4000 mitir ee Tibet Plateaucalaamada tunnelwaa miskiin! Xidhiidhka shaqaalaha tunnelku waa mid aan haboonayn, taas oo saamaynaysa horumarka dhismaha. Maxaan samayn karnaa? La wanaajiyey cDhammaan + calaamadaha Internetka, Kor-u-qaadista Digniinta Lintratek waxay adeegsatay laba kor-u-qaadeyaasha calaamadaha fiber-ka indhaha si ay u xalliyaan dhibaatada calaamadda daciifka ah ee tunnel-ka.Saameyntu aad ayey uga badan tahay sidii la filayey, shaqaaluhuna si joogta ah ayey u ammaanaan.
Faahfaahinta Mashruuca
| Daboolista calaamadaha tunnel-ka Plateau | |
| Goobta Mashruuca | Magaalada Qamdo, Gobolka Xizang, Shiinaha |
| Fogaanta Daboosha | 1km |
| Nooca Mashruuca | Ganacsi |
| Muuqaalka mashruuca | Macmiilku wuxuu ku yaalaa meel 4000 mitir ah oo dhulka ah, meesha u dhow ee dadku ku yar yahay, calaamada telefoonka gacanta oo liita, shaqaalaha dhismahan ayaa ah mid aad u dhib badan. |
| Shuruudaha Macmiilka | Kobcinta shabakadaha 2G-4G ee labada hawlwadeen ee waaweyn |
Macmiilku waxa uu ka dhisayaa tunnel-ka Tibetan Plateau, shaqaalaha dhismuhuna ma samayn karaan oo ma heli karaan wicitaanno caadi ah sababtoo ah tirada dadka iyo taleefoonnada gacanta oo liita ee u dhow tunnelka. Waxa uu rajeynayaa in uu sameeyo daboolka kor u qaadista calaamadaha ee labada tunnel ee waaweyn, oo daboolaya signalka taleefanka gacanta ee masaafo kiiloomitir u jira tunnelka, iyo kor u qaadida shabakada 2G-4G ee labada hawlwadeen ee waaweyn.
Qorshaha Naqshadeynta
Ka dib markii lala xiriiro macaamilka, Injineerka Lintratek wuxuu xaqiijiyay in qalabku uu qaato laba qaybood oo ah 5W dual-frequency GD analog.xoojiye signal fiber indhaha, siday u kala horreeyaan rakibidda dhamaadka dhow eekor u qaadayaasha fibbarka indhahalabada godadka, rakibidda remoteer fog oo ku saabsan 500 mitir ka fog godka, iyo rakibidda laba anteeno saxan weyn ka repeater fog iyada oo loo marayo xidhiidhada feeder, mid ka mid ah weheliyaan bidix iyo midig ee godka transverse, iyo gudbinta calaamadaha labada dhinac godka daloosha.
Isticmaalayaasha Android waxay soo dejisan karaan "CellularZ" si ay u ogaadaan qiyamka calaamadaha, "BAND" waxaa loola jeedaa xargaha soo noqnoqda signalka taleefanka gacanta, oo ku lug leh aqoonta isgaarsiinta, waxaad la tashan kartaa xirfadlayaal; "RSRP" waa qiimaha caadiga ah ee lagu cabbiro in calaamaduhu siman yihiin, halbeegga calaamaduhu waa dBm, cabbirku waa -50dBm ilaa -130dBm, yaraanta qiimaha saxda ah, ayaa sii xoogaysanaya calaamadda. Xogta tijaabada hore loo sii rakibay waxay muujisay inaysan jirin wax calaamad ah oo loogu talagalay mobilada iyo isgaarsiinta labadaba. Iphones-ka, waxaad nala soo xiriiri kartaa si aad u weydiiso sida loo tijaabiyo.
Ka dib markii la ogaado calaamadda, waxay caddaysay inaysan jirin wax calaamad maxalli ah.
Qorshaha Alaabta
Noocan ah4g ltd network fidiyahawaa chassis injineernimo awood sare leh wuxuuna taageeraa habeynta xadhkaha soo noqnoqda ee soo socda. Sida laga soo xigtay ogaanshaha signalka (waxay u baahan tahay ogaanshaha caawimo xirfadle ah), aagga caymiska CDMA, GSM, DSC signal band waa mid xoogan, saddexdan kooxood waxay taageeraan baahida macaamiisha ee labada hawlwadeen ee waaweyn ee 2G-4G, wicitaanada internetka waa siman yihiin.
Rakibaadda Goobta
1. Ku celiyaha signalka fog iyo rakibida soo celinta signalka dhamaadka u dhaw:
Lagu rakibay dhamaadka dhow ee soo noqnoqda fiber indhaha ee godka, oo ku rakib dhamaadka fog ee soo noqnoqda fiilada indhaha oo ku dhawaad 500 mitir u jirta godka.
2. Rakibaadda anteenada gudbinta:
Laba anteenooyin waaweyn oo saxan ah ayaa lagu rakibay mishiinka fog iyadoo loo marayo isku xirka feederiyeyaasha, mid ka mid ah dhinacyada bidix iyo midig ee godka transverse, iyo calaamadaha waxaa lagu kala qaadaa labada dhinac ee godka transverse.
3. Bilow sahayda korontada ka dib markii anteenooyinka soo dhaweynta iyo gudbinta ay ku xiran yihiin martigeliyaha; haddii kale, qofka martida loo yahay wuu dhaawacmi doonaa.
4. Ogaanshaha ishaarada
Ka dib markii la rakibo, waxaad si toos ah u ogaan kartaa signalka online, ama waxaad isticmaali kartaa software "CellularZ" si aad u ogaato saameynta.
Macaamiilku wuxuu u maleeyay in mitirka 4000 ee dhulka aan la degganeyn, ugu badnaan kor u qaadida shabakadda wacitaanka 2G, laakiin ka dib hagidda rakibidda kooxda Lin Chuang, hadda wicitaanku dhib ma laha, internetka sidoo kale waa mid aad u fudud, aad baad ugu mahadsan tahay hagida bukaanka ee injineerka, laga bilaabo amarka ilaa xalku waa mid aad u dhakhso badan.
