Baxhasa i-1T2R. Phakathi kojongano lweRF ezimbini, enye yi-AUX. ujongano, olungasetyenziselwa ukwahluka kolwamkelo ukuphucula ulwamkelo olungenazingcingo. uvakalelo (kukho i-2dbi ~ 3dbi umahluko phakathi kwe-eriyali eqhagamshelweyo nengaqhagamshelwanga nge-AUX port).

18.Ngaba i-FDM-6680 iyayixhasa i-MIMO?

Ewe. Ixhasa i-2X2 MIMO.

19.Yintoni eyona nto iphezulu yesakhono sokudlulisa? Ingaba ireyiti yedatha itshintsha njani ngokokubalwa kodluliselo.

Isindululo sethu siphezulu se-15 relay, kodwa ubuninzi be-relay bokwenene kufuneka busekelwe kwindawo yothungelwano lwangempela ngexesha lokufaka isicelo. Kwithiyori, i-relay nganye eyongezelelweyo iya kunciphisa i-throughput yedatha malunga ne-1/3 (kodwa ixhomekeke kumgangatho wesignali kunye nokuphazamiseka kokusingqongileyo kunye nezinye izinto).

20.Ngowuphi umlinganiselo wedatha omkhulu onokuthi udluliselwe kuluhlu oluphezulu oluchaziweyo? Leliphi ixabiso eliphantsi le-SNR kule meko?

Makhe sithathe umzekelo ukuze sicacise lo mbuzo: Ukuba i-UAV ibhabha kumphakamo weemitha ezili-100 kunye nemodyuli ye-FD-6100 okanye i-FD-61MN ebhodini (ubukhulu bomgama we-FD-6100 kunye ne-FD-61MN malunga ne-11km), i-eriyali iyunithi yomamkeli uzinzile 1.5 yeemitha ngaphezu komhlaba.

Ukuba usebenzisa i-eriyali ye-2dbi kuzo zombini. I-Tx kunye ne-Rx Xa umgama ukusuka kwi-UAV ukuya kwiziko lokulawula umhlaba liyi-11km, i-SNR i malunga + ne-2, kwaye izinga lokudluliselwa kwedatha yi-2Mbps.

Ukuba usebenzisa i-eriyali ye-2dbi Tx, i-eriyali eyi-5dbi Rx. Xa umgama ukusuka kwi-UAV ukuya kwiziko lolawulo lomhlaba li-11km, i-SNR i malunga + ne-6 okanye + 7, kwaye izinga lokudluliselwa kwedatha yi-7-8Mbps.

21Ingaba iyaxhuma rhoqo?

FHHS ukutsiba-tsiba rhoqo kumiselwa yi-algorithm eyakhelweyo. I-algorithm iya kukhetha eyona ndawo ilungileyo yokuphindaphinda ngokusekwe kwimeko yophazamiseko lwangoku kwaye emva koko iphumeze i-FHSS ukutsibela kweyona ndawo ilungileyo.
