Kodi IWAVE's FHSS Technology ndi chiyani?
Kudumpha pafupipafupi kumatchedwansofrequency hopping spread spectrum (FHSS)ndi njira yamakono yotumizira ma siginecha apawailesi pomwe zonyamulira zimasinthira mwachangu pakati pa mawayilesi osiyanasiyana osiyanasiyana.
FHSS imagwiritsidwa ntchito popewa kusokonezedwa, kupewa kumvetsera, komanso kuti athe kulumikizana ndi ma code-division multiple access (CDMA).
Pankhani ya frequency hopping function,IWAVEgulu ali aligorivimu awo ndi limagwirira.
Chogulitsa cha IWAVE IP MESH chidzawerengera mkati ndikuwunika ulalo wapano kutengera zinthu monga kulandilidwa kwamphamvu kwa siginecha RSRP, chiŵerengero cha signal-to-noise SNR, ndi bit error rate SER. Chiweruzo chake chikakwaniritsidwa, idzachita kudumphadumpha pafupipafupi ndikusankha ma frequency oyenera pamndandanda.
Kudumphadumpha pafupipafupi kumatengera ma waya opanda zingwe. Ngati mawonekedwe opanda zingwe ali abwino, kulumpha pafupipafupi sikungachitike mpaka chiweruzo chikwaniritsidwe.
Blog iyi iwonetsa momwe FHSS idatengera ndi ma transceivers athu, kuti timvetsetse bwino, tidzagwiritsa ntchito tchati kuwonetsa izi.
Kodi Ubwino wa IWAVE wa FHSS ndi Chiyani?
Ma frequency band amagawidwa m'magulu ang'onoang'ono. Zizindikiro zimasintha mwachangu ("hop") ma frequency awo onyamula pakati pa ma frequency apakati amagulu ang'onoang'onowa motsimikiza. Kusokoneza pafupipafupi pafupipafupi kudzakhudza chizindikiro pokhapokha pakapita nthawi yochepa.
FHSS imapereka maubwino 4 pamayendedwe okhazikika:
Zizindikiro za 1.FHSS zimagonjetsedwa kwambiri ndi kusokoneza kwa narrowband chifukwa chizindikirocho chimadumphira kumagulu osiyanasiyana.
2.Signals ndizovuta kutengera ngati mawonekedwe odumphira pafupipafupi sakudziwika.
3.Jamming imakhalanso yovuta ngati chitsanzo sichidziwika; chizindikirocho chikhoza kutsekedwa kwa nthawi imodzi yokha yodumphira ngati kufalikira sikudziwika.
Kutumiza kwa 4.FHSS kumatha kugawana ma frequency band ndi mitundu yambiri yapanthawi yopatsirana ndi kusokoneza kochepa. Zizindikiro za FHSS zimawonjezera kusokoneza kochepa pamalumikizidwe ocheperako, komanso mosemphanitsa.
