Umqondiso ophindayo ugubungela imigangatho engama-20 yecala leempawu

Isignali ye-elevator yemigangatho engama-20, iseti ye "elevatorophinda umqondiso” ukusombulula ingxaki yokhuseleko olupheleleyo. Ikwaxhasa iibhendi ze-NR41 kunye ne-NR42 ze-5G. Olu hloboisandisi-lizwi somqondisoiphuhliswe ngokukodwa ukugubungela i-elevator, ukuze abathengi bazele indumiso.

Uhlalutyo lweProjekthi

Ngoku imigangatho yoluntu iya isiba phezulu, kwaye ilifti iye yaba yindlela eyimfuneko yothutho. Noko ke, ilifti.ukugubungela umqondisoakonelanga, umqondiso ubuthathaka, kwaye nomqondiso ulahlekile, nto leyo eye yangcwaba imingcipheko yokhuseleko kubantu abathatha i-elevator. Ngoko ke, abasebenzi bolawulo kufuneka baphucule kwaye bakhulise ukugubungela umqondiso we-elevator ukuqinisekisa ukhuseleko lwabahlali.

Lo msebenzi ukwisakhiwo esitsha eHunan, esigubungela izinyusi ezibini ezinemigangatho engama-20 kunye nomgangatho ongaphantsi. Ngenxa yempendulo ephindaphindiweyo yomnini ukuba i-elevator ayinayo uphawu, abasebenzi bolawulo bafumana iqela likaLin Chuang ukuba lenze.ukugubungela umqondiso.

Iskimu soyilo

Sithathela ingqalelo ukuba umgangatho we-elevator unamanqanaba angama-20, kwaye ukusetyenziswa kwe "elevator signal repeater" kuyindleko kwaye iyasebenza.

I-elevator ihlukaniswe kwiisethi ezimbini zezixhobo, iyunithi yokulawula eyona nto kunye neyunithi yemoto, ngamagama alula: iyunithi yokulawula eyona nto "ikhokelela" umqondiso ovela ngaphandle ukuya kwi-elevator shaft, kunye neyunithi yemoto idlulisela umqondiso we-elevator shaft; ukuvala i-elevator yonke.

Iskimu sokwabiwa kwemveliso

I-elevatorUkuphinda uMqondisoixhasa i-2G-5G, ukunyusa umqondiso we-three-frequency, ilungele ukugubungela umqondiso we-elevator ngaphantsi kwemigangatho engama-30, ibhendi yefrikhwensi eyandisiweyo ibandakanya i-NR41 kunye ne-NR42, ngokwenene isantya senethiwekhi "5G" sikhawuleza kakhulu! Iphuhliselwe ukugutyungelwa kophawu lweelevator, xa ithe yasungulwa yanconywa ngokubanzi.

Inkqubo yokuFakela

1. Fumana indawo ngaphandle apho umthombo wesignali (ngaphezu kweegridi ezi-3) ulungile (njengomgangatho ophezulu), kwaye ufake i-antenna yokufumana iyunithi yokulawula eyintloko apha. I-eriyali eyamkelayo kufuneka ijongane nenqaba yomqondiso.

2.Sebenzisa i-eriyali yokwamkela ngaphandle kwisiphelo se-eriyali RF_IN, kunye ne-RF_OUT isiphelo seamplifier kwi-eriyali ethumela ngaphakathi. Jonga ukuba unxibelelwano luzinzile.

3.Qinisekisa ukuba onke amacandelo axhunyiwe kwaye izixhumi zikhuselekile, kunye namandla kwi-amplifier. Emva koko faka iyunithi yemoto ngendlela efanayo, kwaye umqondiso we-elevator ugcwele ngoko nangoko!

I-eriyali yokufumana ifakwe phezulu kwi-elevator.

I-eriyali yokudlulisa ifakwe ngaphakathi kwi-elevator.

Ezi zimbini zixhunyiwe kumatshini oyintloko kunye ne-feeder.

I-4.Ukubonwa kweSiginali Emva kokufakwa, isofthiwe ye-"CellularZ" isetyenziselwa kwakhona ukufumanisa ixabiso lesignali ye-elevator, kwaye ixabiso le-RSRP linyuswe ukusuka -116dBm ukuya kwi-78dBm, umphumo wokuphucula unamandla kakhulu!

I-RSRP lixabiso eliqhelekileyo lokulinganisa ukuba isibonakaliso sihamba kakuhle, ngokuqhelekileyo sithetha, sihamba kakuhle kakhulu ngaphezu kwe-80dBm, kwaye akukho intanethi ingaphantsi -110dBm.

Emva kokufaka ubuncwane be-elevator, ayikwazi ukuthetha ngokutyibilikayo kwi-elevator, kodwa kunye nemidlalo yevidiyo emfutshane, kwaye umphumo wokugubungela unconywa ngabasebenzi bolawulo loluntu! Ukuba indawo ohlala kuyo nayo inenkathazo yomqondiso, ungashiya iinkcukacha zakho zoqhagamshelwano ngasemva.
