10.Can it kugovera nguva yakawanda slots kuti vhidhiyo kutapurirana?

The physical layer's TS (time slot, senge pilot time slot, uplink, and downlink service time slot, synchronization time slot, etc.) algorithm allocation is preset uye haigone kugadziridzwa zvine simba nemushandisi.

11.Can it kugovera nguva yakawanda slots kuti vhidhiyo kutapurirana?

Iyo yemuviri layer algorithm yakamisikidzwa kune iyo TS (nguva slot) yekugovera algorithm uye haigone kugadziridzwa zvine simba nemushandisi. Uye zvakare, iyo inoenderana kugadzirisa pazasi peiyo yemuviri layer (TS kugoverwa ndeyeyepasi pasi peiyo yemuviri layer) haina basa kana iyo data iri vhidhiyo kana izwi kana data rakawanda, saka haizogoveri TS yakawanda nekuda kwekuti ndiko kutapurirana kwevhidhiyo.

.

Nguva yekubatanidza ndeye 30ms.

Chiyero chekutumira data chinotsamira kwete chete pachinhambwe chekufambisa, asiwo pane zvakasiyana-siyana zvisina waya zvezvakatipoteredza, seSNR.Per ruzivo rwedu, The 200mw MESH module FD-6100 kana FD-61MN, mhepo kusvika pasi 11km, 7-8Mbps The 200mw nyeredzi topology module FDM-6600 kana FDM-66MN: Mhepo kusvika pasi 22km: 1.5-2Mbps

14.Ndeipi simba rinogadziriswa reFD-6100 uye FDM-6600?

-40dbm~+25dBm

15.How kudzorera fekitari Settings of FD-6100 uye FDM-6600?

Mushure mekutanga, dhonza GPIO4 pasi, dzima uye tangazve FD-6100 kana FDM-6600. Mushure mekunge GPIO4 ikaramba ichidhonzwa pasi kwemasekonzi gumi, wozoburitsa GPIO4. Panguva ino, mushure mekutambisa, ichadzorerwa kufekitari. Uye iyo default IP ndeye 192.168.1.12

16.Ndeipi max inofamba kumhanya iyo FDM-6680, FDM-6600 uye FD-6100 inogona kutsigira?

FDM-6680: 300km/h FDM-6600: 200km/h FD-6100: 80km/h

Ivo vanotsigira 1T2R. Pakati peaviri maRF interfaces, imwe ndeye AUX. interface, iyo inogona kushandiswa pakugamuchira kusiyana-siyana kuvandudza isina waya yekugamuchira. kunzwa (kune 2dbi ~ 3dbi mutsauko pakati peyakabatana uye isina kubatana antenna neAUX port).

18.Ko FDM-6680 inotsigira MIMO here?

Ehe. Inotsigira 2X2 MIMO.

19.Ndeipi iyo yakanyanya relay kugona? Iyo data rate inoshanduka sei zvichienderana nerelay kuverenga.

Kurudziro yedu inodarika gumi neshanu relay, asi iyo chaiyo relay huwandu hunofanirwa kunge hwakavakirwa pane chaiyo networking nharaunda panguva yekushandisa. Mune dzidziso, imwe neimwe yekuwedzera relay inodzikisa iyo data kuburikidza ne1/3 (asi zvakare pasi pechiratidzo chemhando uye kukanganiswa kwezvakatipoteredza uye zvimwe zvinhu).

. Ndeipi iyo shoma SNR kukosha mune iyi kesi?

Ngatitorei muenzaniso kutsanangura mubvunzo uyu: Kana UAV ikabhururuka kureba kwemamita 100 ine FD-6100 kana FD-61MN module pabhodhi (max daro reFD-6100 neFD-61MN ingangoita 11km), antenna yekugamuchira unit inogadziriswa 1.5 metres pamusoro pevhu.

Kana iwe ukashandisa 2dbi antenna kune ese ari maviri. Tx neRx Kana chinhambwe kubva kuUAV kuenda kunzvimbo yekudzora pasi iri 11km, iyo SNR inenge +2, uye chiyero chekutumira data i2Mbps.

Kana ukashandisa 2dbi Tx antenna, 5dbi Rx antenna. Kana chinhambwe kubva kuUAV kuenda kunzvimbo yekudzora pasi chiri 11km, iyo SNR inenge +6 kana +7, uye chiyero chekutumira data i7-8Mbps.

21Inoita frequency hopping here?

FHHS frequency hopping inotemerwa neyakavakirwa-mukati algorithm. Iyo algorithm ichasarudza yakaringana frequency point zvichienderana neazvino kupindira mamiriro uye wobva waita iyo FHSS kusvetukira kune iyo yakakwana frequency point.
