Ubuchwepheshe Basemuva
Ukuxhumana kwamanje kukhula kubaluleke kakhulu ezinhlelweni zasolwandle.Ukugcina ukuxhumana nokuxhumana olwandle kuvumela imikhumbi ukuthi ihambe ngokuphepha futhi ihambe inselele enkulu.
I-IWAVE 4G LTE Private Network Solutioningase ixazulule le nkinga ngokuhlinzeka ngenethiwekhi ezinzile, enesivinini esikhulu, futhi evikelekile emkhunjini.
Masifunde ukuthi uhlelo lusiza kanjani ngezansi.
1. Isikhathi sokuhlola: 2018.04.15
2. Injongo yokuhlola:
• Ukuhlolwa kokusebenza kwe-TD-LTE Wireless network network yangasese ezindaweni zasolwandle
• Ukuqinisekisa ukumbozwa okungenantambo kwesiteshi esihlanganisiwe (PATRON - A10) e-Ocean
• Ubudlelwano phakathi kwebanga lokumboza okungenantambo nobude bokufakwa kwesiteshi senethiwekhi yangasese (PATRON - A10).
• Ingakanani izinga lokudawuniloda kwamatheminali ahambayo ebhodini lapho isiteshi esiyisisekelo sisatshalaliswa emoyeni ngebhaluni le-helium?
• Ibhaluni le-helium lisebenzisa isivinini senethiwekhi yetheminali ephathwayo yesiteshi esiyisisekelo emoyeni.
• Uma uthi lwesiteshi sesisekelo lushwibeka esibhakabhakeni kanye nebhaluni, umthelela wothi lwesiteshi esiyisisekelo ekumbozweni okungenantambo kuyaqinisekiswa.
3. Izisetshenziswa Ekuhloleni:

Setha Isistimu Yokuhlola Ephelele
1,Ukufaka i-Base Station
I Inethiwekhi yangasese ye-LTE yonke esiteshini esisodwa kufakwa ibhaluni le-helium eliqhele ngamakhilomitha angu-4 ukusuka ogwini.Ukuphakama kwebhaluni le-helium kwakungamamitha angu-500.Kodwa kulokhu kuhlolwa, ukuphakama kwayo kwangempela kumayelana ne-150m.
Ukufakwa kwe-antenna eqondisayo ebhaluni kuboniswa ku-FIG.2.
I-engeli evundlile ye-lobe eyinhloko ibheke phezu kolwandle.I-Pan-Tilt ingalungisa ngokushesha i-engeli evundlile ye-antenna ukuze kuqinisekiswe ukumbozwa kwesiginali kanye nendawo.
2,Ukucushwa Kwenethiwekhi
Iziteshi eziyisisekelo ze-LTE ezingenazintambo zonke-in-one (Patron — A10) kumabhaluni zixhunywe kunethiwekhi ye-fiber optic ngezintambo ze-Ethernet, izintambo ze-fiber optic, ama-transceiver e-fiber optic, nerutha A. Okwamanje, ixhunywe kuseva ye-FTP (ikhompyutha ephathekayo ) ngokusebenzisa irutha engenantambo B.
3. UkuthunyelwaI-10watts CPE (Knight-V10)abagibele
I-CPE (Knight-V10) igibele esikebheni sokudoba futhi uthi lubekwe phezu kwekhebhu.I-antenna eyinhloko ifakwe kumamitha angu-4.5 ukusuka ezingeni lolwandle kanti ithiyo yesibili ingamamitha angu-3.5 ukusuka ezingeni lolwandle.Ibanga phakathi kwezimpondo ezimbili licishe libe ngamamitha angu-1.8.
Ikhompyutha ephathekayo emkhunjini ihlobene ne-CPE ngentambo yenethiwekhi futhi ihlobene neseva ye-FTP ekude nge-CPE.Isofthiwe ye-FPT yekhompuyutha ephathekayo kanye neseva ye-FTP ekude zisetshenziswa ndawonye ekuhloleni ukulanda kwe-FTP.Ngaleso sikhathi, ithuluzi lezibalo zethrafikhi elisebenza kukhompuyutha ephathekayo lingarekhoda ithrafikhi ye-inthanethi kanye nethrafikhi ngesikhathi sangempela.Abanye abahloli basebenzisa omakhalekhukhwini noma amaphedi ukuze baxhume ku-WLAN embozwe yi-CPE ukuze bahlole i-inthanethi ekhabetheni, njengokubuka imuvi eku-inthanethi noma ukwenza ikholi yevidiyo ukuhlola isivinini se-inthanethi.
Ukucushwa kwe-Base Station
| Imvamisa yesikhungo: 575Mhz |
| Umkhawulokudonsa: 10Mhz |
| Amandla angenantambo: 2 * 39.8 dbm |
| Isilinganiso esikhethekile sozimele omncane: 2:5 |
| I-NC: ilungiselelwe njenge-8 |
| I-Antenna SWR: i-antenna eyinhloko 1.17, i-antenna eyi-axiliary 1.20 |
Inqubo yokuhlola
Ukuqala Kokuhlola
Ngo-Ephreli 13, 15:33, isikebhe sokudoba sasihamba, futhi ngo-17: 26 ngosuku olufanayo, ibhaluni laphakanyiswa laba ukuphakama okungamamitha angu-150 futhi lazuliswa phezulu.Khona-ke, i-CPE ixhunywe ngokungenantambo esiteshini sesisekelo, futhi ngalesi sikhathi, isikebhe sokudoba sikude nesiteshi esingu-33km.
1,Hlola Okuqukethwe
I-laptop emkhunjini inokulandwa kwe-FPT, futhi usayizi wefayela eliqondiwe ngu-30G.Isofthiwe efakwe ngaphambilini ye-BWM irekhoda ithrafikhi ye-inthanethi yesikhathi sangempela futhi irekhoda imininingwane ye-GPS ngesikhathi sangempela ngomakhalekhukhwini.
Abanye abasebenzi abasesikebheni sokudoba bangena ku-inthanethi nge-WIFI, babukele amavidiyo aku-inthanethi futhi benze ikholi yevidiyo.Ividiyo eku-inthanethi iyashelela, futhi izwi lekholi yevidiyo licacile.Isivivinyo sonke sibe ngu-33km - 57.5 km.
2,Ithebula lokurekhoda lokuhlola
Ngesikhathi sokuhlola, izakhi zokugcwalisa ku-GPS yerekhodi izixhumanisi, amandla esignali ye-CPE, isilinganiso sokulanda esimaphakathi se-FTP, nolunye ulwazi ngesikhathi sangempela.Ithebula lerekhodi ledatha limi kanje (inani lebanga ibanga phakathi komkhumbi nogu, inani lesilinganiso sokulanda izinga lokulanda lerekhodi lesofthiwe ye-BWM).
| Ibanga (km) | 32.4 | 34.2 | 36 | 37.8 | 39.6 | 41.4 | 43.2 | 45 | 46.8 | 48.6 | 50.4 | 52.2 | 54 | 55.8 |
| Amandla Esiginali (dbm) | -85 | -83 | -83 | -84 | -85 | -83 | -83 | -90 | -86 | -85 | -86 | -87 | -88 | -89 |
| Izinga Lokulanda (Mbps) | 10.7 | 15.3 | 16.7 | 16.7 | 2.54 | 5.77 | 1.22 | 11.1 | 11.0 | 4.68 | 5.07 | 6.98 | 11.4 | 1.89 |
3,Ukuphazamiseka Kwesiginali
Ngo-Ephreli 13,19:33, isignali yaphazanyiswa kungazelelwe.Uma isignali iphazamiseka, isikebhe sokudoba sisogwini kude nesiteshi esingaba ngu-63km (ngaphansi kokuhlolwa).Uma isignali iphazamiseka, amandla esignali ye-CPE ngu-90dbm.Ulwazi lwe-GPS lwesiteshi esiyisisekelo: 120.23388888, 34.286944.I-Flast FTP ulwazi lwephoyinti elivamile le-GPS: 120.9143155, 34.2194236
4,Ukuqedwa kokuhlolwa.
Ngo-15thNgo-Ephreli, zonke izinto amalungu emkhunjini zibuyela ogwini futhi ziqedele ukuhlolwa.
Ukuhlaziywa Kwemiphumela Yokuhlolwa
1,I-engeli yokumboza evundlile ye-antenna kanye nesiqondiso sokuzulazula komkhumbi wokudoba
I-engeli yokumboza ye-antenna ifana kakhulu nomzila womkhumbi.Kusukela kumandla esignali ye-CPE, kungaphethwa ngokuthi i-jitter yesiginali incane kakhulu.Ngale ndlela, i-pan-tilt antenna eqondisayo ingase yanelise kakhulu izidingo zokumbozwa kwesignali olwandle.Ngesikhathi sokuhlolwa, i-antenna eqondisayo ine-engeli enkulu yokusika engu-10 °.
2,Ukuqoshwa kwe-FTP
Igrafu engakwesokudla imelela izinga lokulanda le-FTP lesikhathi sangempela, kanye nolwazi oluhambisanayo lwendawo ye-GPS luboniswa kumephu.Ngesikhathi sokuhlola, kune-jitter yethrafikhi yedatha eminingana futhi amasiginali ezindaweni eziningi mahle.Izinga elimaphakathi lokulanda lingaphezulu kuka-2 Mbps, kanti indawo yokugcina elahlekile yokuxhumana (63km kude nosebe) ingu-1.4 Mbps.
3,Imiphumela yokuhlolwa kwetheminali yeselula
Uxhumano olusuka ku-CPE oluya kunethiwekhi yangasese engenantambo lulahlekile, futhi ividiyo eku-inthanethi ebukwa isisebenzi ibushelelezi kakhulu futhi ayinakho ukunensa.
4,Ukuphazamiseka Kwesiginali
Ngokusekelwe esiteshini esiyisisekelo nezilungiselelo zepharamitha ye-CPE, amandla esignali ye-CPE kufanele abe cishe - 110dbm lapho isignali iphazamiseka.Kodwa-ke, emiphumeleni yokuhlolwa, amandla esignali ngu-90dbm.
Ngemva kokuhlaziywa kwamaqembu, yisizathu esiyinhloko sokunquma ukuthi inani le-NCS alisethelwe ekucushweni kwepharamitha ekude kakhulu.Ngaphambi kokuqala kokuhlolwa, isisebenzi asisethi inani le-NCS endaweni ekude kakhulu ngenxa yokuthi ukulungiselelwa okude kakhulu kuzothinta izinga lokulanda.
Bheka umfanekiso olandelayo:
| Ukucushwa kwe-NCS | Ibhendi yefrikhwensi yethiyori yothi olulodwa (20Mhz Base Station) | Umkhawulokudonsa wethiyori wezimpondo ezimbili (20Mhz Base Station) |
| Setha kulokhu kuhlola | 52Mbps | 110Mbps |
| Ukusethwa okude kakhulu | 25Mbps | 50Mbps |
Isiphakamiso: I-NCS isethelwe kusilungiselelo esikude kakhulu ekuhlolweni okulandelayo, futhi ukuphuma kwesistimu nenani labasebenzisi abaxhunyiwe kuyathinteka lapho i-NCS isethelwe ekucushweni okuhlukile.
Isiphetho
Idatha yokuhlola ebalulekile nolwazi kutholwe ithimba lezobuchwepheshe le-IWAVE ngalokhu kuhlola.Uhlolo luqinisekisa amandla okumbozwa kwenethiwekhi yesistimu yenethiwekhi yangasese engenantambo ye-TD-LTE endaweni yasolwandle kanye nekhono lokumboza isignali olwandle.Khonamanjalo, ngemva kokuba itheminali yeselula ifinyelele ku-inthanethi, isivinini sokulanda se-CPE yamandla aphezulu ngaphansi kwamabanga ahlukene okuzulazula nolwazi lomsebenzisi luyatholwa.
