Cwangcisa inkqubo yoVavanyo oluGqibeleleyo
1,Ukufakela iSikhululo esiSiseko
I Inethiwekhi yabucala ye-LTE yonke kwisikhululo esisisiseko esinye ibekwe kwibhaluni ye-helium ekumgama oziikhilomitha ezi-4 ukusuka elunxwemeni.Ukuphakama kwebhaluni ye-helium yayiziimitha ezingama-500.Kodwa kolu vavanyo, ubude bayo bokwenene bumalunga ne-150m.
Ukufakwa kwe-antenna yolwalathiso kwibhaluni kuboniswe kwi-FIG.2.
I-engile ethe tyaba ye-lobe ephambili ijongene nomphezulu wolwandle.I-Pan-Tilt inokuhlengahlengisa ngokukhawuleza i-engile ethe tyaba ye-eriyali ukuqinisekisa isalathiso somqondiso kunye nendawo.
2,Uqwalaselo lweNethiwekhi
Izikhululo zesiseko ze-LTE ezingenazintambo zonke-kwinye (i-Patron - A10) kwiibhaluni zixhunyiwe kwinethiwekhi ye-fiber optic nge-Ethernet cables, i-fiber optic cables, i-fiber optic transceivers, kunye ne-router A. Okwangoku, ixhunyiwe kwi-server ye-FTP (laptop ) ngokusebenzisa irutha engenazingcingo B.
3, Ukusasazwa10watts CPE (Knight-V10)ukhwelile
I-CPE (i-Knight-V10) ifakwe kwisikhephe sokuloba kwaye i-eriyali ifakwe phezu kwekhebhu.I-eriyali yokuqala ifakwe kwi-4.5 yeemitha ukusuka kwinqanaba lolwandle kwaye i-eriyali yesibini i-3.5 yeemitha ukusuka kwinqanaba lolwandle.Umgama phakathi kwee-eriyali ezimbini malunga neemitha ezi-1.8.
Ilaptop esenqanaweni inxulumene neCPE ngentambo yenethiwekhi kwaye inxulumene neseva yeFTP ekude ngeCPE.Isoftware yeFPT yelaptop kunye neseva yeFTP ekude zisetyenziswa kunye kuvavanyo lokhuphelo lweFTP.Ngeli xesha, isixhobo sezibalo zetrafikhi esisebenza kwilaptop sinokurekhoda itrafikhi ye-Intanethi kunye nokugcwala ngexesha lokwenyani.Abanye abavavanyi basebenzisa iiselfowuni eziphathwayo okanye iipads ukudibanisa kwi-WLAN egqunywe yi-CPE ukusefa i-Intanethi ekhabhathini, njengokubukela imuvi ekwi-intanethi okanye ukufowuna ngevidiyo ukuvavanya isantya se-Intanethi.
Ulungelelwaniso lweSikhululo esiSiseko
| Ubuninzi bombindi: 575Mhz |
| Ububanzi: 10Mhz |
| Amandla angenazingcingo: 2 * 39.8 dbm |
| Umlinganiselo okhethekileyo we-subframe: 2:5 |
| NC: iqwalaselwe njengo-8 |
| I-antenna SWR: i-eriyali engundoqo 1.17, i-eriyali encedisayo 1.20 |
Inkqubo yovavanyo
Ukuqala kovavanyo
Ngo-Epreli 13, 15:33, isikhephe sokuloba sasihamba, kwaye ngo-17: 26 kwangolo suku lunye, ibhaluni yanyuswa yaya kumphakamo we-150meters kwaye yandanda.Emva koko, i-CPE ixhunywe ngaphandle kwamacingo kwisikhululo sesiseko, kwaye ngeli xesha, isikhephe sokuloba sikude nesikhululo se-33km.
1,Isiqulatho soVavanyo
Ilaptop kwinqanawa inokhuphelo lweFPT, kwaye ubungakanani befayile ekujoliswe kuyo yi30G.Isoftware ye-BWM efakwe ngaphambili irekhoda ixesha lokwenyani lokugcwala kwi-Intanethi kwaye irekhoda ulwazi lweGPS ngexesha lokwenyani ngefowuni ephathwayo.
Abanye abasebenzi kwisikhephe sokuloba bafikelela kwi-Intanethi nge-WIFI, babukele iividiyo ze-intanethi kwaye benze umnxeba wevidiyo.Ividiyo ekwi-Intanethi igudileyo, kwaye ilizwi lokufowuna ngevidiyo licacile.Uvavanyo lonke lwaluyi-33km - 57.5 km.
2,Itheyibhile yokurekhoda yovavanyo
Ngexesha lovavanyo, amacandelo okugcwalisa kwinqanawa irekhodi yeGPS ilungelelanisa, amandla ophawu lweCPE, umyinge wokukhuphela we-FTP, kunye nolunye ulwazi ngexesha lokwenyani.Itheyibhile yerekhodi yedatha ilandelayo (ixabiso lomgama ngumgama phakathi kwenqanawa kunye nonxweme, ixabiso lokukhuphela izinga lokukhuphela irekhodi ye-software ye-BWM).
| Umgama (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 oMqondiso (dbm) | -85 | -83 | -83 | -84 | -85 | -83 | -83 | -90 | -86 | -85 | -86 | -87 | -88 | -89 |
| Ireyithi yokuthoba umthwalo (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 koMqondiso
Ngo-Epreli 13, 19: 33, umqondiso waphazamiseka ngequbuliso.Xa umqondiso uphazamiseka, isikhephe sokuloba siselunxwemeni kude nesikhululo esisezantsi malunga ne-63km (phantsi kokuhlolwa).Xa umqondiso uphazamiseka, amandla omqondiso we-CPE ngu-90dbm.Ulwazi lwe-GPS lwesikhululo sesiseko: 120.23388888, 34.286944.I-FTP yeFTP eqhelekileyo iphoyinti yolwazi lweGPS: 120.9143155, 34.2194236
4,Ukugqitywa kovavanyo.
Ngo15thEpreli, onke amalungu enqanawa abuyela elunxwemeni kwaye agqibezele uvavanyo.
Uhlalutyo lweziphumo zovavanyo
1,I-engile yokugubungela ethe tyaba ye-eriyali kunye nesikhokelo sokuhamba ngenqanawa yokuloba
I-angle yokugubungela i-eriyali iyafana kakhulu nendlela yenqanawa.Ukususela kumandla omqondiso we-CPE, kunokugqitywa ukuba i-jitter yesignali incinci.Ngale ndlela, i-eriyali ye-pan-tilt inokwanelisa kakhulu iimfuno zokugubungela umqondiso elwandle.Ngexesha lokuvavanya, i-antenna ye-directional ine-angle ephezulu yokunqunyulwa kwe-10 °.
2,FTP Recording
Igrafu echanekileyo imele i-FTP yexesha langempela lokukhuphela izinga, kunye nolwazi oluhambelana nendawo ye-GPS lubonakaliswe kwimephu.Ngexesha lovavanyo, zininzi i-jitter yedatha yedatha kwaye imiqondiso kwimimandla emininzi ilungile.Izinga lokukhuphela eliphakathi liphezulu kune-2 Mbps, kwaye indawo yokugqibela elahlekileyo yoxhumo (i-63km kude nonxweme) yi-1.4 Mbps.
3,Iziphumo zovavanyo lwetheminali yeselula
Uqhagamshelo olusuka kwi-CPE ukuya kuthungelwano lwabucala olungenazingcingo lulahlekile, kwaye ividiyo ekwi-intanethi ejongwe ngumsebenzi igudile kakhulu kwaye ayinayo i-lag.
4,Ukuphazamiseka koMqondiso
Ngokusekelwe kwisikhululo sesiseko kunye nezicwangciso zeparamitha yeCPE, amandla omqondiso weCPE kufuneka abe malunga ne-110dbm xa umqondiso uphazamiseka.Nangona kunjalo, kwiziphumo zovavanyo, amandla omqondiso ngu-90dbm.
Emva kokuhlalutya kwamaqela, sesona sizathu siphambili sokuchaza ukuba ixabiso le-NCS alimiselwanga kuqwalaselo olude kakhulu lweparameter.Ngaphambi kokuqala kovavanyo, umsebenzi akawubeki ixabiso le-NCS kwindawo ekude kakhulu kuba indawo ekude kakhulu iya kuchaphazela izinga lokukhuphela.
Jonga kulo mfanekiso ulandelayo:
| Uqwalaselo lwe-NCS | Ibhendi yethiyori yefrikhwensi ye-eriyali enye (20Mhz Isikhululo esisisiseko) | I-bandwidth yethiyori yee-eriyali ezimbini (20Mhz Isikhululo esisisiseko) |
| Seta kolu Vavanyo | 52Mbps | 110Mbps |
| Eyona Setup ikude | 25Mbps | 50Mbps |
Ingcebiso: I-NCS isetelwe kweyona ndlela ikude kuvavanyo olulandelayo, kwaye i-throughput yesistim kunye nenani labasebenzisi abaqhagamshelweyo bayachaphazeleka xa i-NCS isetelwe kuqwalaselo olwahlukileyo.
Ukuqukumbela
Idatha yovavanyo oluxabisekileyo kunye namava afunyenwe liqela lobugcisa be-IWAVE ngolu vavanyo.Uvavanyo luqinisekisa isakhono sothungelwano lwe-TD-LTE yenethiwekhi yabucala engenangcingo kwimo engqongileyo yaselwandle kunye nokukwazi ukugubungela umqondiso elwandle.Okwangoku, emva kokuba i-terminal yeselula ifikelele kwi-Intanethi, isantya sokukhuphela i-CPE yamandla aphezulu phantsi komgama ohlukeneyo wokuhamba kunye namava omsebenzisi afunyenwe.
