Kugwira ntchito kumadalira zinthu ziwiri izi: (1) Chipangizochi sichingabweretse kusokoneza koopsa, ndipo (2) chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera. Zipangizozi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B, motsatira Gawo 15 la Malamulo a FCC. Malire awa adapangidwa kuti apereke chitetezo chokwanira ku kusokoneza koyipa pakukhazikitsa nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito, komanso chimatha kuwunikira mphamvu zamawayilesi ndipo, ngati sichinayikedwe ndi kugwiritsidwa ntchito motsatira malangizo, chikhoza kusokoneza mawayilesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chipangizochi chikuyambitsa kusokoneza koopsa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchito akulimbikitsidwa kuyesa kukonza kusokonezako ndi chimodzi mwazinthu izi:
- Yankhanitsaninso kapena sinthani mlongoti wolandira.
- Wonjezerani kulekana pakati pa zida ndi wolandila.
- Lumikizani chipangizocho munjira yosiyana ndi yomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.
- Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe ndi gulu lomwe lili ndi udindo wotsatira malamulowo kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito chipangizochi.
- Chotumizira ichi sichiyenera kukhala pamalo amodzi kapena kugwira ntchito limodzi ndi mlongoti wina uliwonse kapena chopatsira.
Ndemanga ya Industry Canada
Chipangizochi chimagwirizana ndi mulingo wa RSS wopanda laisensi wa Industry Canada. Kugwira ntchito kumadalira zinthu ziwiri izi:
(1) chipangizo ichi sichikhoza kuyambitsa kusokoneza, ndi
(2) chipangizochi chiyenera kuvomereza kusokoneza kulikonse, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera ya chipangizocho.
- KODI ICES-3 (B) / NMB-3 (B)
- Chipangizocho chitha kungosiya kufalitsa ngati palibe chidziwitso chotumizira kapena kulephera kugwira ntchito. Zindikirani kuti izi sizikutanthauza kuletsa kufalitsa mauthenga olamulira kapena zizindikiro kapena kugwiritsa ntchito ma code obwerezabwereza pamene akufunikira luso lamakono.
- chipangizo chogwirira ntchito mu bandi 5150-5250 MHz ndichogwiritsidwa ntchito m'nyumba kuti muchepetse kusokoneza koopsa kwa makina a satana am'manja;
- kupindula kwakukulu kwa mlongoti komwe kumaloledwa pazida zamagulu 5250-5350 MHz ndi 5470-5725 MHz kudzatsatira malire a eirp, ndi
- kupindula kwakukulu kwa mlongoti wololedwa pazida zomwe zili mu bandi 5725-5825 MHz ziyenera kutsata malire a eirp otchulidwa pogwiritsira ntchito nsonga ndi nsonga momwe kuli koyenera.
Kuphatikiza apo, ma radar amphamvu kwambiri amaperekedwa ngati ogwiritsa ntchito oyambira (ie ogwiritsa ntchito patsogolo) amagulu a 5250-5350 MHz ndi 5650-5850 MHz, ndipo ma radar awa amatha kusokoneza komanso / kapena kuwonongeka kwa zida za LE-LAN.
Chidziwitso Chokhudzana ndi Ma radiation
Chida ichi chimagwirizana ndi malire a FCC/IC owonetsera ma radiation omwe akhazikitsidwa kumalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20 cm pakati pa radiator ndi thupi lanu.
Chipangizochi chimapangidwira ophatikiza a OEM okha pamikhalidwe iyi:
(1) Mlongoti uyenera kukhazikitsidwa kotero kuti 20 cm imasungidwa pakati pa antenna ndi ogwiritsa ntchito,
(2) Gawo la transmitter silingakhale limodzi ndi cholumikizira china chilichonse kapena mlongoti.
(3) Chowulutsira pawailesi ichi chikhoza kugwira ntchito pogwiritsa ntchito mlongoti wamtundu wamtundu komanso phindu lalikulu (kapena lochepera) lovomerezedwa ndi Texas Instrument. Mitundu ya tinyanga tating'ono yomwe sinaphatikizidwe pamndandanda, wokhala ndi phindu lalikulu kuposa kuchuluka komwe kwawonetsedwa pamtunduwu, ndizoletsedwa kugwiritsidwa ntchito ndi chotumizira ichi.
