Inā ua haka pono ʻoe i kāu kelepona, e noʻonoʻo ana no ke aha he 1 bar kāu i hoʻokahi minuke a me 3 i ka minuke aʻe—a i ʻole no ke aha e hāʻule ai kāu mau kelepona ʻoiai ke ʻōlelo ʻia he lawelawe kāu—ua ʻike paha ʻoe i ka huaʻōlelo"dBm" i kekahi manawa. Ua hoʻolilo au i 14 mau makahiki e hoʻoponopono ana i nā pilikia hōʻailona kelepona no nā home, nā keʻena, a me nā wahi kuaʻāina mamao loa, aHiki iaʻu ke haʻi aku iā ʻoe: ʻo dBm ke code huna no ka hoʻomaopopo ʻana i ka ikaika (a i ʻole ka nāwaliwali) o kāu hōʻailona kelepona. A ʻo ka ʻāpana maikaʻi loa?IʻAʻole ia i paʻakikī e like me ke kani ʻana—e ʻae mai iaʻu e wehewehe iā ia me he mea lā e kamaʻilio ana mākou ma luna o ke kīʻaha kope.
ʻO ka mea mua, e hoʻomaopopo kākou i hoʻokahi mea: ʻo dBm ke kū nei no "decibels e pili ana i hoʻokahi milliwatt." ʻIke wau, kani like ia me ka ʻōlelo loea, akā ʻo nā mea āpau āu e pono ai e hoʻomanaʻo ʻo kēia:ʻO dBm ke anakahi e ana i ka ikaika o ka pilina o kāu kelepona i kahi hale kiaʻi keleponaʻAʻole e like me ka hapa nui o nā helu āu i maʻa mau ai—kahi ʻoi aku ka maikaʻi o ka nui—hana hope ʻo dBm. ʻO ka kokoke ʻana o ka helu i ka 0, ʻoi aku ka ikaika o kāu hōʻailona. ʻO ka ʻoi aku ka maikaʻi ʻole, ʻoi aku ka nāwaliwali. ʻO ia ka hewa mua a ka hapa nui o ka poʻe e hana ai: ʻike lākou i kahi helu e like me -80 a manaʻo he ʻoi aku ka ʻino ma mua o -60, akā ʻo ka ʻaoʻao ʻē aʻe ia.
E hana kākou i kēia me nā helu honua maoli—nā mea āu e ʻike maoli ai ma kāu kelepona. Inā ʻo kāu dBm ma kahi o -50 a i -70, aia ʻoe ma kahi kūpono. ʻO ia nā pā piha, nā kelepona maopopo loa, a me ka ʻikepili wikiwiki—ʻaʻohe buffering, ʻaʻohe kelepona i hāʻule, ʻo ka pilina maʻalahi wale nō. ʻO kēia ka mea āu e loaʻa ai inā ʻoe e kū pono ana ma kahi hale kiaʻi kelepona, a i ʻole ma kahi ākea me nā mea keakea ʻole.
I kēia manawa, inā ma waena o -70 a me -90 kāu dBm, maikaʻi nō ia—e loaʻa iā ʻoe he 2-3 mau pā, a e hana maikaʻi ka hapa nui o nā kelepona a me nā polokalamu. E ʻike paha ʻoe i kahi lohi iki o ka ʻikepili i kēlā me kēia manawa, ʻoiai ma nā wahi hana nui, akā ʻaʻohe mea e hopohopo ai. ʻO kēia ka ikaika hōʻailona maʻamau i ka hapa nui o nā hale a me nā keʻena ʻaʻole mamao loa mai kahi hale kiaʻi.
Hoʻomaka ka pilikia ke paʻi ʻoe i ka -90 a i ka -110 dBm. ʻO ia hoʻi 1 bar (a i ʻole "ʻaʻohe lawelawe" i kekahi manawa), a e hoʻomaka ʻoe e loaʻa nā pilikia: hāʻule nā kelepona i waenakonu o ke kamaʻilio ʻana, lōʻihi ka hoʻouna ʻana i nā leka uila, a ʻaʻole hiki ke kahe ʻana. He mea maʻamau kēia ma nā hale papahele, nā hale pā mānoanoa, a i ʻole nā wahi mamao loa mai nā hale kiaʻi kelepona—e like me nā hale kuaʻāina a i ʻole i loko o nā keʻena nui.
A inā he -110 a haʻahaʻa paha kāu dBm? He wahi make kēlā. Paʻakikī paha kāu kelepona e hoʻopili, a inā paha, ua nāwaliwali loa ka hōʻailona a he mea ʻole ia. ʻIke mau wau i kēia ma nā hale kaʻa kaʻa ma lalo o ka honua, nā tunnels, a i ʻole nā hale i hoʻopuni ʻia e nā lāʻau kiʻekiʻe a i ʻole nā mauna—nā wahi i hiki ʻole ai i ka hōʻailona ke komo maʻalahi.
Ke noʻonoʻo nei paha ʻoe: pehea e nānā ai i kaʻu dBm? He maʻalahi ia, a ʻaʻole pono ʻoe i nā mea hana nani. Ma kahi iPhone, hiki iā ʻoe ke hoʻohana i ke ʻano hoʻāʻo kahua (e kelepona wale i ka *3001#12345#* a kaomi iā “LTE” a laila “Serving Cell Meas”) e ʻike i kāu dBm pololei. Ma ka Android, loaʻa i ka hapa nui o nā kelepona kahi koho "Signal Strength" ma ka polokalamu Settings, a i ʻole hiki iā ʻoe kehoʻoiho i kahi polokalamu manuahi e like me CellularZ e loaʻa ai kahi heluhelu maopopo.Ke ʻike ʻoe i kāu dBm, e ʻike pono ʻoe i ka ikaika o kāu hōʻailona - a inā pono ʻoe e hana i kekahi mea e pili ana i ia mea.
Eia ka mea aʻu e haʻi aku nei i kaʻu mau mea kūʻai aku a pau: ʻaʻole pono ʻoe e noho me ka hōʻailona nāwaliwali. Inā mau kāu dBm ma lalo o -90, amea hoʻonui hōʻailona pūnaewele kelepona paʻalima hiki ke kōkua. Huki ia i kēlā hōʻailona dBm nāwaliwali a maikaʻi ʻole mai waho, hoʻonui iā ia, a hoʻouna iā ia i loko o kou wahi—e hoʻohuli ana i ka -100 dBm i -70 a ʻoi aku paha, no laila loaʻa hou iā ʻoe ka lawelawe hilinaʻi, e mālama i kāu kālā no kahi mea e hoʻoponopono maoli ai i kahi pilikia.
Ua ʻike au i ka nui o ka poʻe e kūʻai ana i nā mea hoʻoikaika ʻaʻole pono lākou, no ka mea wale nō lākou e manaʻo nei "ʻoi aku ka maikaʻi o ka hōʻailona." Akā, aʻo mai ʻo dBm iā mākou e pili ana i ke kaulike—pono ʻoe i ka hōʻailona lawa e hoʻopau ai i ka hana. ʻO ke kī, ʻo ia ka ʻike ʻana i kāu mau helu, i hiki iā ʻoe ke hoʻoholo i kahi hoʻoholo naʻauao.
Inā ʻoe e huikau nei e pili ana i kāu heluhelu dBm, a i ʻole ʻaʻole ʻoe maopopo inā kūpono kahi mea hoʻonui hōʻailona iā ʻoe, mai kānalua e hoʻokaʻaʻike mai. Hauʻoli wau e alakaʻi iā ʻoe ma ka nānā ʻana i kāu hōʻailona, e wehewehe ana i ke ʻano o kāu mau helu, a e kōkua iā ʻoe e ʻike i kahihoʻonā maʻalahi e pili ana i ka uhi hōʻailonakūpono ia no kou wahi. ʻAʻohe ʻōlelo hoʻopunipuni, ʻaʻohe hoʻolaha kūʻai aku—he ʻōlelo aʻoaʻo pololei wale nō mai kahi mea nāna i hoʻoponopono i nā pilikia hōʻailona no nā makahiki he ʻumi.
