Pūʻulu kelepona

GPS hana:
Hoʻolako ʻia me kahi antenna GPS e hana ana ma 1575.42 MHz ± 5 MHz, e hōʻike ana i ka polarization circular lima ʻākau (RHCP) a me ka loaʻa kiʻekiʻe o 28 ± 3 dBi no ka hoʻokele kaʻa pololei a hilinaʻi.

ʻElua WiFi hiki:
ʻElua mau antenna WiFi e kākoʻo ana i ka band frequency 2.4 GHz (2400-2500 MHz) me ka polarization vertical a me ka loaʻa ʻana o 2 dBi, kūpono no ka hoʻonui ʻana i ka hōʻailona hōʻailona uila i nā kaʻa kaʻa a i ʻole nā ​​​​kaiapuni.

ʻOi aku ka maikaʻi o ke kūkulu ʻana:
Hana ʻia me ka hale plastik i hōʻoia ʻia e ROHS a me ke kaula coaxial RF1.13 kiʻekiʻe e hōʻoiaʻiʻo ana i ka lōʻihi mau loa a me ka hoʻouna ʻana i nā hōʻailona paʻa i nā kūlana paʻakikī.

Ke noi ākea:
Kūpono no ka hoʻokele GPS kaʻa, ka hoʻokele ʻauwaʻa, ka hoʻonui ʻana i ke kamaʻilio kelepona, a me nā ʻōnaehana telematics ʻokoʻa e koi ana i ka hoʻokipa ʻana i nā hōʻailona he nui.

Kaiapuni hana:
Hoʻohana hilinaʻi ʻia ma kahi ākea ākea mai -40°C a +85°C a kākoʻo i nā kaiapuni haʻahaʻa kiʻekiʻe, e hōʻoiaʻiʻo ana i ka hana paʻa i nā ʻano piʻi.
