Tignoolajiyada asalka ah
Isku xirka hadda ayaa aad iyo aad muhiim ugu ah codsiyada badda.Ku haysashada isku xirka iyo isgaarsiinta ee badda waxay u oggolaaneysaa maraakiibta inay si badbaado leh u safraan oo ay u safraan caqabad weyn.
Xalka Shabakadda Gaarka ah ee IWAVE 4G LTEwaxaa laga yaabaa inay xalliso dhibaatadan iyadoo la siinayo shabakad xasilloon, xawaare sare leh, iyo shabakad ammaan ah markabka.
Aynu barano sida nidaamku u caawiyo hoos.

Dejinta Nidaamka Imtixaanka Dhamaystiran
1,Rakibaadda Saldhigga
The Shabakadda gaarka ah ee LTE dhammaan waxay ku taal hal saldhig waxaa la dul dhigay buufin helium ah oo 4 km u jira xeebta.Dhererka ugu badan ee buufinta helium waxay ahayd 500 mitir.Laakiin tijaabadan, dhererkiisa dhabta ah waa ilaa 150m.
Ku rakibida anteenada jihada ee buufinta ayaa lagu muujiyay Fig.2.
Xagasha toosan ee laf-dhabarta weyn waxay ku wajahan tahay oogada badda.Pan-Tilt waxay si dhakhso ah u hagaajin kartaa xagasha toosan ee anteenada si loo hubiyo jihada daboolida calaamadaha iyo aagga.
2,Isku xidhka Shabakadda
Saldhigyada saldhigyada LTE-ga oo dhan-in-one wireless (Patron - A10) ee buufinnada waxay ku xiran yihiin shabakad fiber optic ah iyada oo loo marayo fiilooyinka Ethernet, fiilooyinka fiber optic, transceivers fiber optic, iyo router A. Dhanka kale, waxay ku xiran tahay server-ka FTP (laptop) iyada oo loo marayo router wireless B.
3. Hawlgelinta10watts CPE (Knight-V10)saaran
CPE (Knight-V10) ayaa lagu rakibay dooni kalluumaysi, anteenaduna waxay ku dul-saaran tahay taabsiga dusheeda.Anteenada aasaasiga ah waxay ku rakiban tahay meel 4.5 mitir u jirta heerka badda, anteenada labaadna waxay u jirtaa 3.5 mitir heerka badda.Masaafada u dhaxaysa labada anteeno waa ilaa 1.8 mitir.
Laptop-ka markabku waxa uu la xidhiidhaa CPE-da iyada oo loo sii marayo fiilada shabakadda waxana uu la xidhiidha server-ka fog ee FTP iyada oo loo marayo CPE.Software-ka FPT ee laptop-ka iyo server-ka fog ee FTP ayaa si wadajir ah loo isticmaalaa tijaabinta soo dejinta FTP.Dhanka kale, qalabka tirakoobka taraafikada ee ku shaqeeya laptop-ka wuxuu diiwaangelin karaa taraafikada internetka iyo taraafikada waqtiga dhabta ah.Tijaabiyayaasha kale waxay isticmaalaan taleefoonnada gacanta ama suufka si ay ugu xirmaan WLAN-ka ay dabooleyso CPE-da si ay ugu dhex maraan intarneedka qolka dhexdiisa, sida daawashada filim online ah ama wicitaan fiidiyow ah si ay u tijaabiyaan xawaaraha internetka.

Habka tijaabada
Bilawga Tijaabada
Bishii Abriil 13,15: 33, doon kalluumaysi ayaa shiraacday, 17: 26 isla maalintaas, buufinta waxaa kor loo qaaday ilaa 150 mitir oo heehaabaya.Kadibna, CPE-da waxa ay si bilaa-wireer ah ugu xidhan tahay saldhiga saldhiga, wakhtigan, doonta kaluumaysiga ayaa ka fog saldhiga 33km.
1,Nuxurka Tijaabi
Laptop-ka markabka saaran waxa uu leeyahay soo dejinta FPT, iyo cabbirka faylka bartilmaameedku waa 30G.Software-ka hore loo rakibay ee BWM waxa uu diiwaangeliyaa taraafikada Internetka ee wakhtiga-dhabta ah oo waxa uu ku diiwaangeliyaa macluumaadka GPS-ka wakhtiga dhabta ah ee moobilka.
Shaqaalaha kale ee ku jira doonta kalluumeysiga waxay internetka ka galaan WIFI, daawada muuqaalada onlaynka ah oo sameeya wicitaan muuqaal ah.Fiidiyowga khadka tooska ah waa siman yahay, codka wicitaanka fiidiyowgana waa cad yahay.Imtixaanka oo dhan wuxuu ahaa 33km - 57.5 km.
2,Tijaabi miiska duubista
Inta lagu jiro tijaabada, qaybaha buuxinta markabka waxay diiwaan geliyeen isku-duwayaasha GPS, xoogga calaamada CPE, celceliska heerka soo dejinta FTP, iyo macluumaadka kale ee waqtiga dhabta ah.Jadwalka diiwaanka xogta waa sida soo socota (qiimaha fogaantu waa masaafada u dhaxaysa markabka iyo xeebta, qiimaha soo dejinta waa heerka soo dejinta ee diiwaanka software BWM).
| Fogaanta (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 |
| Xoogga isha (dbm) | -85 | -83 | -83 | -84 | -85 | -83 | -83 | -90 | -86 | -85 | -86 | -87 | -88 | -89 |
| Soo dejinta heerka (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,Calaamadaha ayaa go'a
Abriil 13,19:33, signalka ayaa si lama filaan ah u go'ay.Marka calaamada la gooyo, doonta kaluumaysigu waxay joogtaa xeebta meel ka durugsan saldhiga saldhiga ilaa 63km (baaritaan baa ku socda).Marka calaamadda la gooyo, xoogga calaamada CPE waa - 90dbm.Saldhigga macluumaadka GPS: 120.23388888, 34.286944.Flast FTP-ga caadiga ah xogta GPS: 120.9143155, 34.2194236
4,Tijaabada dhamaystirka
On 15thAbriil, dhammaan alaabta saaran markabka waxay ku soo noqdaan xeebta oo dhammaystiraan tijaabada.
Falanqaynta Natiijooyinka Imtixaanka
1,Xagasha daboolida toosan ee anteenada iyo jihada markabka kalluumaysiga
Xagasha daboolida anteenadu waxay la mid tahay dariiqa markabka.Laga soo bilaabo xoogga calaamada CPE, waxaa lagu soo gabagabeyn karaa in jitter-ku yar yahay.Sidan, anteenada jihada-jiidka ah ayaa laga yaabaa inay si weyn u qanciso shuruudaha caymiska ee badda.Inta lagu jiro tijaabada, anteenada jihada waxay leedahay xagal goynta ugu badan oo ah 10 °.
2,Duubista FTP
Garaafka saxda ah wuxuu u taagan yahay FTP heerka soo dejinta wakhtiga-dhabta ah, iyo macluumaadka goobta GPS ee u dhigma waxay ka muuqataa khariidada.Inta lagu jiro tijaabinta, waxaa jira dhowr xog oo gariiraya taraafikada iyo calaamadaha gobollada intooda badan waa wanaagsan yihiin.Celceliska heerka soo dajintu wuu ka sarreeyaa 2 Mbps, meesha xidhiidhka lumay ee ugu dambeeyay (63km u jirta xeebta) waa 1.4 Mbps.
3,Natiijooyinka imtixaanka terminalka mobilada
Isku xirka CPE ee shabakada gaarka ah ee wireless ayaa lumay, fiidiyoowga internetka ee uu daawado shaqaaluhu waa mid aad u siman oo aan lahayn dib u dhac.
4,Calaamadaha ayaa go'a
Iyada oo ku saleysan saldhigga saldhigga iyo goobaha cabbirka CPE, xoogga calaamada CPE waa in ay ahaataa qiyaastii -110dbm marka calaamaduhu go'o.Si kastaba ha noqotee, natiijooyinka imtixaanka, xoogga calaamaduhu waa - 90dbm.
Falanqaynta kooxaha ka dib, waa sababta koowaad ee lagu qiyaaso in qiimaha NCS aan lagu dejin qaabaynta cabbirka fog.Kahor bilowga imtixaanka, shaqaaluhu ma dejiyo qiimaha NCS goobta ugu fog sababtoo ah goobta ugu fog waxay saameyn doontaa heerka soo dejinta.
Tixraac jaantuskan soo socda:
| Habaynta NCS | Kooxda soo noqnoqda aragtida ee hal anteeno ( Saldhigga Saldhigga 20Mhz) | bandwidth aragti ee anteenooyinka dual ( Saldhigga Saldhigga 20Mhz) |
| Dejinta Imtixaankan | 52Mbps | 110Mbps |
| Dejinta ugu fog | 25Mbps | 50Mbps |
Soo jeedin: NCS waxaa loo dejiyay goobta ugu fog ee imtixaanka soo socda, iyo soo saarista nidaamka iyo tirada isticmaalayaasha ku xiran ayaa ka walaacsan marka NCS loo dejiyo qaabayn ka duwan.
Gabagabo
Xogta iyo waayo-aragnimada tijaabada ee qiimaha leh waxaa helay kooxda farsamada IWAVE iyada oo loo marayo tijaabadan.Imtixaanku wuxuu xaqiijinayaa awoodda daboolida shabakada ee nidaamka shabakadaha gaarka ah ee TD-LTE ee jawiga badda iyo awooda daboolida ishaarada ee bada.Dhanka kale, ka dib marka terminalka mobaylka uu galo internetka, xawaaraha soo dejinta ee awoodda sare ee CPE ee hoos yimaada masaafadaha kala duwan ee socodka iyo khibradda isticmaalaha ayaa la helaa.
