Ngomhla zi-2 kuNov 2019, ithimba le-IWAVE ngesimemo somnyango wezomlilo esifundazweni saseFujian, lathatha uchungechunge lokuzivocavoca ehlathini ukuze lihlole ukusebenza kohlelo lokuxhumana oluphuthumayo lwe-4G-LTE.Leli fayela liyisiphetho esifushane senqubo yokuzivocavoca.
1.Ingemuva
Lapho abezicishamlilo bethola isixwayiso sokuthi umlilo wehlathi uboniwe, wonke umuntu emnyangweni kudingeka aphendule ngokushesha nangendlela ewujuqu.Kuwumjaho ophikisana newashi ngoba ukonga isikhathi kusindisa izimpilo.Phakathi naleyo mizuzu yokuqala ebalulekile, abaphenduli bokuqala badinga uhlelo lokuxhumana olusetshenziswa ngokushesha kodwa oluthuthukisiwe oluxhuma nazo zonke izinsiza zabantu.Futhi isistimu idinga ukusekela kunethiwekhi engenazintambo ezimele, ebanzi nezinzile evumela izwi lesikhathi sangempela, ividiyo kanye nokudluliswa kwedatha ngaphandle kokuncika kunoma yiziphi izinsiza zentengiso.
Ngokumenywa komnyango wezomlilo weSifundazwe sase-Fujian, i-IWAVE ihlele ochwepheshe bezokuxhumana, ochwepheshe bokuvikela amahlathi, kanye nesazi samahlathi esiphezulu ukuze benze uchungechunge lwezivivinyo mayelana nokukhipha ngokushesha inethiwekhi yangasese ye-4G TD-LTE emahlathini.
2.Izimo Zendawo
Indawo: Jiulongling Forest Farm, Longhai, Zhangzhou, Fujian, China
Indawo: Indawo enamagquma ogwini
Ukuphakama: 25-540.7meters
I-Slope: 20-30degree
Ubukhulu bengqimba yenhlabathi: 40-100cm
3.Okuqukethwe Ukuzivocavoca
Iizivivinyohlose ukuqinisekisa:
① Ikhono lokudlulisela le-NLOS ehlathini eliminyene
② Ukufakwa kwenethiwekhi eduze kwe-firebreak
③ Ukusebenza kohlelo lokuxhumana lwezehlakalo eziphuthumayo ehlathini.
3.1.Ukuzivocavocayokudluliselwa kwe-NLOS ku-dense fi-orest
Ukwenza amasosha noma abaphenduli bokuqala baxhunywe ngaphandle kwentambo emahlathini aminyene nasezindaweni zemvelo ezinokhahlo, kuzonikeza izinzuzo ezimbalwa ezimweni eziphuthumayo.
Kulokhu kuhlola sizokwenza imishini yokuxhumana engenantambo isebenze ezimeni ezimbi kakhulu ukuze iqinisekise ikhono layo le-NLOS.
Ukuthunyelwa
Faka uhlelo oluphathekayo oluphuthumayo (Patron-P10) endaweni enehlathi eliyinkimbinkimbi neliminyene (ubude: 117.705754, latitude: 24.352767)
Imvamisa Emaphakathi: 586Mhz
Umkhawulokudonsa: 10Mhz
Amandla e-RF: 10watts
Okwesibili, abantu abahlolwayo bathathe i-CPE ye-manpack kanye ne-trunking handset behamba ngokukhululeka ehlathini.Ngesikhathi sokuhamba, ukuxhumana kwevidiyo nezwi kudinga ukuqhubeka.
Umphumela Wokuhlola
Ukudluliswa kwevidiyo kanye nokuxhumana kwezwi kwagcinwa ngesikhathi sonke sokuhamba kwaze kwaba yilapho i-CPE ilahlekelwa ukuxhumana no-patron-P10.Njengoba kukhonjisiwe esithombeni esingenhla (Umbala Oluhlaza usho ukuthi ividiyo nezwi kubushelelezi).
I-Trunking Handset
Lapho umhloli ehamba ibanga elingama-628meters ukusuka endaweni ye-patron-p10, i-handset yalahlekelwa ukuxhumana no-patron-p10.Bese i-handset ixhuma ne-CPE nge-Wi-Fi futhi ukuxhumana kwezwi nevidiyo ngesikhathi sangempela kuphinde kwalulama.
I-Manpack CPE
Ngenkathi umhloli ewela umthambeka ophezulu, i-CPE ilahlekelwe ukuxhumana.Ngalesi sikhathi amandla esignali ayengu -98dBm (Lapho umhloli emi phezulu emthambekeni, izinga ledatha lalingu-10Mbps)
3.2.Ukuzivocavoca ukuze uthole inethiwekhi eduze kwe-firebreak ehlathini
I-Firebreak iyigebe ezitshalweni elisebenza njengesithiyo sokunciphisa noma ukumisa ukuqhubeka komlilo wehlathi.Futhi izinqamuli zomlilo zisebenza njengemigwaqo yokugada ezintabeni nokuvikela amahlathi, ukuqagela amandla okucisha umlilo, izinto zokucisha umlilo, ukudla, nokunye ukulethwa kwempahla yokweseka, edlala indima ebalulekile ekucimeni umlilo kwamahlathi.
Ukuze ubhekane nesenzakalo esiphuthumayo endaweni yehlathi, ukumboza isicishamlilo ngenethiwekhi ezinzile futhi enesivinini esikhulu kuwumsebenzi oyinselele.Endaweni yokuhlola eboniswe esithombeni esingenhla, ithimba le-IWAVE lizosebenzisa i-Patron-P10 ukumboza i-firebreak ngenethiwekhi yangasese ye-4G-LTE ukuze kube nokuxhumana okuzinzile.
Ukuthunyelwa
Khipha ngokushesha isiteshi sesisekelo esihlanganisiwe esiphathekayo (Patron-P10), konke ukuthunyelwa kuthathe imizuzu eyi-15.
Imvamisa Emaphakathi: 586Mhz
Umkhawulokudonsa: 10Mhz
Amandla e-RF: 10watts
Khona-ke umhloli wathatha i-CPE futhi i-trunking handset yahamba eduze komlilo
Hlola Umphumela
Umhloli onehendisethi ne-CPE ugcine ividiyo yesikhathi sangempela nokuxhumana kwezwi nabantu endaweni yesiteshi esihlanganisiwe esiphathwayo (Yenza njengomyalo wesimo esiphuthumayo nesikhungo sokuthumela).
Njengoba kuboniswe esithombeni esingezansi, indlela yokuhamba eluhlaza isho ukuthi ividiyo nezwi kubushelelezi futhi kucacile.
Ngesikhathi umhloli ekhuphuka eduze kwesivimbamlilo futhi ehamba phezu kwentaba, ukuxhumana kwalahleka.Ngenxa yokuthi igquma liphakeme ngamamitha angu-200 kunendawo yesiteshi, ngakho-ke amasiginali avinjiwe futhi alahlekelwa ukuxhumana.
Ngenkathi umhloli ehla ngesinqamuli-mlilo, uxhumo lulahlekile ekupheleni kwesinqamulimlilo.Leyo ndawo iphansi ngamamitha angama-90 kunendawo yokuphakelwa kwesiteshi.
Kulokhu kuvivinya okubili, asizange sikhiphe uthi lwesistimu yezokuxhumana eziphuthumayo endaweni ephakeme njengesibonelo sibeke uthi phezu kwemoto yokuxhumana yezimo eziphuthumayo.Ngesikhathi sokuzijwayeza kwangempela, uma sibeka ithikithi phezulu, ibanga lizoba lide kakhulu.
4.Imikhiqizo Ehilelekile
I-Manpack CPE Yokuxhumana Kwebanga Elide
I-Trunking Handset
