Tomas Chlebek Mai ka liʻiliʻi o nā lā antennagate o ka iPhone 4, ʻo ka pololei o ka hōʻailona hōʻailona hōʻailona ma nā smartphones he kumuhana maʻamau o ke kūkākūkā. ʻO ka poʻe i hilinaʻi ʻole i nā pōʻai ʻole a piha i ke kihi o ka hōʻike hiki ke hoʻololi maʻalahi iā lākou me kahi helu e pono ai, ma ka liʻiliʻi loa, e hāʻawi i kahi waiwai hilinaʻi.
Ana ʻia ka ikaika hōʻailona ma decibel-milliwatts (dBm). ʻO ia ke ʻano o kēia ʻāpana e hōʻike i ka ratio ma waena o ka waiwai i ana ʻia a me hoʻokahi milliwatt (1 mW), e hōʻike ana i ka mana o ka hōʻailona i loaʻa. Inā ʻoi aku ka kiʻekiʻe o kēia mana ma mua o 1 mW, ʻoi aku ka maikaʻi o ka waiwai i ka dBm, inā haʻahaʻa ka mana, a laila ʻino ka waiwai i ka dBm.
Ma keʻano o kahi hōʻailona pūnaewele pūnaewele me nā smartphones, he haʻahaʻa mau ka mana, no laila aia kahi hōʻailona maikaʻiʻole ma mua o ka helu ma ka pūʻulu dBm.
Ma kahi iPhone, ʻo ke ala maʻalahi loa e nānā i kēia waiwai penei:
- E hoʻokomo i ka *3001#12345#* ma ke kahua kelepona (Phone -> Dialer) a kaomi i ke pihi ʻōmaʻomaʻo e hoʻomaka i ke kelepona. E hoʻokomo kēia ʻanuʻu i ka hāmeʻa i ke ʻano Field Test (hoʻohana ʻia e ka paʻamau i ka wā lawelawe).
- Ke ʻike ʻia ka pale Field Test, e kaomi a paʻa i ke pihi hiamoe a hiki i ka ʻike ʻana o ka pale pani. Mai hoʻopau i ke kelepona (inā ʻoe e hana, ʻaʻohe hewa e hiki mai, akā pono ʻoe e hana hou i ke kaʻina hana).
- E kaomi a paʻa i ke pihi papapihi a hiki i ka ʻike ʻia ʻana o ka pākaukau. A laila, ma ka ʻaoʻao hema hema o ka hōʻike, ma kahi o nā pōʻai maʻamau, ʻike ʻia ka waiwai helu o ka ikaika hōʻailona ma dBm. Ma ke kaomi ʻana i kēia wahi, hiki ke hoʻololi i waena o ka hōʻike maʻamau a me ka hōʻike ʻana i ka waiwai helu.
Inā makemake ʻoe e hoʻololi hou i ka hōʻike maʻamau o ka ikaika hōʻailona, e hana hou i ka ʻanuʻu 1 a ma hope o ka hōʻike ʻia ʻana o ka pale Field Test, e kaomi pōkole wale i ke pihi papapihi.
ʻO nā waiwai i loko o ka dBm, e like me ka mea i wehewehe ʻia ma luna nei, maʻa mau ʻole no nā polokalamu kelepona, a ʻoi aku ka kokoke o ka helu i ka zero (ʻo ia hoʻi, ʻoi aku ka kiʻekiʻe o ka waiwai, e noʻonoʻo ana i ka hōʻailona maikaʻi ʻole), ʻoi aku ka ikaika o ka hōʻailona. ʻOiai ʻaʻole hiki ke hilinaʻi piha ʻia nā helu i hōʻike ʻia e ke kelepona, hāʻawi lākou i kahi hōʻailona pololei loa ma mua o kahi kiʻi kiʻi maʻalahi o ka hōʻailona. ʻO kēia no ka mea ʻaʻohe mea e hōʻoiaʻiʻo i ke ʻano o ka hana ʻana a, no ka laʻana, ʻoiai me ʻekolu mau apo piha, hiki i nā kelepona ke hāʻule i waho, a ma ka mea ʻē aʻe, hiki i kekahi ke manaʻo i kahi hōʻailona ikaika loa i ka hana.
I ka hihia o nā waiwai dBm, ʻoi aku ka nui o nā helu ma mua o -50 (-49 a ma luna) a pono e hōʻike i kahi kokoke loa i ka transmitter. He kiʻekiʻe loa nā helu mai -50 a hiki i -70 a kūpono no ka hōʻailona kiʻekiʻe loa. ʻO ka awelika a me ka ikaika hōʻailona maʻamau e like me -80 a -85 dBm. Inā pili ka waiwai -90 a -95, ʻo ia ka hōʻailona haʻahaʻa haʻahaʻa, a hiki i -98 unreliable, a hiki i -100 hiki ʻole ke hilinaʻi.
ʻO ka ikaika hōʻailona ma lalo o -100 dBm (-101 a ma lalo) ʻo ia ka mea hiki ʻole ke hoʻohana. He mea maʻamau ka hoʻololi ʻana o ka ikaika hōʻailona ma ka liʻiliʻi o ʻelima dBm, a ʻo nā mea e like me ka helu o nā mea i pili i ka hale kiaʻi, ka helu o nā kelepona e holomua ana, ka hoʻohana ʻana i ka ʻikepili kelepona, a me nā mea ʻē aʻe. hopena ma keia.
ʻoiai ua hoʻopili ʻia kēia e nā mea e like me ka helu o nā mea i pili i ka hale kiaʻi, ka helu o nā kelepona i ka holomua, ka hoʻohana ʻana i ka ʻikepili kelepona, etc.
… hopu ʻia nā mea hana… :-D
a i ʻole, ke hele ke kanaka ma ka ʻaoʻao home, ma ke kaomi ʻana i kahi manamana lima ma ka hōʻailona, hoʻololi ia ma waena o nā kiko a me ka dBm...
Pololei, koi ʻia kekahi i nā code ikaika a me nā kaʻina hana me nā pihi, ʻo ka mea wale nō āu e hana ai, ʻo ka paʻi ʻana i kou manamana lima ma ka hōʻailona a hoʻololi i hope a i waho. ? ʻAe, ma ka liʻiliʻi hoʻokahi mea kupanaha i ka papa kuhikuhi huna, kahi mea e pono ai. ?
Ua ho'āʻo wau, akā ʻaʻole i hana me ka ʻole o ka code device i7 a me ka polokalamu hou loa
Loaʻa iaʻu kahi iP5, ka iOS hou loa, a hana ia ma ka pale laka, ke komo ʻana i kahi code, a ma nā papapihi me nā kiʻi. ʻAʻole maopopo iaʻu ke ʻano o nā mana hou o ke kelepona, e nīnau wau i kahi hoa hana. ?
A inā makemake au e hoʻihoʻi i kona kūlana mua? Mahalo
Kākau mākou ma ka kikokikona: Inā makemake ʻoe e hoʻololi hou i ka hōʻike maʻamau o ka ikaika hōʻailona, e hana hou i ka ʻanuʻu 1 a ma hope o ka hōʻike ʻia ʻana o ka pale Field Test, e kaomi pōkole wale i ke pihi papapihi.
Nui, mahalo nui!
Hōʻike iaʻu -110 a ma kahi o -89, no laila ʻaʻole maopopo iaʻu kahi o ka hewa. Hana ke kelepona.
Loaʻa iaʻu ma laila - 102 a i ka wā e hoʻololi ai i 3 mau pahu. Akā, ua lawa ka hōʻailona, hana maikaʻi nā mea a pau. A e like me kāu, ʻaʻole pono. ʻAe, ʻaʻole maopopo iaʻu……………………
