FHSS, inshuro nyinshi ikwirakwiza ikwirakwizwa rya tekinoroji, muburyo bwo guhuza no icyarimwe, yemera ibimenyetso byoherejwe nabatwara imirongo migari yubwoko runaka (iyi fomu yihariye ifite inshuro yihariye, nibindi) kumpera zombi.Kubakira nta bwoko bwihariye, ibimenyetso byizerwa byakozwe na FHSS ni urusaku gusa kuri byo kandi ntabwo bizakira iki gice cyibimenyetso.
Kuki FHSS ikenewe?Nibyo, amakuru yoherejwe ntabwo azaba manini gusa murwego rwagenwe.Niba igihe cyo kohereza cyapaki imwe yamakuru gishobora kurenza igihe ntarengwa cyo guturamo cyemewe namabwiriza abigenga, tekinoroji ya FHSS izakoreshwa.Kugirango ushoboze uburyo bwo gutegera inshuro nyinshi muri Lora, koresha igihe cya reg hopping nigihe cyo kwandikisha ibihe kugirango ubishyire kumurongo utari zeru.Ibikurikira bisobanura ingingo zubumenyi bwiki gice binyuze mumahame.
Ihame:Ihame ryakazi rya FHSS yumurongo wo gukwirakwiza gukwirakwiza gahunda ni: ko mugihe ibyiringiro bisabwa kubice bya buri paki yamakuru ya Lora, ibikubiyemo bigomba koherezwa binyuze mumurongo wihuta washyizweho nubuyobozi bwa MCU.Inshuro zigomba gusabwa koherezwa ukurikije imbonerahamwe yibibazo.Nyuma yo kohereza amakuru arangiye kandi igihe cyagenwe cyagenwe cyateganijwe kirangiye, utanga ubutumwa hamwe nuwakiriye bahindukirira umuyoboro ukurikira murutonde rwateganijwe mbere yo gukomeza kohereza no kwakira igice gikurikira cyapaki yamakuru.Igihe cyo gutura mumurongo uwo ariwo wose kigenwa nigihe cyo gutegera inshuro, ni integer nyinshi yuburebure bwikimenyetso.
Inzira yo koherezano kwakira binyuze muri frequency hoping itangirira kumuyoboro 0. Ijambo ryibanze n'umutwe byanyuzwa kumuyoboro 0 ubanza.Igihe cyose ipaki yamakuru yoherejwe, isomwa ryumuyoboro wa konte kumuyoboro wubu (uherereye kumuyoboro wa reg hopping) uziyongera, kandi hazashyirwaho ikimenyetso cyo guhagarika umuyoboro wa FHSS kugirango uhinduke.Imirongo mishya igomba gushyirwaho mugihe cyo gutezimbere kugirango tumenye neza ko imirongo mishya izashyirwa mugihe gikurikiraho.Kugenzura inzira: tangira kwakira FHSS kumuyoboro 0. Nyuma yo kugenzura ibanzirizasuzuma, uwakiriye azatangira inzira yo gutezimbere inshuro nyinshi.Muri iki gihe, niba CRC yumutwe itariyo, uyakira azahita asaba umuyoboro 0 (packet retransmission mechanism) hanyuma utangire kugenzura preamble.
Ingingo yavuzwe haruguru ibisobanuro byihame rya frequency hopping ikwirakwiza itumanaho (FHSS) yazanwe naweShenzhen HDV Phoelectron Technology Co., Ltd..Twizere ko iyi ngingo ishobora kugufasha kongera ubumenyi.Usibye iyi ngingo niba ushaka ibikoresho byiza bya fibre itumanaho ibikoresho bya sosiyete ushobora gutekerezaibyerekeye twe.
