mutengo wekusimudzira masaini enharembozha

I. Chii chinonzi reverse interference yesignal amplifier kune base station?

Mumapurojekiti asina simba ekuvhara masaini, pfungwa inoshanda ye mobile signal amplifier (repeater) ndeyekugamuchira masaini kubva kunzvimbo dzekunze, kuawedzera, uye kuaendesa kune network yemukati. Zvakanaka, inofanira kungowedzera masaini anodiwa mukati, pasina kukonzera kukanganiswa kwekunze kwenzvimbo dzekunze.

                                                                                                           chinowedzera network yenharembozha yehofisi

Zvisinei, kana michina yacho isina kugadzirwa zvakanaka kana kuti antenna layout yacho isiriyo, amplifier inogona kudzosera chiratidzo chemukati chakakwidziridzwa ndokuchidzosera kuchiteshi chepasi, zvichikonzera kuti ruzha rurambe ruchienderera mberi uye kuwedzera ruzha rwechiteshi chepasi. Migumisiro yacho inosanganisira kuoma kwemafoni ari pedyo kubatana nechiteshi chepasi, kuderera kwekumhanya kwenetwork, uye kudonhedzwa kwemafoni; muzviitiko zvakakomba, zvinogona kukanganisa mashandiro echiteshi chepasi chesero, zvichiita kuti mushandi aongorore uye ade kuti michina yacho ibviswe.

Cherechedza: Maamplifier efoni haakonzeri kukanganiswa. Nemichina inoenderana nezvinodiwa uye kuiswa uye kugadziriswa kwakakodzera, kukanganiswa kwechiteshi chepasi kunogona kudzivirirwa zvachose.

2. Zvikonzero zvina zvikuru zvinokonzera kukanganiswa kwechiteshi chepasi

A. Kusakwana Kwekuparadzanisa MaAntenna Ari Kutumira Neanogamuchira (Anowanzoonekwa)

Kusakwana kwekuparadzanisa pakati peantenna yekunze inogamuchira chiratidzo chebase station neantenna inotumira mukati kunoita kuti chiratidzo chibude mushure mekuwedzerwa mukati meimba, chichidzokera kuantenna yekunze. Chiratidzo chinotenderera uye chinowedzera pakati peantenna mbiri, zvichikonzera kuzvizunguza mumidziyo. Chiratidzo ichi chinozvizunguza chinodzokera kumashure kuenda kubase station, zvichiwedzera zvakananga ruzha rwebase station uye zvichikonzera kupindirana.

Mapurojekiti mazhinji ekuvaka panzvimbo iyi anotarisa chete pakusimba kwemasaini emukati meimba, achiregeredza nzvimbo yeantenna uye kurongeka kwayo. Mapurojekiti edzimba dzekugara pasi nedzimba dzisina kuvharwa nemasaini zvishoma inyaya dzine njodzi huru dzedambudziko iri.

                                                                                                                           sisitimu yemhinduro yechiratidzo isina simba

B. Gain Set Yakanyanya Kukwira, Simba Rekubuda Rinopfuura Miganhu

Mamwe mainjiniya, vachitsvaga simba rakazara remasaini emukati, vanowedzera zvakananga kuwedzera kweamplifier yechiratidzo chefoni. Kunze, chiratidzo chechiteshi chepasi chatove chakanaka; kuwedzera kwakakosha kwechiratidzo kunoremedza chiratidzo cheuplink. Kuwedzera kwakawandisa kweamplifier yeuplink neanowanzo dzokorora mafoni kunogonawo "kukunda" base station, zvichikonzera kukanganiswa kwenharaunda yese yakapoteredza.

Mafungiro Asiriwo: Kuwedzera kwakanyanya hakusi nani nguva dzose, uye chiratidzo chakazara chemukati hachirevi kuti kushanda kuri nani.IyoAGC/MGCGain inofanira kugadziriswa nemazvo zvichienderana nesimba rechiratidzo chemupi panzvimbo iyi. Mhando dzese dzeLintratek Technology dzemarepeater ekutengeserana dzakashongedzerwa neAGC automatic gain control, iyo inodzikisa otomatiki amplification yakawandisa uye inoderedza njodzi yekukanganiswa kubva pakukanganisa kwevanhu panguva yekugadzirisa.

zvigadzirwa zvekusimbisa nharembozha zvekumaruwa

C. Kusarudzwa Kwechinosimudzira Masaini Asiriwo: Kusawirirana Pakati Pemamiriro Enzvimbo Nemabhendi Ekushandisa Frequency

Semuenzaniso, amplifier yemagetsi inofambiswa nemabhandi mashanu yakasarudzwa zvisina kujeka apo mabhendi maviri chete emagetsi asina simba ekuvhara masaini aidiwa panzvimbo yacho. Mune mamwe mabhendi emagetsi enzvimbo yemagetsi airatidza masaini emagetsi, michina yacho yakaramba ichiita amplification ine simba guru pamabhendi iwayo, zvichikonzera kukwira kwemagetsi uye kukanganiswa kwenzvimbo dzemagetsi. Uyezve, mamwe mapurojekiti aishandisa ma repeater asina kusimbiswa, asina certification, asina kushanda zvakanaka uye asina kukwana kudzvinyirirwa kwekunze kwebhandi, zvichigadzira masaini enhema aikanganisa nzvimbo dzemagetsi dzakapoteredza.

3. Ungadzivisa sei kukanganiswa kwechiteshi chepasi pachine nguva?

A. Koshesa kupatsanurwa kweantenna

Iva nechokwadi chekuti nzvimbo dziri pakati pemaantenna ekunze neemukati meimba. Nyatsoteerera kutariswa kweantenna; masaini eantenna emukati haafanire kudzoserwa kumashure kumaantenna ekunze kudzivirira kuzvitenderedza.

B. Gadzirisa purofiti nenzira yakakodzera, uchiisa AGC (Automatic Gain Control) pamberi.

Kana paine kuvharwa kwemasaini kusina simba, usatsvaga ma "full bar" mukati memba usingafungi. Isa AGC inogonesa. Mazhinji ema "commercial mobile signal amplifiers" eLinchuang Technology anotsigira ma "dual modes" eAGC/MGC, achienderana nemamiriro akasiyana-siyana akaomarara akadai sema "tunnels", ma "villas", ma "basement", uye mafekitori.

C. Zvigadzirwa zvakasarudzwa zvinofanirwa kuenderana nemabhendi chaiwo efrequency echiteshi chepasi panzvimbo yacho.

Ita ongororo panzvimbo kuti usimbise mabhendi chaiwo emafrequency ari kushandiswa munharaunda, sarudza zvigadzirwa zvinoenderana nezvinodiwa, uye dzivisa kuungana mabhendi akawanda emafrequency usingazivi; iva nechokwadi chekuti zvigadzirwa zvinotevedzera mitemo uye zvine chitupa, uye ramba michina isina mwero kana yakagadziriswa.

D. Iva nechokwadi chekuti matekiniki ekuvaka akakodzera

Simbisa zvinobatanidza zvemagetsi uye iva nechokwadi chekuti mvura haipindi; verenga kurasikirwa kwemagetsi pachine nguva kuti usadonhedze masaini; dzivisa kuisa maantenna ekunze zvakananga pakatarisana nenzvimbo dzemagetsi.

E. Ongororo mushure mekupedza inodiwa.

Mushure mekunge chirongwa chapera, tarisa mamiriro ealarm yemuchina. Hapana alarm yechiedza chitsvuku inozvikonzera; panguva imwe chete, tarisa network yefoni yakapoteredza. Kana pasina kunonoka kusingatarisirwi, chirongwa chinoonekwa sechapera.

                                                                                                purojekiti yekuwedzera simba rekuvaka mahofisi

4, Matanho Ekukurumidza Ekugadzirisa Dambudziko Rekukanganisa Nzvimbo Yepasi

1.）Deredza kukwira kwe amplifier yesignali yefoni uye tarisa kana kupindira kwadzikira;

2.） Tarisa nzvimbo uye kurongeka kwemaantenna maviri uye wedzera kupatsanurwa;

3.） Tarisa tambo yekudyara nezvinobatanidza kuti hazvina kugadzikana kana kukuvara;

4. （Tarisa maalarm ekuzvitenderedza. Kana kuzvitenderedza kukaitika, kunofanira kugadziriswa nekukasika;

5.）Kana uchishandisa MGC mode nemaoko, chinja kuenda kuAGC automatic gain control mode kuti uedze.
