Musi wa2 Mbudzi 2019, timu yeIWAVE yakakokwa nedhipatimendi remoto muFujian Province, yakatora nhevedzano yekurovedza muviri musango kuyedza 4G-LTE yekukurumidzira yekuraira kutaurirana system kushanda.Iri faira mhedziso pfupi yemaitiro ekuita.

1.Background

Kana vedhipatimendi rezvemoto parinoziviswa kuti masango abvira moto, munhu wose ari mudhipatimendi racho anofanira kupindura nokukurumidza uye zvakasimba.Mujaho uchipesana nenguva nekuti kuchengetedza nguva kuponesa hupenyu.Pakati peaya maminetsi ekutanga akakosha, vanopindura vekutanga vanoda kukurumidza kutumirwa asi yepamberi yekutaurirana sisitimu inobatanidza nese zviwanikwa zvevanhu.Uye iyo sisitimu inoda kumisa pane yakazvimiririra, Broadband uye yakagadzikana isina waya network inobvumira chaiyo nguva izwi, vhidhiyo uye data kutapurirana pasina kutsamira pane chero zviwanikwa zvekutengesa.

 

Pakukoka kweFujian Province Fire department, IWAVE yakaronga nyanzvi dzezvekufambiswa kwemashoko, nyanzvi dzekuchengetedzwa kwemasango, uye mukuru wemasango kuti aite zvakatevedzana zvekudhirowa nekukurumidza kuendesa 4G TD-LTE yakavanzika network mumasango.

Ukobvu hwevhu: 40-100cm

3.Zviri mukati meZviitwa

Themaekisesaizichinangwa chekuongorora:

 

① NLOS kutapurirana kugona musango gobvu

② Kuvharirwa kwetiweki padivi pemoto

③ Mafambisirwo ehurongwa hwekukurukurirana kune zviitiko zvechimbichimbi musango.

3.1.ExerciseyeNLOS kutapurirana mune dense forest

Kuita kuti varwi kana vekutanga vanopindura vabatanidzwe zvisina waya mumasango akaomesesa uye nehutsinye nharaunda nharaunda, zvinopa zvakati wandei zvakanaka mumamiriro ekukurumidzira.

Mukuyedzwa uku tichaita kuti michina yekutaurirana isina waya ishande mumamiriro akanyanya kuratidza kugona kwayo kweNLOS.

Deployment

Isa iyo inotakurika emergency sisitimu (Patron-P10) munzvimbo ine gwenzi rakaoma uye rakakora (longitude: 117.705754, latitude: 24.352767)

Iye Patron-P10

Pakati Frequency: 586Mhz

Bandwidth: 10Mhz

RF Simba: 10watts

Test Result

Vhidhiyo yekufambisa uye kutaurirana kwezwi zvakachengetwa panguva yekufamba kwese kusvika CPE yarasa kubatana nevatsigiri-P10.Sezvinoratidzwa pamufananidzo uri pamusoro (Green color inoreva kuti vhidhiyo uye izwi rakatsetseka).

Trunking Handset

Muyedzi paakafamba pa628metres kubva patron-p10 nzvimbo, chibatiso chakarasika hukama nemutengi-p10.Ipapo iyo handset inobatanidza neCPE kuburikidza neWi-Fi uye iyo chaiyo nguva izwi uye vhidhiyo kutaurirana zvakapora zvakajairika.

Manpack CPE

Muedzi paakafamba nepamusoro pemateru, CPE yakarasa kubatana.Panguva ino simba rechiratidzo raive -98dBm (Apo muongorori akamira pamusoro pemateru, chiyero che data chaive 10Mbps)

3.2.Exercise yeNetiweki kuvharika pamwe nepanopisa moto musango

Firebreak igap muzvinomera rinoita sechivharidzo kunonoka kana kumisa kufambira mberi kwemoto wesango.Uye zvidzitiro zvemoto zvinoshandawo semigwagwa yekufamba kwemakomo nekuchengetedzwa kwemasango, kufungidzira kwesimba rekudzimisa moto, midziyo yekudzima moto, chikafu, uye zvimwe zvinhu zvekutsigira zvekutakura zvinhu, izvo zvinoita basa rakakosha mukupisa masango.

Kuti upindure kune chiitiko chekukurumidzira munzvimbo yemasango, kuvhara moto wemoto netiweki yakagadzikana uye yakakwirira-inomhanya ibasa rakaoma.Munzvimbo yekuyedza inoratidzwa pamufananidzo uri pamusoro, timu yeIWAVE ichashandisa Patron-P10 yekuvhara moto ine 4G-LTE yakavanzika network yekutaurirana kwakagadzikana.

Deployment

Kurumidza kuendesa inotakurika yakasanganiswa base station (Patron-P10), kutumirwa kwese kwakatora 15minutes.

Test Mhedzisiro

Iyo tester ine handset uye CPE yakachengeta chaiyo nguva vhidhiyo uye kutaurirana kwezwi nevanhu panzvimbo inotakurika yakabatanidzwa base station station (Ita sekuraira kwekukurumidzira uye nzvimbo yekutumira).

Sezvinoratidzwa mumufananidzo uri pasi apa, nzira yakasvibirira yekufamba inoreva kuti vhidhiyo uye izwi rakatsetseka uye rakajeka.

Muedzi paakafamba achitevedza zhenje remoto ndokufamba nepamusoro pechikomo, kutaurirana kwakarasika.Nekuti chikomo chakakwirira 200metres kupfuura base chiteshi nzvimbo, saka masaini akavharika uye akarasa kubatana.

Muedzi paakafamba achidzika nemoto, chinongedzo chakarasika pakupera kwemoto.Iyo nzvimbo yakadzikira 90metres pane base base station deployment place.

Muzvibooreso zviviri izvi, hatina kuisa antenna yekukurumidzira yekutaurirana munzvimbo yepamusoro semuenzaniso isa antenna pamusoro pemotokari yekukurumidzira.Panguva yekudzidzira chaiko, kana tikaisa antenna kumusoro, chinhambwe chinenge chakareba.
