cala is hhayi njalo sibhekane ngokuphumelelayo imisebenzi yabo.

Hhayi ukuze overpay zomkhiqizo nezici okungafunwa, udinga okungenani umbono sakugcina yini umsebenzi kungaphansi. Ngakho namuhla ake sixoxe ngalokho kuhle kakhulu ukuba uwuthenge umzila, kuye ngokuthi yakho esikuthandayo kanye nezidingo.

Yini odinga ukuyazi umhlinzeki?

Ezinye izici isandla zincike Internet wakho wesevisi futhi izici yokugibela yakho.

Okokuqala, ucingo lwakho ISP nangendawo yokuthola ukuthi yini uhlobo WAN-port ke ukusetshenziswa. WAN - lokhu isixhumi lapho ikhebula okungukuthi axhunyiwe ngqo esetshenziselwa efulethini. Kukhona 3 kuphela izinhlobo ukuxhumana:

• ngokusebenzisa umugqa yefoni (salokhu udinga router ne-port DSL, ADSL noma VDSL);
• ozinikele isiteshi Inthanethi (i-Ethernet / FTTB);
• zesimanje fibre optic inethiwekhi (CPON, CEPON, Pon).

Futhi emakethe kukhona 3G-imizila - basuke ngokukhethekile bazivumelanisa ukusebenza Internet mobile. Uma isabelomali ivumela, ungathatha router jikelele esekela amafomethi ambalwa (isib, i-Ethernet + DSL noma i-Ethernet + 3G).

Eyesibili iphuzu - isivinini. Yikuphi okungcono ukuthenga router ukuze ebaleka Inthanethi ngokushesha? Ukuze uqale, hlola ukuthi amazinga uphiwa self umhlinzeki, futhi balinganisela ukuthi evumelana nawe. Kakade kusukela lokhu thina ukhetha imodeli ezinezici efanelekayo.

I izici lobuchwepheshe router, njalo ukhombise ngesivinini esiphezulu ukudluliswa kwedatha. Khumbula, le nombolo imele kuphela kungenzeka theory zedivayisi, ngaphandle kokuthatha ku umsindo akhawunti kanye nebanga. Empeleni, i-Internet izosebenza 2.5-3 izikhathi kancane.

Ijubane incike isignali ejwayelekile ukuthi kusekela WiFi-router:

• 802.11ac - okufana esimanjemanje kakhulu, kwakuthiwa uyakwazi ukukhulula kuze kufinyelele 1.3 Gbit / s;
• 802.11n - kwenzeka kakhulu ngokuvamile inikeza ngesivinini afika ku-600 Mbit / s;
• 802.11g - ifa ejwayelekile, okwenza zilinganiselwe izinhlobo kwakwakhe kuze kufinyelele 54 Mbit / s.

Nokho, musa ukusheshe ukuthenga entsha "fancy" router. Phela, kubalulekile, futhi amakhono imishini yakho. Abaningi yezinto zobuchwepheshe manje sisebenza nge 802.11n, ngakho ngeke bakwazi ukuba inqubo ngokushesha isignali.

Izici Key

Thina baphendukela nemingcele encike ayisekho umhlinzeki, futhi yakho siqu izintandokazi kanye nezidingo. Akunakwenzeka ukuthi okuyinto vayfay router Kungcono ukuthenga, uma kungekhona ukuba acabangele, kanjani futhi kungani ukusebenzisa kudivayisi. Yini okufanele banake?

Isibalo LAN-nezimbobo

Ngokuvamile imishini umile, okuyinto edinga esitebeleni internet uxhumano (amakhompyutha, ama-TV, aduduze nokunye. D.) Ingabe exhunywe kwi-router nge ikhebula. Lokhu kuqinisekisa isivinini, okuyinto akuxhomekile ukuphazamiseka kanye nebanga.

Ngo iningi ezivamile imizila enikeziwe 4 LAN isixhumi. Kodwa uma unayo eziningi ubuchwepheshe, kunengqondo ukukhetha imodeli ne izimbobo ezengeziwe. Ngokwesibonelo, ASUS RT-AC88U futhi TP-LINK TL-R860 uvumele kufika 8 amadivayisi nezintsha MikroTik RB2011UiAS-IN - 10.

Nakani uhlobo LAN-nezimbobo. Fast-Ethernet nezixhumi kubalwa 100 Mbit / s, kuyilapho Gigabit Ethernet inikeza ukudluliswa isivinini esiphindwe izikhathi ezingu-1 Gbit / s.

imvamisa uhla

Esinye isici esibalulekile. WiFi-imizila ongaqhuba at 2.4 noma 5 GHz. onobuhle yamuva Okuningi ukusekela kokubili iziteshi, ungasabalalisa idatha phakathi izibopho.

Ngenzenjani okudingeka uzicabangele? Okokuqala, onjani imishini uzobe exhunywe kwi-router:

• 2.4 GHz ngokufanele zokuhamba Smartphones, amaphilisi kanye nemishini ehhovisi;
• 5 GHz ihlinzeka fast and uxhumano ezinzile, Kunconywa amadivayisi ukuthi umsebenzi nge ngoyisiwula kusinda okuqukethwe - TV, set-top amabhokisi, nokunye. N.

Sicela uqaphele ukuthi akuzona zonke amagajethi bangathola isiginali at a imvamisa 5 GHz. Kodwa uma wakho efulethini emhlabeni eziningi imizila ukuthi ongakuphazamisa isibonakaliso, ukuthi lesi siteshi okungukuthi oluncamelayo. Ukushintshela imvamisa ephakeme ukwandisa ijubane ukushintshanisa kwe-data, kodwa kancane ukunciphisa enenethiwekhi engenantambo.

Lidlulisela amandla

Abathengi thukela sinake lolu khetho, kodwa kubalulekile okungaphezu theory ngesivinini esiphezulu.

Ngo kwezimali umthamo onobuhle akuvamile idlule 17 dBm. Lokhu kusho ukuthi isiginali kudivayisi ikani "break ngokusebenzisa" ezingeqi kwezingu ezimbili izindonga. Kodwa akubona bonke ngakho elula: cishe kuwo wonke amazwe, khona imingcele zomthetho phezu esiphezulu amandla ovumelekile. umbundu Upper ngoba imvamisa ka 2.4 GHz ubhekwa 20 dBm - yiziphi onobuhle iwukukhetha uma une efulethini ivulekile.

Ububanzi

Ngokuvamile ku ibhokisi nasesikhathini lobuchwepheshe imibhalo bhala ibanga, embozwe yinethiwekhi. Eceleni esibekiwe ububanzi, ngaphakathi nangaphandle ngaphandle. Kodwa uma sikhuluma onjani WiFi-router kuhle kakhulu ukuba uwuthenge, lesi sibalo isihlobo kakhulu. Ipheya obukhulu kwagcizelela izindonga kakhonkolo "ukubulala" isignali, ngisho imizila enamandla kakhulu. U-70% wona akuxhomekile zedivayisi ngokwayo, okungukuthi egunjini.

Uhlobo kanye nenani lama-antenna

Inkolelo evamile iphutha abathengi - ukucabanga ukuthi amandla antenna amaningi niyozenezelelwa ndawonye. Kodwa uma bobathathu, akusho ukuthi inethiwekhi ezosebenza izikhathi 3 phambidlana noma "iziteleka" izindonga ngaphezulu. Loku kungenteka kuphela ukwenza kube nokuhlobana enamathela ezinzile iyunifomu.

Futhi nakhu okufanele unake? Eyokuqala okungukuthi uhlobo antenna - esakhelwe noma zangaphandle. Njengoba kukhonjisiwe, edolobheni efulethini okungukuthi umehluko phakathi kwabo okungukuthi cishe imperceptible. Kodwa uma sikhuluma elikhulu ikamelo, kungcono ukhetha umuntu oyisibonelo nge zangaphandle antenna. Lokhu kuqinisekisa enamathela more uzinze, futhi, uma kunesidingo, ukuba esikhundleni saso kungene namandla kakhulu.

Ngezindlela eziningi izinga lomsebenzi we-antenna kuxhomeke kulokho chipset lisebenzisa. Ngakho-ke, enye indlela, okuyinto kuwufanele look - inzuzo. Ukwandisa uhla futhi isignali izinga, antenna ingasetshenziswa izinhlobo eziningana:

• standard - 2 DBI inzuzo;
• omnidirectional (9 DBI);
• Panel (19 DBI);
• parabolic (24 DBI).

Yikuphi router kuhle kakhulu ukuba uwuthenge? Ukudayiswa kuyinto inombolo yohlobo yanoma antenna 1 kuya ku-4 Ngoba indlu eyodwa storey noma ifulethi ezisemadolobheni ngokufanele ofanele router 2-3 antenna nge nzuzo mayelana 5 DBI. Positioning antenna desirably zibheka noma nge-engela encane komunye nomunye.

Iyatholakala-USB

Amamodeli eyodwa noma ngaphezulu-USB nezimbobo ezibizayo, kodwa ovulekile umsebenzisi a lot of izici ezengeziwe. Ngu yokuxhuma drive WiFi-router, ungakha isixazululo isitoreji sokwabelana, okuyinto Ungaxhuma wonke amadivayisi kunethiwekhi ye. Ngaphezu kwalokho, uma intambo internet izitobhi zokusebenza, ungaya ku-intanethi ngobuchwepheshe obungenawaya USB-imodemu.

"Chips 'engeziwe

abakhiqizi abaningi ukukhiqiza imizila, okuyinto ngaphezu umsebenzi wayo ophambili nosemqoka - "siyalahla" Internet - babe nezinye izici ewusizo.

3G / 4G

Ewusizo kakhulu uma isikhathi esiningi basebenza ezindaweni ezahlukahlukene, kufaka phakathi kuleli zwe. Esakhelwe ngaphakathi 3G-imodemu ikuvumela ukuba ukuxhuma kwi-Inthanethi ngokusebenzisa inethiwekhi opharetha mobile.

Futhi ikhona zingatholakala imizila ezikhethekile. Sitshele kafushane mayelana nendlela router mobile engcono ukuthenga.

Inketho esiwusizo kakhulu - isibonelo multi-indinganiso bangasebenza zonke opharetha. Ukuze ukhethe enye inethiwekhi, ngokwanele ukushintsha le-SIM noma ukushintsha idivayisi ngokusebenzisa esibonakalayo web.

Kunakeni lokho namazinga kusekelwa router. EVDO Rev.B angabakhulula kuze kube 14.7 Mbit / s, futhi UMTS / HSDPA kubhekwe ngokushesha futhi uyakwazi yokusebenza ngesivinini esingafinyelela ku-42 Mbit / s.

Uma router isetshenziswa ezindaweni ngamandla isignali enganamandla (isib ezindaweni zasemakhaya), kutuswa ukhetha idivaysi ixhunywe esinothi.

Phakathi amamodeli ethandwa kakhulu kungenziwa okukhulunywa imizila Pantech MHS291L, Novatei MiFi 6620L Rev.B, ZTE AC30.

ne-IPTV

Yikuphi router kuhle kakhulu ukuba uwuthenge? Ngo-2014, kwaba khona "indumezulu" wangempela - abantu baqala bakamalalahlengezela uthuthukise kusuka ikhebula njalo ne-IPTV. ithelevishini Digital inikeza isithombe izinga okuningi ephakeme kanye umsindo. Kulokhu, ungakwazi ukubuka noma yiziphi iziteshi ezivela emhlabeni wonke, kanye ukusetshenziswa imisebenzi eyengeziwe ezifana hlehlisa futhi ukurekhoda igiya.

Multiple zokungena

Iwusizo "kusiza!" - kungenzeka usebenzisa umzila ukudala, hhayi kanye kodwa eziningana engenantambo amanethiwekhi. Lena ngokuyinhloko kweqiniso amahhovisi kanye izakhiwo bezentengiselwano, uma kukhona isidingo ukwehlukana traffic phakathi, eyenzelwe izisebenzi nezivakashi. Ngokwesibonelo, amakhasimende ongasivimbela ukuba ezihlukahlukene imishini inethiwekhi (amakhompyutha, amaseva, r. N.).

Sesifufula amaklayenti

Uma uvame thwebula movie high quality, imidlalo kanye nokunye okuqukethwe, kunengqondo ukukhetha WiFi-router nge esakhelwe sesifufula nekhasimende lakhe. Kulokhu, router kungaba ngemuva ukulanda amafayela ezidingekayo drive exhunyiwe, esikhundleni kulayishwa ikhompyutha ngokwayo noma ikhompyutha ephathekayo.
