lohi i nā kumu pūnaewele
Aia ka wikiwiki o ka pūnaewele i nā kumu he nui, ʻo ka mea nui o ia mau mea: ʻO ke kūlana laina ʻāina Hoʻopili ia i ka wikiwiki o ka Pūnaewele i loaʻa i ka mea hoʻohana mai ka lawelawe pūnaewele.
Inā ʻoe e kau inoa i ka wikiwiki o 30 Mbps, pono ke maikaʻi o ka laina i mea e loaʻa ai kēia wikiwiki
Ma waena o nā kumu i kaohi i ka maikaʻi o ka laina:
Hōʻailona hōʻailona hōʻailona i SNR
ʻO ka lakio hōʻailona-a-kani kahi waiwai i ana ʻia i nā decibels (dB) a wehewehe i ka pilina ma waena o ka pae o ka ikaika o ka hōʻailona o ka ʻikepili e hele ana i ka laina kelepona me ke kani e pili ana i ka laina. ʻOiai nā uwea maikaʻi e hoʻopili i kekahi kani.
Kupaianaha kēia 'ka walaʻau'ʻo ia ka hoʻopili electromagnetic i hoʻokumu ʻia e:
ʻO nā kaula ʻē aʻe kokoke i ka laina kelepona e like me uwea kiʻekiʻe A me ke kaula coaxial e hoʻoili i ka hōʻailona TV.
- alakaʻi ʻilihune.
Nā motika a me nā mea hoʻololi uila kokoke i ke kaula uila.
ʻO nā hale kiaʻi lekiō, ʻo ia hoʻi kēlā mau hale kiaʻi e lawe i nā hōʻailona electromagnetic i ka pae lekiō lekiō, e like me nā hale kiaʻi kamaʻilio, ka Pūnaewele, a me nā hoʻolaha leo.
ʻO ke kiʻekiʻe o ka decibel waiwai, ʻoi aku ka nui o ka waiwai o. SNR ʻO ka maikaʻi o kāu laina, ʻoi aku ka ikaika o ka hōʻailona ma mua o ke kani.
- Inā he 29 dB a ʻoi paha ke kumukūʻai, ʻo ia hoʻi, nāwaliwali loa ke kani a hōʻike kēia i ka maikaʻi o ka laina.
- Inā aia ka waiwai ma waena o 20-28 dB, maikaʻi loa kēia, ʻo ia hoʻi he maikaʻi ke aho aʻaʻohe pilikia e pili ana i ka wikiwiki.
- Inā loaʻa ka waiwai ma waena o 11-20 dB ʻae ʻia kēia.
- Inā ʻoi aku ka waiwai ma lalo o 11 dB, maikaʻi ʻole kēia a nui ke kani o ka hōʻailona, e hoʻopili ai i ka wikiwiki o ka Pūnaewele.
Hoʻoiho Attenuation
Kuhi ʻia kēlā me kēia uwea ma ka Honua i ka attenuation.
ʻO ke ana e wehewehe ana i ka nalo o ka ikaika o ka hōʻailona ke hele ma waena o ke kaula uila. Aia kēia waiwai i ka mamao ma waena o ka mea hoʻohana a me ke kālepa kelepona, a me ke ʻano o ka laina keleawe ponoʻī. Hoʻoiho Attenuation ʻO kēia ke kumu o ka nui o ka nalo ʻana i ka ikaika o ka hōʻailona e hele ana i ka laina, i kumu e komo maikaʻi ʻole ai i ka Pūnaewele a no laila ʻo ka wikiwiki haʻahaʻa ma mua o ka ʻaelike me ka lawelawe lawelawe Pūnaewele.
A ʻo ka hope, ʻo ka liʻiliʻi o ka mamao ma waena o ʻoe a me ke kālepa kelepona, ʻo ka haʻahaʻa o ka waiwai o Hoʻoiho Attenuation Kuhi kēia e loaʻa iā ʻoe kahi pūnaewele pūnaewele wikiwiki aʻe.
Inā he 20 dB a ʻoi paha ka liʻiliʻi, maikaʻi loa ia.
Inā aia ka waiwai ma waena o 20-30 dB, maikaʻi loa kēlā.
- Inā ʻo ka waiwai ma waena o 30-40 dB maikaʻi loa ia.
Inā ka waiwai ma waena o 40-50 dB maikaʻi ia.
Inā ʻoi aku ka waiwai ma mua o 50 dB maikaʻi ʻole kēia a e loaʻa ʻoe i ka pūnaewele intermittent a me ka wikiwiki maikaʻi ʻole.
Hoʻopili pololei ʻia ka wikiwiki pūnaewele e Hoʻoiho Attenuation Minamina, inā mamao loa ka mamao ma waena o ʻoe a me ke kelepona, ʻaʻohe mea hiki iā ʻoe ke hana e pili ana i ka pilikia lohi koe wale nō e hoʻopili aku i kāu poʻe hana pae ʻāina a haʻi iā lākou makemake ʻoe e hele i kahi kūʻai kelepona kokoke loa.
He aha kaʻenehana ADSL a pehea e hana ai?
Aia kekahi mau ʻōlelo aʻoaʻo e hiki iā ʻoe ke hana e hoʻomaikaʻi i ka lakio hōʻailona-i-kani (SNR)
• Kūʻai i kahi router maikaʻi loa Hiki ke mālama i ka lakio o SNR haʻahaʻa.
• Hoʻohana Splitter ʻO ke kūlana maikaʻi e hoʻokaʻawale i ke kahawai kelepona mai ka pūnaewele pūnaewele i ka laina keleawe.
No ke aha mākou e hoʻohana ai i ka mahele?
• Hoʻololi i nā kaula hoʻohui a hoʻohana i nā kaula hou a maikaʻi loa, no ka mea hiki i nā kaula maikaʻi maikaʻi ʻole ke hoʻopili i ka laina.
E wehewehe pehea e kāpae ai i ka lawelawe pūnaewele home lohi
A aia ʻoe i ke olakino a me ka palekana o kā mākou poʻe aloha
