Ngena cishe kunoma iyiphi i-basement ifoni yakho ingaphandle bese iphethini iyaziphinda: imigoqo iyaphela njengoba udlula ezitebhisini, futhi eduze kodonga olungemuva ifoni iyafuna. Kwenzeka emibhoshongweni yamahhovisi, emahhotela, emagaraji okupaka izimoto ezinkulu kanye nasezitezi eziphansi zesibhedlela ngokufanayo. Ukhonkolo, insimbi nomhlabathi ogcwele kuhlezi phakathi kwakho nombhoshongo, futhi amaza omsakazo awawathandi.
Uma umuntu ehlela i-network booster yamaphrojekthi angaphansi komhlaba, ukulungiswa ngokwako kuvame ukuba sobala. Umsebenzi wangempela ukukhetha nokulinganisa ukusetha ngendlela efanele, futhi lokho kufanele kubhekwe isikhathi eside kunalokho ikhasi lomkhiqizo elingakunikeza.
Isitudiyo – Indlu Yewayini Engaphansi Kwegumbi Eli ...
Kungani izikhala ezingaphansi komhlaba zilahlekelwa isignali ngokushesha kangaka?
Ngaphezu kwezinga lomgwaqo, ifoni yakho ivame ukuba nomugqa ocacile wokubona umbhoshongo, mhlawumbe nodonga olulodwa noma ezimbili phakathi. Ngaphansi kwezinga, isignali kufanele idlule enhlabathini, kuma-slab ekhonkrithi, kuma-rebar mesh kanye nendawo yokupaka yonke ebekwe ngaphezu kwakho. Ingqimba ngayinye iyalimaza, futhi ndawonye ingadonsa isignali yangaphandle eqinile ngokuphelele ize ifinyelele cishe kulutho.
Izizathu zokuncipha kwesignali ye-booster esitezi esingaphansi komhlaba
Imvamisa nayo ibalulekile. Ama-band aphansi, cishe angu-700 kuya ku-900 MHz, ahamba ibanga elide futhi adlule ezindongeni kangcono. Ama-band aphezulu, ububanzi be-1800, 2100 kanye ne-2600 MHz obusetshenziswa kakhulu amanethiwekhi amaningi ukuze athole amandla, aphelelwa yisikhathi ngokushesha. Yingakho igumbi elingaphansi kwebanga lingagcina ucingo kwelinye ibhendi kodwa lilahlekelwe ngokuphelele kwelinye, futhi ibhokisi lebhendi elilodwa alivamile ukwanelisa isayithi lesimanje.
Esinye isignali siyavuza. Ama-lifti, iminyango ye-ramp kanye nezikhala zomoya ziphethe ingxenye yazo, okuvame ukwanele ukuthi i-antenna yangaphandle isebenze ngayo. Izindaba ezinhle kubafaki. Kodwa futhi kusho ukuthi uhlelo lwephansi lodwa ngeke lukutshele okuningi. Ukufundwa okusheshayo ngocingo noma ngemitha efanele endaweni yabanikeli kunquma ukuthi yimiphi imishini ezosebenza ngempela.
Isiphindaphindo sesignali yeselula ye-KW20N esinebhendi ephindwe kathathu
Qala ngamanethiwekhi, hhayi ihadiwe
Amaza omoya aseNigeria abiwa yi-MTN, i-Airtel, i-Glo kanye ne-9mobile. EKenya, i-Safaricom kanye ne-Airtel zithwala iningi lethrafikhi. Zonke zisebenzisa izinsizakalo zazo zansuku zonke ngokusabalala okujwayelekile kwamaza: i-900 MHz yamanethiwekhi amadala kanye nokungena okungcono kwesakhiwo, i-1800 kanye ne-2100 MHz yezendlalelo ze-3G kanye ne-4G ezisingatha idatha eningi, kanye nengxenye ekhulayo ye-2600 MHz emadolobheni amakhulu. I-Kenya iphinde igcine ingxenye yamandla ayo e-4G ebhendini le-800 MHz.

Lokho kusakazeka kuyisihlungi sakho sokuqala lapho uthenga. Iyunithi ekhulisa ibhendi eyodwa ingase isindise izingcingo kunkampani eyodwa futhi ishiye ezinye zifile, okuyisikhalazo esivamile ezakhiweni lapho abasebenzi behlala khona kumanethiwekhi ahlukene. Funa imodeli yamabhendi amaningi ehlanganisa okungenani ama-900, 1800 kanye nama-2100 MHz, bese uqinisekisa ukuthi iphatha ama-800 MHz uma isayithi laseKenya liyidinga.
Okulindelwe ukuthi kuqale kusenesikhathi. I-5G kuwo womabili la mazwe ikakhulukazi iyisevisi ye-3500 MHz egxile ezikhungweni zedolobha, futhi iningi le-booster hardware lima ku-2600 MHz. Amasignali kuleyo mvamisa awafiki kangako ezindlini ezingaphansi komhlaba. Uma iklayenti liphikelela ku-5G ngaphansi kwebanga, phatha njengengxoxo ehlukile futhi ebiza kakhulu, akuyona into ibhokisi elilodwa elingayithembisa.
Kala isignali yomnikeli ngaphambi kwanoma yini enye
Amakhathalogi athanda izibalo zokumboza. Empeleni, inombolo isho okuthile kuphela uma wazi isignali yangaphandle osebenza ngayo. Ukufundwa kwe--60 dBm ophahleni kwenza kube lula ukukhulisa i-booster. Ku--100 dBm noma okubi nakakhulu, kuncane okusele kokukhulisa, kungakhathaliseki ukuthi isitikha sithini.
Emisebenzini engaphansi komhlaba, i-antenna yomnikelo ivame ukuba phezu kophahla noma odongeni lwangaphandle olubheke umbhoshongo oseduze. Ama-shaft e-elevator kanye nezimbobo ze-ramp ziyavuza, futhi lokho kuvuza kuvame ukwanele ukusebenza ngakho. Ungathatha ukufundwa okungenangqondo ngesikrini sokuhlola insimu yocingo noma imitha engabizi ngaphambi kokuchitha imali emishinini, futhi leyo nombolo eyodwa inquma ubukhulu besistimu oyidingayo. Izimo zendawo ziyahlukahluka kakhulu: iphansi lehhovisi eliyi-drywall aliziphathi njenge-concrete mall parkade, ngakho-ke kala isakhiwo sangempela kunokuqagela kusuka kwesinye esifanayo kamuva.
Qondanisa ikilasi lesistimu nomsebenzi
A uhlelo lokuqinisa isignali yeselulainezingxenye ezintathu: i-antenna yangaphandle, i-amplifier, kanye nama-antenna angaphakathi asakaza isignali egumbini lonke. Ngaphandle kwalokho, imisebenzi engaphansi komhlaba kulesi sifunda ivame ukuwela ezilinganisweni ezimbili.
Izindawo ezincane zezentengiselwano, isitezi esingaphansi sehhovisi, iphansi lekliniki, noma igumbi lokudayisa elisebenzisa ikhawunta ye-PoS noma i-M-Pesa kuze kube yilapho isikhathi siphela, ngokuvamile kusebenza kahle ngekhithi ye-tri-band noma ye-five-band enikeza i-gain engu-55 kuya ku-65 dB engu-55 kuya ku-65 dB.

Amaphrojekthi amakhulu, indawo yokupaka ngaphansi komhlaba yezitolo ezinkulu, izitezi ezingaphansi kwehhotela, noma isisekelo sebhange esinezitezi eziningi, kudinga indawo yokupaka.isikhuthazi sesignali yamandlaenomkhiqizo ophezulu kanye nama-antenna amaningana angaphakathi abekwe kulo lonke indawo. Lapho i-antenna yomnikeli iphetha ngekhebula elide elisuka endaweni elidinga ukumbozwa, i-fiber-optic repeater igwema ukulahlekelwa okulethwa yi-coax run ende.
uhlelo lokuqinisa isignali yeselula
Into eyodwa okufanele uyazi: inzuzo eyengeziwe ayingcono ngokuzenzakalelayo. Amandla okukhipha kanye nokubekwa kwe-antenna kwenza umsebenzi wangempela. Iyunithi ephakathi nendawo efakwe ngekhebula elihle kanye ne-antenna enikelwe kahle izodlula enamandla eboshwe ndawonye ngekhebula elincane kanye ne-antenna efihliwe.
Uma ulinganisa umsebenzi ongaphansi komhlaba eLagos noma eNairobi, noma wakha uhlu lwesitoko lwanoma iyiphi imakethe, sithumelele izisekelo: uhlobo lwesakhiwo, indawo yephansi, izinkampani okufanele uzimboze, kanye nokufundwa kwesignali yabanikeli uma unayo. Uzothola uhlu lwemishini, ukwakheka okungahleliwe, kanye nempendulo eqondile mayelana nama-band kanye nokuvunyelwa.
