Ngomhla we-2 ngo-Nov 2019, iqela le-IWAVE kwisimemo sesebe lomlilo kwiPhondo laseFujian, lathatha uchungechunge lokuzilolonga ehlathini ukuvavanya inkqubo yonxibelelwano yomyalelo we-4G-LTE engxamisekileyo.Le fayile sisiphelo esifutshane senkqubo yokusebenza.
1.Imvelaphi
Xa isebe lomlilo lifumana isilumkiso sokuba kubonwe umlilo wehlathi, wonke umntu kwisebe kufuneka aphendule ngokukhawuleza nangokuqinisekileyo.Lugqatso oluchasene newotshi kuba ukonga ixesha kusindisa ubomi.Ngexesha laloo mizuzu yokuqala ebalulekileyo, abaphenduli bokuqala badinga inkqubo yonxibelelwano ekhutshwe ngokukhawuleza kodwa ehamba phambili edibanisa nabo bonke abantu.Kwaye inkqubo kufuneka isekelwe kwinethiwekhi ezimeleyo, i-broadband kunye ne-stable wireless evumela ukuba ixesha langempela lelizwi, ividiyo kunye nokuhanjiswa kwedatha ngaphandle kokuxhomekeka kuyo nayiphi na imithombo yorhwebo.
Ngesimemo seSebe lezoMlilo lePhondo laseFujian, i-IWAVE iququzelele iingcali zonxibelelwano, iingcali zokukhusela amahlathi, kunye nomphathi omkhulu wehlathi ukuba aqhube uchungechunge lwe-drills malunga nokuhambisa ngokukhawuleza inethiwekhi yangasese ye-4G TD-LTE emahlathini.
2.Iimeko zeJografi
Indawo: Jiulongling Forest Farm, Longhai, Zhangzhou, Fujian, China
Umhlaba: Indawo eselunxwemeni enenduli
Ukuphakama: 25-540.7meters
Ukuthambeka: 20-30degree
Ubukhulu bomaleko womhlaba: 40-100cm
3.Imixholo yoMthambo
Iimithambojonga ukuqinisekisa:
① Isakhono sothumelo lwe-NLOS kwihlathi elishinyeneyo
② Ukhuseleko lwenethiwekhi ecaleni komlilo
③ Ukusebenza kwenkqubo yonxibelelwano kwiziganeko ezingxamisekileyo ehlathini.
3.1.Yenza umthamboyosasazo lwe-NLOS kwindawo exineneyo forest
Ukwenza amajoni okanye abaphenduli bokuqala badityaniswe ngaphandle kwamacingo kumahlathi ashinyeneyo kunye neendawo ezingqongileyo ezinobunzima, ziya kubonelela ngeenzuzo ezininzi kwiimeko ezingxamisekileyo.
Kolu vavanyo siya kwenza isixhobo sonxibelelwano esingenazingcingo sisebenze kwiimeko ezimandundu ukuze siqinisekise isakhono saso se-NLOS.
Ukusasazwa
Hambisa inkqubo yongxamiseko ephathwayo (Patron-P10) kwindawo enetyholo elinzima nelixineneyo (ubude: 117.705754, ubude: 24.352767)
Izanziso esembindini: 586Mhz
Ububanzi: 10Mhz
Amandla eRF: 10watts
Okwesibini, abantu abavavanyayo bathathe i-CPE ye-manpack kunye ne-trunking handset bahamba ngokukhululekileyo ehlathini.Ngexesha lokuhamba, unxibelelwano lwevidiyo kunye nelizwi kufuneka luqhubeke.
Iziphumo zovavanyo
Ukuhanjiswa kwevidiyo kunye nokunxibelelana kwelizwi kwagcinwa ngexesha lokuhamba lonke kwaze kwaba yilapho i-CPE ilahlekelwa uxhulumaniso kunye nomxhasi-P10.Njengoko kubonisiwe kulo mfanekiso ungasentla (Umbala oluhlaza uthetha ukuba ividiyo kunye nelizwi zigudile).
Trunking Handset
Xa umvavanyi wahamba kwi-628meters kude nomxhasi-p10 indawo, i-handset yaphulukana nonxibelelwano kunye nomxhasi-p10.Emva koko i-handset iqhagamshela neCPE nge-Wi-Fi kunye nexesha lokwenyani lonxibelelwano lwelizwi kunye nevidiyo lubuyiselwe njengesiqhelo.
Manpack CPE
Xa umhloli enqumla ithambeka eliphezulu, i-CPE yaphulukana nonxibelelwano.Ngeli xesha amandla omqondiso ayeyi-98dBm (Xa umhloli wema phezulu kwithambeka, izinga ledatha laliyi-10Mbps)
3.2.Yenza umthambo yokhuselo lweNethiwekhi ecaleni komlilo ehlathini
I-Firebreak sisikhewu kwizityalo esisebenza njengesithintelo ukucotha okanye ukumisa inkqubela phambili yomlilo wehlathi.Kwaye i-firebreaks isebenza njengeendlela zokujikeleza intaba kunye nokukhuselwa kwehlathi, ukubonakaliswa kwamandla omlilo, izixhobo zokucima umlilo, ukutya, kunye nezinye izinto zenkxaso yokunikezelwa kwezixhobo, ezidlala indima ebalulekileyo ekucimeni umlilo kwamahlathi.
Ukuphendula kwisiganeko esiphuthumayo kwindawo yehlathi, ukugubungela i-firebreak kunye nenethiwekhi ezinzile kunye nesantya esiphezulu ngumsebenzi onzima.Kwindawo yokuvavanya eboniswe kumfanekiso ongentla, iqela le-IWAVE liya kusebenzisa i-Patron-P10 i-coverbreak ye-firebreak kunye ne-4G-LTE inethiwekhi yangasese yonxibelelwano oluzinzile.
Ukusasazwa
Ukuhambisa ngokukhawuleza isikhululo esisisiseko esiphathwayo esidibeneyo (Patron-P10), yonke i-deployment ithathe i-15minutes.
Izanziso esembindini: 586Mhz
Ububanzi: 10Mhz
Amandla eRF: 10watts
Emva koko umvavanyi wathatha i-CPE kunye ne-trunking handset wahamba ecaleni kwesithinteli-mlilo
Uvavanyo Isiphumo
Umvavanyi kunye ne-handset kunye ne-CPE igcine ixesha langempela levidiyo kunye nonxibelelwano lwezwi kunye nabantu kwindawo ephathekayo edibeneyo yesikhululo sesikhululo (Yenza njengomyalelo ongxamisekileyo kunye neziko lokuhambisa).
Njengoko kuboniswe kumfanekiso ongezantsi, indlela yokuhamba eluhlaza ithetha ukuba ividiyo kunye nezwi zihamba kakuhle kwaye zicacile.
Xa umvavanyi wenyuka ecaleni kwesithinteli-mlilo waza wahamba phezu kwenduli, unxibelelwano lwalahleka.Ngenxa yokuba induli iphezulu nge-200meters kunendawo yesikhululo esisisiseko, ngoko ke imiqondiso yayivaliwe kwaye yaphulukana nonxibelelwano.
Xa umvavanyi wehla kwisithinteli-mlilo, uqhagamshelo lulahlekile ekupheleni kwesithinteli-mlilo.Loo ndawo ingaphantsi ngeemitha ezingama-90 kunendawo yokusasazwa kwesikhululo.
Kolu phando lumbini, asizange sibeke i-eriyali yenkqubo yonxibelelwano olungxamisekileyo kwindawo ephezulu umzekelo ukubeka i-eriyali phezu kwesithuthi sonxibelelwano olungxamisekileyo.Ngexesha lokuziqhelanisa, ukuba sibeka i-eriyali phezulu, umgama uya kuba mde kakhulu.
