Pa 2nd Nov 2019, gulu la IWAVE litayitanidwa ndi dipatimenti yozimitsa moto m'chigawo cha Fujian, adachita masewera olimbitsa thupi m'nkhalango kuti ayese momwe 4G-LTE imagwirira ntchito mwadzidzidzi.Fayiloyi ndi yomaliza mwachidule pazochita zolimbitsa thupi.
1.Mbiri
Oyang'anira ozimitsa moto akazindikira kuti nkhalango yabuka, aliyense m'dipatimentiyi akufunika kuchitapo kanthu mofulumira komanso motsimikiza.Ndi mpikisano wotsutsana ndi nthawi chifukwa kusunga nthawi ndikupulumutsa miyoyo.Pamphindi zovuta zoyambazo, oyankha oyamba amafunikira njira yolumikizirana yofulumira koma yotsogola yomwe imalumikizana ndi anthu onse.Ndipo dongosololi liyenera kukhazikika pa intaneti yodziyimira payokha, yotakata komanso yosasunthika yopanda zingwe yomwe imalola kuti nthawi yeniyeni ya mawu, makanema ndi kutumiza ma data popanda kudalira pazinthu zilizonse zamalonda.
Poyitanidwa ndi dipatimenti yozimitsa moto m'chigawo cha Fujian, IWAVE inakonza akatswiri olankhulana, akatswiri oteteza nkhalango, komanso woyang'anira nkhalango wamkulu kuti achite zoyeserera za kutumiza mwachangu maukonde achinsinsi a 4G TD-LTE m'nkhalango.
2.Zogwirizana ndi Geographical
Malo: Jiulongling Forest Farm, Longhai, Zhangzhou, Fujian, China
Malo: Malo amapiri a m'mphepete mwa nyanja
Kutalika: 25-540.7mita
Kutsika: 20-30 digiri
Kukula kwa dothi: 40-100cm
3.Zamkatimu Zolimbitsa Thupi
Themasewera olimbitsa thupicholinga kutsimikizira:
① Kutha kufalitsa kwa NLOS m'nkhalango zowirira
② Kufalikira kwa netiweki pamoto woyaka moto
③ Kachitidwe ka njira yolumikizirana pazochitika zadzidzidzi m'nkhalango.
3.1.Masewera olimbitsa thupikwa kufalitsa kwa NLOS mu wandiweyani forest
Kupanga asitikali kapena oyankha oyamba kulumikizidwa opanda zingwe m'nkhalango zowirira komanso malo owopsa achilengedwe, zidzapereka zabwino zingapo pakagwa mwadzidzidzi.
Pakuyesa uku tipanga zida zoyankhulirana zopanda zingwe kuti zizigwira ntchito movutikira kuti zitsimikizire luso lake la NLOS.
Kutumiza
Tumizani makina onyamulika azadzidzidzi (Patron-P10) pamalo okhala ndi chitsamba cholimba komanso chowundana (longitudo: 117.705754, latitude: 24.352767)
Pakati pafupipafupi: 586Mhz
Bandwidth: 10Mhz
RF Mphamvu: 10watts
Kachiwiri, anthu oyesa anatenga manpack CPE ndi trunking handset akuyenda momasuka m'nkhalango.Pakuyenda, kuyankhulana kwavidiyo ndi mawu kumafunika kupitiriza.
Zotsatira za mayeso
Kutumiza kwamavidiyo ndi kuyankhulana kwamawu kudapitilizidwa pakuyenda konse mpaka CPE idataya kulumikizana ndi woyang'anira-P10.Monga momwe tawonetsera pa chithunzi pamwambapa (mtundu wobiriwira umatanthauza kuti kanema ndi mawu ndi osalala).
Trunking Handset
Woyesa atayenda pa 628meters kutali ndi malo a patron-p10, foni yam'manja idataya kulumikizana ndi woyang'anira-p10.Kenako foni yam'manja imalumikizana ndi CPE kudzera pa Wi-Fi ndipo kulumikizana kwa mawu ndi makanema nthawi yeniyeni kunachira.
Manpack CPE
Woyesa atadutsa potsetsereka kwambiri, CPE idataya kulumikizana.Panthawiyi mphamvu ya chizindikiro inali -98dBm (Pamene woyesayo adayima pamwamba pa malo otsetsereka, chiwerengero cha deta chinali 10Mbps)
3.2.Masewera olimbitsa thupi kwa Network Kuphimba m'mbali mwa firebreak m'nkhalango
Firebreak ndi kusiyana kwa zomera komwe kumakhala ngati chotchinga kuti chichepetse kapena kuyimitsa moto wa m'nkhalango.Ndipo zozimitsa motozi zimagwiranso ntchito ngati misewu yoyang'anira mapiri ndi kuteteza nkhalango, kuwonetsa mphamvu zozimitsa moto, zida zozimitsa moto, chakudya, ndi zinthu zina zothandizira popereka zinthu, zomwe zimagwira ntchito yofunika kwambiri pakuzimitsa moto m'nkhalango.
Poyankha zochitika zadzidzidzi m'dera la nkhalango, kuphimba chowotcha moto ndi intaneti yokhazikika komanso yothamanga kwambiri ndi ntchito yovuta.M'malo oyesera omwe akuwonetsedwa pachithunzi pamwambapa, gulu la IWAVE lidzagwiritsa ntchito Patron-P10 kuphimba moto ndi netiweki yachinsinsi ya 4G-LTE pakulankhulana kokhazikika.
Kutumiza
Tumizani mwachangu malo ophatikizika osunthika (Patron-P10), kutumizidwa konseko kudatenga 15minutes.
Pakati pafupipafupi: 586Mhz
Bandwidth: 10Mhz
RF Mphamvu: 10watts
Kenako woyesayo adatenga CPE ndipo cholumikizira cham'manja chidayenda pamoto
Yesani Zotsatira
Woyesa wokhala ndi foni yam'manja ndi CPE amasunga nthawi yeniyeni yolumikizirana ndi makanema ndi mawu ndi anthu omwe ali pamalo ophatikizika a station station (Chitani ngati lamulo ladzidzidzi ndi malo otumizira).
Monga momwe tawonetsera pachithunzichi, njira yobiriwira yobiriwira imatanthauza kuti kanema ndi mawu ndi osalala komanso omveka bwino.
Pamene woyesayo anayenda m'mbali mwa choyatsira moto ndikuyenda pamwamba pa phiri, kulankhulana kunatayika.Chifukwa phirilo ndi lalitali 200meters kuposa malo oyambira, ndiye kuti ma siginecha adatsekedwa ndikutaya kulumikizana.
Pamene woyesa anayenda pansi pa choyatsira moto, cholumikizira chinatayika kumapeto kwa choyatsira moto.Malowa ndi otsika ndi 90meters kuposa malo oyambira station station.
M'mabowo awiriwa, sitinayike mlongoti wa njira yolumikizirana mwadzidzidzi pamalo apamwamba mwachitsanzo kuyika mlongoti pamwamba pagalimoto yolumikizirana mwadzidzidzi.Pakuchita zenizeni, ngati tiyika mlongoti pamwamba, mtunda udzakhala wautali.
